The 10 best phones of 2015

10. Huawei Ascend P7

The progress of the Huawei brand has been spectacular in the past two years, which has gone from making feature phones and quality, in some cases, questionable, to create devices that rub shoulders with the most desired market and all this at a considerably lower price. Just over six months ago that the Chinese company launched the Huawei Ascend P7, a phone with 5-inch screen and a resolution of 1,920 x 1,080 pixels with two cameras, one front and 8 megapixel rear of 13, which also stands out its acceptable range. It runs on Android and allows the use of 4G networks. Expert Rating: 3 stars have an affordable price and a more typical mobile upper-middle range of qualities. Perhaps it lacks a bit processor and is somewhat slow transitions, which could have been supplemented with a better processor, but the phone is one of the best you can find a good price in the catalog of many operators. Free price: 289 euros

9. Google Nexus 6

After the success of the Nexus 5, Google was expected to "break the market" with the new model in the series. However, what he did was try to reinvent it with a device that is a cross between a phone and tablet mobile itself. The Nexus 6 has a screen of 5.95 inches, its resolution is qHD (2560 x 2160 pixels) and one of its strengths is its Snapdragon 805 processor, with 3GB of RAM and at least 32GB storage (but not including reader microSD) card Your camera has 13 megapixels (which does not improve previous models) and the main "but" you can put the device is its battery as it only provides about 8 hours of autonomy. Expert Rating: 3 stars While the Google Nexus 5 was unrivaled in terms of money, with this 'phablet' Mountain View firm has spent slightly to set the value of sale. Interesting because of its size and because of the Google factory, but nothing more. Free price: 599 euros

8. One Plus One

If you have not heard of this phone is its exclusive character and because there is no great traditional manufacturer behind him. However, when you meet him, he will become an outstanding among your options to buying a new terminal candidate. He put on sale last June by invitation system. The tricky thing is to get one of these "VIP pass" to be with the phone, but if achieved, the 16GB version can be purchased for 269 euros. The 64 GB costs only 30 euros more, which compensates. It has a 5.5-inch screen at 1080 pixels, which has some problems in terms of brightness, although One already been resolved. Its rear camera is 13 megapixels and the front is 5 megapixels. It supports LTE (4G services that provide high-speed Internet) Expert Rating: 3.5 stars Possibly the revelation of last season. We are glad that the One Plus One into our ranking of best phones because it shows that the market for mobile telephony is no longer in the hands of a few manufacturers. Anyone with a good product can surprise and be a bestseller. Free Price: from 269 euros

7. Xiaomi Mi 4

Mindful of this name if you do not know: Xiaomi. It is a Chinese manufacturer with all kinds of phones, much lower as powerful devices that tutean except in price, which is Menor- the iPhone 5. We ranges this example because Xiaomi Mi4 design, the phone sneaks into the top 8 of our 'ranking' is very similar to the Apple device. But of course, the material that is made can not be the same: the back cover is plastic. It has a 5 inch screen with a resolution of 1920 x 1080 pixels. It has a 13 megapixel camera on its back and another 8 in the front. The battery is quite powerful 3080 mAh and can be connected almost 24 hours. That itself is not removable. As operating system uses a variant of Android, MIUI 6 significantly faster but can cause some compatibility problems with some applications not common. Expert Rating: 3.5 stars If you are an 'early adopter' (people who love to be the first to enjoy the technological innovations) will not surprise the brand Xiaomi. If you do not know, it's worth it into account when buying a new phone that is giving a lot to talk about. Free price: 329 euros

6. LG G3

Although the latest handset from LG is the LG Flex 2, presented at the last CES held in January in Las Vegas (United States), we were on this ranking with the LG G3, although already a few months, surprised the improve the characteristics of G2. Noted for its 5.5-inch screen with QHD resolution (2560 x 1440 pixels), 2GB of RAM, 16 GB of internal storage ... and the battery is the same as the Xiaomi we saw before but also is removable. The rear camera is 13 megapixels and includes a front 2.1. Rating Expert: 4 stars Within the high-end phones have a lower price, but still, some features remain somewhat 'lame' compared to those who have shown other companies 'top' Asia in recent months. Anyway, not bad taken into account in design and durability. Free price: 599 euros

5. Motorola Moto X

A good price / quality ratio, reason lies in fifth position of our ranking of the best phones Motorola Moto X, something that will surprise many. The phone Motorola, a company that Google acquired two years ago and a half, was released last summer as heir to the Moto G, one of the best quality phones with market price (175 euros). The Moto X is more expensive, but significantly improves performance. It has a 5.2 inch screen, 2 GB of RAM and a Snapdragon processor 801. In what falters is in the battery capacity, which remains at 2,300 mAh. Expert Rating: 4 stars Motorola wanted to imitate the success of the Moto G but the price up a bit. Yet, it is offering good quality and guaranteed to be buying a Google product. Free price: 399 euros

4. Sony Xperia Z3

Last year Sony introduced the third generation of their mobile Z, following the success of the Sony Xperia Z1, a true bestseller in 2012, and Z2. The Z3, meanwhile, is a phone pointer, waterproof, dustproof, who has not left anyone indifferent. It has a 20.7 megapixel camera, with 4K recording / UHD. Its 5.2-inch screen Full HD Triluminos has a high resolution and a pixel density of 441 ppi. It also has a battery with the "stamina mode" allows you to select which applications are updated at all times. As a new member of the family (presumably at MWC 2015) arrives, this phone from Sony holds fourth place in our rankings. Expert Rating: 4 stars Sony managed to outdo itself improving the functionality of Z1 and Z2 with this terminal. Interestingly, although we may have news soon about the renewal of the range. Free price: 629 euros

3. iPhone 5S

The high-end phone Apple lowered its price at the end of last year thanks to the arrival of the iPhone 6, which together with its high performance causes continues to occupy high positions in our ranking despite being a 2013 release features iOS 8 operating system, and its main innovations is fingerprint reader, which allows you to unlock the device only pose the finger, and will also serve to identify you when shopping at the Apple Store. Its front camera, 8 megapixels, offers a more than acceptable quality as well as the back. It incorporates the powerful 64-bit A7 chip,. Expert Rating: 4.5 stars Apple is always Apple. Although no longer the latest models offers very great performance at a more affordable price than the iPhone 6. Free Price: 599 euros Now we put the two best phones of 2015 until llegen their evolution as S6.

2. Samsung Galaxy S5

It took decide the top 3 of our ranking, knowing that fans of the Galaxy S5 prefer Android and Apple certainly will choose the iPhone 6. Anyway everything will change when the appointment of Barcelona arrives and Samsung show their new phones (while Apple may wait for the third quarter of the year to renew its range of devices). Samsung took the rest last year with this phone, successor to the bestselling Galaxy S4 with a 5.1 inch screen and FullHD last Qualcomm Snapdragon 801 to 2.5 GHz. Its rear camera is 16 megapixels. Runs Android 4.4.2 KitKat and its battery is by far the most autonomy presents market: up to 21 hours (compared to 12 hours of iPhone 5S ...). Yes, it weighs a little more than other high-end devices: 145 grams compared to 112 top Apple phone. Expert Rating: 5-star Samsung will soon counteract the thrust of the Apple iPhone 6 and presented at the Mobile World Congress in Barcelona that will be the best phone on the market in 2015, at the expense of a new iPhone is released. Free price: 699 euros

1. iPhone 6

The star of Apple in terms of mobile telephony came last September, growing considerably in size over previous models of the company on the block.

The new iPhone (6 and 6 Plus) include a Retina screen HD 4.7 and 5.5 inches and are equipped with the second generation A8 processor designed by Apple, which has a faster performance and also consumes less battery. Both devices have an 8-megapixel rear camera with a sensor that adds Pixels Focus technology for faster autofocus. In addition, the iPhone 6 Plus technology has optical image stabilization, which helps the pictures come less blur in low-light and works with iOS in August to reduce movement.

The new iPhone work with LTE technology (ie, support for 4G) and can download data rates up to 150 Mb / s and allow even make voice calls over the technology.

Expert Rating: 5 stars

The two new objects of desire to share the limelight among Apple 'fanboys' waiting to be launched in April Apple Watch. Designed to leverage the capabilities of the new operating system iOS 8 have changed their screens -a better- experience to handle an iPhone.

Free Price: From 699 euros


In short if the price is not a problem, if you want to recommend Android S5 and if you like the iPhone iOS 6. Now you know The 10 best mobile 2015.

Sony Alpha a99 SLT-A99V Camera

The Good The Sony Alpha a99 SLT-A99V has a lot going for it, including excellent photos and very good video, a well-constructed and well-designed body, solid performance, and a great feature set.

The Bad For some folks, things like the lack of CompactFlash, poor battery life, and compromises on video autofocus may not be reasonable trade-offs.

The Bottom Line The Sony Alpha SLT-A99V is a generally great camera that's equally adept at both stills and video, but with a few caveats.

I admit, I really didn't like Sony's first full-frame cameras, the DSLR-A900 and its stripped-down sibling, the DSLR-A850. I used to use them as examples of poor noise reduction and for before-and-after examples for the virtues of third-party raw-processing software. But that was almost four years ago, and just before Sony had its "aha!" moment and started churning out excellent sensors, like the one in the Alpha SLT-A99V. The company's flagship (and at least for now, only) full-frame model delivers excellent photos and very good video, and has a well-constructed and intelligently designed body, solid performance, and a great feature set. Despite all the excellence, though, there are some caveats to consider before shelling out the not-inconsiderable amount of dough it costs.
Image quality
The photo quality is great -- pretty much what you'd expect from a full-frame camera -- with well-resolved detail, accurate color (as long as you use the Neutral Creative Style setting), and a broad tonal range with very good latitude in the highlights. Though it doesn't have an antialiasing-filter-free model, the sensor in the A99V incorporates a new selectively applied low-pass filter as a compromise for increased ability to resolve detail.
According to Sony, the sensor also has new noise-reduction algorithms designed to reduce noise only where you need it, but I still find that (oddly) the Nikon D800 outperforms the A99V in this respect, especially around ISO 1600 and above. For JPEGs, photos are extremely clean through ISO 400, and you can start to see some slight edge artifacts appearing at ISO 800. There's a noticeable jump in noise suppression between ISO 1600 and ISO 3200, regardless of how bright the scene is. But I couldn't gain any better noise reduction below ISO 3200 by processing the raw; at ISO 3200 and above I did manage to get some better results, enough to gain about a stop of latitude. Overall, though, while the SLT-A99V is extremely good at ISO 1600 and below, if you need the cleanest-possible high-sensitivity results, the Nikon D800 and Canon EOS 5D Mark III are probably a bit better.
The camera also does an excellent job of preserving highlights in seemingly blown-out areas. I was less impressed with recovering clipped shadow detail, in part because it inevitably introduces a lot of color noise, significantly more so than with the D800.
I was especially impressed with the auto white balance. For one, it handled cloudy shooting conditions properly; a lot of cameras I've tested recently have not. Same goes for balance under our tungsten studio lights. Normally I don't comment on the tungsten results because every camera handles it miserably. On the flip side, though, Sony's default Standard Creative Style pushes hues slightly, throwing off color accuracy. Switching to the Neutral setting delivers the kind of results I expect from a pro camera, though some people might want to tweak the sharpness (like most manufacturers, Sony assumes if you want neutral colors you want no processing at all).
The video quality is very good as well, though here I admit I'm still partial to the warmer tonality delivered by the Canon 5D Mark III and Nikon D800 and the sharper, less noisy low-light video of 5D Mark III.
Performance
Most of the time, the A99V feels responsive and fluid to shoot with. Yes, there's the occasional bout of reluctant autofocus lock and battery death -- for decent battery life you really need the multibattery grip, though that kind of defeats the purpose of making the camera lighter -- and the menus take just a hair longer to come up than I'd like while the camera's processing images. But overall I was happy with the camera's speed.
By the numbers, the A99V offers performance competitive with other full-frame cameras. (Our benchmarks for the 5D Mark III and D800 used different methodology, but our numbers for the Nikon D600 and Canon EOS 6D are comparable.) It powers on and shoots in just under a second -- a little on the slow side. In good light, it takes about 0.4 second to focus, expose, and shoot, which rises to 0.5 second in dimmer conditions; that's relatively good, and partly held back by the somewhat slow-driving but optically excellent lens we used for performance testing, the Zeiss 24-70mm f2.8. Two sequential shots run about 0.3 second for either raw or JPEG, also decent times.
The camera excels at continuous shooting. Sony seems to have rated it pretty conservatively; as long as you stay below the buffer threshold, 20 JPEG shots or 17 raw shots, it can maintain a clip of roughly 6.2 frames per second (at least with a 95MBps SD card). Once you've exceeded the buffer, it slows considerably and erratically, below 3fps. In practice, shooting raw+JPEG, the buffer was less than 10 shots but overall adequate for small bursts.
Despite the tons of technological R&D it sounds like Sony put into the autofocus system, I didn't feel always feel the magic. It has a dual phase-detection AF system, which the company claims improves tracking AF considerably, and a new AF Range control that lets you specify near and far distance limiters for the focus range. I really like the tracking AF interface, with the big green box that follows your subject around the screen, but found that the focus lock just didn't keep up with the promise during continuous shooting, and even with the range limiter enabled I found that tracking box a little too fickle, willing to hightail off after any bigger object that enters the scene. Nonetheless, I had no issues with the AF system that I haven't had with other cameras.
In fact, I think the camera has too many autofocus options, making figuring out which settings you should use a bit too complicated. There are four AF mode choices: single, continuous, auto (which selects between single and continuous), and dynamic (Depth Map Assist Continuous AF), which seems to fine-tune the continuous AF phase-detection focus lock by expanding to the assist the areas. Then there are four AF area options: wide, zone, spot, and local. But the options or combinations that automatically choose the focus areas never seem to choose the correct ones, making it difficult to select the option with any confidence. This isn't a Sony- or A99V-specific issue; it's a problem with most AF systems that still remains despite all the effort.
I'm not sure if I've complained about this elsewhere, but every time you stick a card in, Sony cameras check it for an "Image Database" (a Sony-compatible file-system structure). But if it doesn't find the database, it pops up a message asking if you want to create one. Now, I don't know about you, but every time I stick a card in the first thing I do is format it and Sony's, um, helpfulness gets between me and the format operation, requiring an extra few button presses before I can start working. So no, Sony, I never want to create an image database. Get out of my way! I can sort of understand this on point-and-shoots where people might not realize the need to format, or if they never remove the cards, but on a pro camera it's intrusive and unnecessary.
Both the viewfinder and back display work very well, with no visibility issues in direct sunlight or refresh issues while shooting action, and though I still think that OLED displays are a little too cool and contrasty for cameras -- photos never look better than on those displays, and that's not necessarily a good thing -- Sony lets you adjust the color temperature of the viewfinder.
Design and features
For the most part, the camera body is very well designed and built, with a great grip -- one of the most comfortable I've used -- and an intelligent control layout. It's weather-sealed, though keep in mind that as far as I know Sony only offers two full-frame weather-sealed lenses to match. Yes, the body is also lighter than the competition, but I find once you stick a good lens on it that roughly 6-ounce advantage becomes moot.
All the controls are easily accessible and distinguishable by feel, the mode dial has a central lock button (not my favorite place for it), and everything is as configurable as you'd expect from a camera in its class. I don't think it's the snazziest design -- I'm not crazy about the bulbous look of the buttons boiling up from the surface on the back -- but it's effective and that's more important.

There's only one control I really dislike, and that's the navigation joystick. It simply feels mushy and imprecise.

While I think competitors produce better video quality than the A99V, this is my favorite camera for shooting video. It's one respect in which the fixed-mirror SLT technology gains a huge advantage over SLR. The articulated OLED display, great EVF, and manual-focus peaking make it extremely easy and comfortable to shoot without having to Frankenstein the camera out with a rig, loupe, and other accoutrements. The one, somewhat huge, exception to the love: you can't adjust shutter speed or aperture for video while autofocus is enabled. A lot of videographers use manual focus exclusively, so it won't faze them, but it irks me to no end. And if you don't know this up front, you can spend hours trying to figure out why the camera won't let you adjust those settings.

Sony brings its Silent Controller from its prosumer camcorders for better video control.

While the Silent Controller is intended to allow you to avoid introducing noise while changing settings during video shooting, it's also really nice for simply changing settings without having to drop the camera from your eye. It offers a lot of the same settings as the function menu, but it has a different interface that takes up far less space in the viewfinder.

In addition to the complete set of essential features for a pro camera, the A99V has a couple of unique features for this class, including built-in GPS (which strains the already lackluster battery life a bit), in-camera image stabilization (both Canon and Nikon use lens-based IS), and a built-in stereo microphone (which is nice to have in a pinch). On the downside, some folks may quibble with the decision to incorporate two SD card slots instead of an SD and a CompactFlash; while it would likely make little difference during shooting, CF is still the faster technology for moving files to your computer in a time-sensitive workflow.
If you're a Sony A series shooter disgruntled by the company's lack of tethering support for most of its modern models, the company has updated its Remote Camera Control software to support the A99V. And one note about accessories: the A99V uses the new Multi Interface Shoe, but ships with an adapter if you want to use your old accessories.
For a complete account of the A99V's features and operation, download the PDF manual.
Conclusion
The A99V is a powerful, complicated camera that may simply exceed the needs (or budget) of most photographers, and since Sony doesn't offer a cheaper full-frame model a la the Nikon D600 or Canon EOS 6D, the company's missing out on an opportunity. If you need a single model that can handle both stills and video with equal aplomb, and are willing to make some trade-offs -- sacrificing a little on the video and high-ISO quality as well as video AF -- it's a great choice.

Nikon D750 isn't cheap, but offers a great full-frame value

The Good The Nikon D750 delivers the best photo quality and continuous-shooting performance in its price class, along with a nicely well-rounded feature set.

The Bad Nikon's Wi-Fi implementation is weak and some of the other features could be executed a little better. Plus Live View performance is sad.

The Bottom Line It's not the cheapest camera in its class, but the Nikon D750 delivers an excellent combination of quality, performance and features for its price.

As the long-awaited sucessor to the six-year-old D700, the Nikon D750 delivers admirably. While its $2,300 price tag (£1,800/approximately AU$2,600) inhabits the upper reaches for many enthusiasts, it's a perfect camera for people who are picky about their photographs, who need better high-sensitivity quality than you can get with one of the less-expensive full-frame options or an APS-C-based dSLR, and who need speed for action shooting. Plus, it's a solid option for pros looking for a good value.
The camera comes in a couple of official kit configurations. The $3,000 bundle with the 24-120mm f3.5-5.6 lens is the only Nikon-approved kit in the US, but a 24-85mm f3.5-5.6 kit will also be available in the UK and possibly Australia (I couldn't find any available options with prices at the time this review was published, however).

The D750 will be sold with the 24-120mm lens in the US, plus additional kits with the 24-85mm f3.5-5.6 lens in the UK and possibly Australia. Sarah Tew/CNET

Image quality

Nikon really does a nice job on photo quality. The D750 has an excellent noise profile for both stills and video, and it produces significantly cleaner raw images than the Sony A99 does as ISO sensitivity increases -- unsurprising, since the latter is two years old and its image processing doesn't benefit from a couple years of fine tuning. I like the more neutral white balance of the Sony's default profile, though; Nikon's is just a hair shifted toward red/blue. And while the D810 maintains sharpness and tonal range better across the sensitivity range, for about $1,000 less the D750's photo quality stands up pretty well against the D810's.

JPEGs from the D750 look exceptionally clean up through ISO 1600, where a tiny bit of detail degradation begins in the in-focus areas. At ISO 3200, you can start to see some mushiness develop in the focused areas, and noise-reduction artifacts appear in the out-of-focus areas. Dynamic range displays visible decreases around ISO 3200 as well, with some clipping in low-key areas and loss of tonal distinctions in high-key areas. There's also a slight color shift between ISO 50 (Low) and ISO 100. However, I was happy with the JPEGs as high as ISO 6400 -- though that's dependent upon lighting and scene content -- and had ISO 12800 raw files that I could work with comfortably.
Movie quality looks great, even in low light, though as with the stills you start to lose tonal range about ISO 3200. Nevertheless, best quality video looks sharp, with few visible artifacts, and up to ISO 3200 there's practically no noise sparkle. I suggest switching from the default Picture Control for shooting video, though, unless you like your blacks crushed and your whites blown, even in good light.

Performance

Note: We recently updated our testing setup; though the methodology is similar the lighting conditions are not, so the results aren't comparable with previous testing. We're slowly retesting some important older products, and until we have comparable results we will not be posting performance charts.
In both lab and field testing, the D750's shooting performance fared typically for this class of camera; however, it's still really slow in Live View, and there are annoying hitches when accessing some settings.
It takes less than 0.2-second to power on, focus and shoot. Even then the bottleneck is the power switch, since you have to turn it on and press the shutter with the same finger. Single-shot performance is roughly what you'd expect for the money. In both bright and dim conditions (down to about 3 EV), time to focus and shoot runs just under 0.4-second; actual speed is a bit faster than that, since the kit lens tends to drive a little slowly. And while I didn't time it, focus down to -1 EV was is sufficiently fast and accurate as well. Both raw and JPEG take about 0.2-second between consecutive shots.
The camera excels when it comes to continuous-shooting performance, however. It bursts about 6.6fps for highest-quality JPEGs (not even the default of Normal quality) with a buffer well beyond my 30 test shots -- I got bored after 70. That sets a new high for its price class. While raw burst flies at an even faster 7fps, that's only for about 15 shots. After that it drops, though to a still-respectable 4.6fps. It manages about 10 raw+JPEG shots before slowing a lot.
Equally important, the autofocus seems reasonably able to keep up with the continuous shooting; my hit rate of usable shots using the new Group AF was significantly better than Nikon's various tracking options, partly because in those modes you have no real control over the actual focus points it uses. (Your mileage may vary depending upon your personal shooting quirks, of course.) I do miss an option for expanded-point AF, though, which essentially uses a single focus point and only expands to a group of points for support. The single-point autofocus mode is quite accurate and quick.
Unfortunately, the D750's Live View performance remains locked in the doldrums, taking about 1.5 seconds to focus and shoot under optimal conditions.
There's also some sluggishness bringing up screen-based options. For instance, using the back LCD view to change the ISO sensitivity (the only way to see it when the camera's set on a tripod at eye level), I frequently experienced long waits. This is something that Nikon should be able to address in a firmware update, though.

Design and features

With just a couple of small exceptions, the design of the D750 has a streamlined shooting design, a comfortable, high-quality build and an almost spot-on set of features. The body incorporates magnesium alloy for the rear and top cover, but uses lighter carbon fiber for the front chassis and cover. Physically it bears a striking resemblance to the D610, with comparable weather sealing to the D810.
The design is a useful cross between the consumer and pro models. It has a deep grip with a rubberized section on the back that is perfectly sized for my hands, for whatever that's worth. In the front, accessible via the fingers of your right hand, are two programmable buttons, while the left side has the flash popup/compensation button, bracketing button and manual focus/autofocus switch, with the button that brings up autofocus mode selections. As you'd expect in this class of camera, there are front and back adjustment dials.
On the top left sit a lockable mode and release-mode dials, similar to the D610. In addition to the usual manual, semimanual and automatic modes, there's an Effects mode with a handful of basics: Night Vision (high ISO sensitivity monochrome), Color Sketch, miniature, selective color, silhouette, high key and low key. It also offers a pair of saved user settings slots on the dial.
The release-mode dial contains a full set of choices: single, continuous low and high, quiet single and continuous, mirror up, and a self-timer with options for multiple shots at various intervals.
The left top includes the power switch around the shutter button, and the metering and exposure compensation buttons. There's also a tiny, hard-to-find-by-feel record button near the power switch and the usual status LCD.
On the back you'll find the excellent viewfinder and a large tilting LCD. While I prefer a fully articulated display, this one does a full 90-degree angle facing both up and down. Down the left side of the LCD are the menu, white balance, image quality, and ISO sensitivity buttons, along with Nikon's i button. The latter provides access to context-sensitive semifrequently needed settings.

Don't confuse the i button with the info button on the right, a non-interactive view of all the current settings. A combo AE-L/AF-L button is reachable via your right thumb. There's one big issue here: you have the ability to program the function of the button as well as to assign the AF-L function to another button on the camera, just like you can on higher-end models like the D810. Unfortunately, if you reassign that button -- I like to make it AE-L only -- then you lose the ability to focus via the shutter button. That's how it works on the D810, but that camera has separate AE-L and AF-L buttons so it's not as big an issue.
The camera also has the same lockable multicontroller with center OK button as the D610. I find it as uncomfortable to use on this camera as every other Nikon that uses it. And at the bottom right is a Live View/Movie toggle switch with a Live View button to initiate it.
You'll also find a solid complement of ports on the left side: an accessory terminal for remotes and Nikon GPS unit, HDMI (supporting clean output), mic and headphone jacks and a USB 3.0 port. And on the right there are two SD card slots, which are great to have.
As for features, the D750 provides all the essentials, plus highlights like multiple exposure, intervalometer and time-lapse with exposure smoothing; orientation-linked focus points; selectable spot size for centerweighted metering plus the ability to set a permanent exposure bias for each metering mode (matrix, center-weighted, spot and highlight-weighted) in 1/6-stop steps up to 1; and 50/60Hz flicker reduction.
In addition to clean HDMI out, the D750 includes the same movie-shooting specific menu as the D810, where you can choose default Picture Control, noise reduction and ISO sensitivity settings for movies. I really wish it let you set a default shutter speed and aperture as well; two custom settings slots aren't enough to handle both still and video needs.
The camera also supports Nikon's power aperture, which lets you change the aperture via the up/down buttons on the multicontroller while recording. Power aperture does not mean silent aperture, though. I also hate that you can't change other settings while shooting. For instance, if I realize that I've got the wrong ISO sensitivity set, I don't like having to stop and jump out, possibly missing something; I'd rather change it while recording and toss the transition portion of the clip later if necessary. I also miss an autofocus sensitivity setting, a feature that Canon debuted with the 7D Mark II, to make the autofocus more usable in video.
The D750 incorporates Wi-Fi connectivity. Unfortunately, the Wi-Fi implementation is pretty weak, at least until Nikon improves its app. In its current incarnation, the app is basically a glorified remote shutter -- effectively all you can do is press the capture icon -- and utility to geotag and transfer photos to a mobile device or share them via the connectors installed on the device. (While Canon's EOS Remote software has more shooting flexibiility, at least Nikon's WMU can directly upload via installed services.)
While the software issue is resolvable, the hardware awkwardness isn't. There's no quick way to enable Wi-Fi in the camera; you have to go into the setup menu to do so, and you can't program another button as a shortcut.

Conclusion

Thus far, the D750 seems like the best overall value in the price segment between $1,800 and $3,000 (£1,300 to £2,300/AU$2,000 to $3,400); it's not cheap, but delivers the best combination of performance, image quality, features for the money.
Compared to a more expensive model like the D810, the D750 has only a few shortcomings. Its image quality isn't quite as good and the resolution isn't as high, but both may suffice for a lot of people. It also maxes out at one stop slower shutter speed (1/4,000 sec. vs. 1/8,000 sec.), and it has a lower flash sync of 1/200 vs. 1/250 sec.
But the D750 has advantages over the D810, including an updated, more low-light sensitive autofocus system (I haven't yet run performance tests on the D810) and slightly better continuous-shooting performance; built-in Wi-Fi; a tilting LCD; longer battery life; and it's smaller and lighter. It also has feature advantages over the Canon 5D Mark III, like the tilting LCD, built-in flash and Wi-Fi. (I haven't had a chance to retest the 5D Mark III for performance and image-quality comparison, however.)
The D610 currently runs about $400 (£400/AU$300) less than the D750, but that premium buys you better photo quality, newer autofocus and metering systems, slightly faster continuous shooting, 1080/60p video and clean HDMI out, a tilting LCD, built-in Wi-Fi, USB 3.0 support and better battery life. And, in fact, with a few minor exceptions it has the same body design as the D610. That's a lot more camera for a fairly modest price differential.
The Sony A99 remains a compelling alternative, especially at its lower price, but aside from being old, it doesn't have the continuous-shooting performance, and some people prefer an optical viewfinder to the Sony's electronic viewfinder. And Sony's mirrorless full-frame alternatives -- the A7 series -- just don't offer the performance of a dSLR.
