Review summary from DPReview

DPReview Silver AwardJanuary 2014
Ultimately, the Alpha 7 is a nice step-up for current NEX owners, and will certainly tempt those who want something smaller than conventional full-frame cameras.
Jeff KellerJeff KellerRichard ButlerRichard Butler
80%

Conclusion

The Alpha 7 has broken new ground in the full-frame market, in terms of both size and price. Its compact size, broad feature set and very good raw image quality make it a compelling option for those wanting a large sensor. Unfortunately, the JPEGs have many issues, performance and battery life could be better, and the controls would benefit from a rethink.

Reasons to buy

  • Very good image quality when shooting Raw
  • Compatible with a huge range of legacy 35mm camera lenses
  • Good video quality and features: manual controls, audio level adjustment, and uncompressed HDMI output
  • Large, high resolution electronic viewfinder
  • Built-in Wi-Fi/NFC allows for remote shooting, photo sharing

Things to consider

  • JPEG quality disappointing compared to peers
  • Autofocus can be hesitant, especially in low light
  • Auto ISO tends to keep shutter speed at 1/60 sec
  • Limited selection of FE lenses
  • Lacks a built-in flash

Suggested for

Those seeking a full-frame sensor in a small body, determined third-party and historic lens owners, video enthusiasts, and social media mavens

Not suggested for

JPEG shooters, Auto ISO users, and photographers who want to quickly capture a moment

Technology



World's smallest and lightest1 interchangeable lens full-frame camera

Sony's Exmor® image sensor takes full advantage of the Full-frame format, but in a camera body less than half the size and weight of a full-frame DSLR.

Full Frame 24.3 MP resolution with 14-bit RAW output

A whole new world of high-quality images are realized through the 24.3 MP effective 35 mm full-frame sensor, a normal sensor range of ISO 100 – 25600, and a sophisticated balance of high resolving power, gradation and low noise. The BIONZ® X image processor enables up to 5 fps high-speed continuous shooting and 14-bit RAW image data recording.

Fast Intelligent AF for responsive,
accurate, and greater operability with
full frame sensor

The high-speed image processing engine and improved algorithms combine with optimized image sensor read-out speed to achieve ultra high-speed AF despite the use of a full-frame sensor.


Fully compatible with Sony's E-mount lens system and new full-frame lenses

To take advantage of the lightweight on-the-go body, the α7-series of full frame compact interchangeable lens digital cameras is fully compatible with Sony's E-mount lens system and expanded line of E-mount compact and lightweight full-frame lenses from Carl Zeiss® and Sony's premier G-series.

Simple connectivity to smartphones via
Wi-Fi® or NFC

Connectivity with smartphones for One-touch sharing/One-touch remote has been simplified with Wi-Fi®/NFC control. In addition to Wi-Fi support for connecting to smartphones, the α7 also supports NFC (near field communication) providing "one touch connection" convenience when transferring images to Android™ smartphones and tablets. Users need only touch devices to connect; no complex set-up is required. Moreover, when using Smart Remote Control — a feature that allows shutter release to be controlled by a smartphone — connection to the smartphone can be established by simply touching compatible devices.




PlayMemories™ Camera Apps allows feature upgrades

Personalize your camera by adding new features of your choice with PlayMemories™ Camera Apps. Find apps to fit your shooting style from portraits, detailed close-ups, sports, time lapse, motion shot and much more. Use apps that shoot, share and save photos using Wi-Fi that make it easy to control and view your camera from smartphone, and post photos directly to Facebook or backup images to the cloud without connecting to a computer11.


Additional Features


Fast Hybrid AF w/ phase-detection for DSLR-like focusing speed

Enhanced Fast Hybrid auto focus combines speedy phase-detection AF with highly accurate contrast-detection AF, which has been accelerated through a new Spatial Object Detection algorithm, to achieve among the fastest autofocusing performance of any full-frame camera. First, phase-detection AF with 117 densely placed phase-detection AF points2 swiftly and efficiently moves the lens to bring the subject nearly into focus. Then contrast-detection AF with wide AF coverage fine-tunes the focusing in the blink of an eye.

New Eye AF control

Even when capturing a subject partially turned away from the camera with a shallow depth of field, the face will be sharply focused thanks to extremely accurate eye detection that can prioritize a single pupil. A green frame appears over the prioritized eye when focus has been achieved for easy confirmation. Eye AF can be used when the function is assigned to a customizable button, allowing users to instantly activate it depending on the scene.

High contrast 2.4M dot OLED EVF for eye-level framing

View every scene in rich detail with the XGA OLED Tru-Finder, which features OLED improvements and the same 3-lens optical system used in the flagship α99. The viewfinder faithfully displays what will appear in your recording, including the effects of your camera settings, so you can accurately monitor the results. You'll enjoy rich tonal gradations and 3 times the contrast of the α99. High-end features like 100% frame coverage and a wide viewing angle are also provided.

3.0" 921k dot LCD tilts for high and low angle framing

The tiltable 3.0" (921k dots) Xtra Fine™ LCD Display makes it easy to photograph over crowds or low to capture pets eye to eye by swinging up approx. 84° and down approx. 45°. Easily scroll through menus and preview life thanks to WhiteMagic™ technology that dramatically increases visibility in bright daylight. The large display delivers brilliant-quality still images and movies while enabling easy focusing operation.

PC control w/ remote video capture control

Remote Camera Control allows you to control your α7 from your PC using a USB cable. Feature control has also been updated to include video capture control.

14-bit RAW output for rich tonal gradation

14-bit RAW image data of extremely high quality is outputted by the α7. This data fully preserves the rich detail generated by the image sensor during the 14-bit A/D conversion process. When developed with Sony's Image Data Converter RAW development software, these images deliver the superb photographic expression and rich gradation that only 14-bit data can offer.

New BIONZ X® image processing engine

Sony proudly introduces the new BIONZ® X image processing engine, which faithfully reproduces textures and details in real time, as seen by the naked eye, via extra high-speed processing capabilities. Together with front-end LSI (large scale integration) that accelerates processing in the earliest stages, it enables more natural details, more realistic images, richer tonal gradations and lower noise whether you shoot still images or movies.

Full HD movie2 at 24p/60i/60p w/uncompressed HDMI® output

Capture Full 1920 x 1080 HD uncompressed clean-screen video files to external recording devices via an HDMI® connection in 60p and 60i frame-rates. Selectable in-camera AVCHD™ codec frames rates include super-smooth 60p, standard 60i or cinematic 24p. MP4 codec is also available for smaller files for easier upload to the web.

Up to 5 fps shooting to capture the decisive moment

When your subject is moving fast, you can capture the decisive moment with clarity and precision by shooting at speeds up to 5 frames per second. New faster, more accurate AF tracking, made possible by Fast Hybrid AF, uses powerful predictive algorithms and subject recognition technology to track every move with greater speed and precision.

Multi-interface Shoe for flash and microphone flexibility

Unlike conventional cameras, the α7 features the advanced Multi-Interface Shoe that dramatically expands compatibility with Sony digital imaging accessories, thus raising the potential for photo/movie shooting.

4K Still image output by HDMI®8 or Wi-Fi® for viewing on 4K TVs

Enjoy Ultra High Definition slide shows directly from the camera to a compatible 4K television. The α7 converts images for optimized 4K image size playback (8MP). Enjoy expressive rich colors and amazing detail like never before. Images can be viewed via an optional HDMI or Wi-Fi.

TRILUMINOUS™ color outputs wider color gamut to compatible devices

TRILUMINOS Color technology, allows you to experience photos and movies in rich, natural colors on any TV equipped with a TRILUMINOS Display. The expanded color gamut immerses you in those unforgettably colorful moments, from the complex shades in a shimmering blue sky to the delicate skin in a baby's face.

Image Data Converter

Advanced features enable manipulation, conversion and management of full-resolution RAW images. You can expertly adjust exposure, white balance, tonal curves, saturation, contrast, hue and sharpness — as well as apply DRO and vignetting compensation. Bundled Remote Camera Control software also lets you remotely activate and deactivate still/movie recording and control various camera settings from a PC.

Vertical Grip Capable

Enjoy long hours of comfortable operation in the vertical orientation with this sure vertical grip, which can hold two batteries for longer shooting and features dust and moisture protection.

Mount Adaptors

Both of these 35mm full-frame compatible adaptors let you mount the α7-series with any A-mount lens. The LA-EA4 additionally features a built-in AF motor, aperture-drive mechanism and Translucent Mirror Technology to enable continuous phase-detection AF. Both adaptors also feature a tripod hole that allows mounting of a tripod to support large A-mount lenses.

I have an adapter for Nikon lenses, and love using them on the camera.
T. Hosford
Which is why I really value how the camera feels when I am using it, the more comfortable you are with the camera, the better your pictures will likely be.
Uncle J
The question might be better answered that the A7 is not a do-all, perfect solution for everyone camera.

Style Name: 24.3 MP Body
I picked up my a7 directly from the Sony Store on November 15th in Hong Kong. The first one I received was okay except it had a mushy delete/c3 button (it didn’t click when pressed), so I refused it and had to wait until the next day to get another one. The second body had all buttons and dials working properly, so I took it home with a giant smile on my face. I purchased the camera, body only. I also purchased the Zeiss 35mm F 2.8.

Why I chose the a7 over the a7R.
1. It has less megapixels. Yes, you read correctly. 99.9% of the photos I take live in iPhoto. The only thing 36mp does compared to 24mp is take up more drive space. Also, I have a 20” x 30” blown up photo in my living room that I took on my old 12mp D300 and it looks amazing. So, 24mp is way more than enough for me.
2. It has Phase Detection Auto focus (PDAF), and the a7R does not. I wanted this faster focus because I will mainly use this for photographing my 6-month old growing up.
3. It has the low pass filter. I don’t want to have to remove moiré in photoshop or GIMP. I don’t even want to deal with photoshop or GIMP except for maybe that .1% of photos that don’t live in iPhoto. Also, this camera is also the home camcorder, and it is very difficult to remove moiré from video. (however, from test shots I have been seeing, the a7r doesn’t appear to have significant moiré problems, so this may not be all that important.)

Now that you understand where I am coming from, here is my review.

This is by far the best camera I have ever owned. Just in case you got here by accident, this is the smallest and lightest full frame changeable lens digital camera ever made.

Style Name: 24.3 MP Kit with 28-70mm Lens
There are many excellent reviews on here, so I thougt I would focus (no pun intended) on how to get good inexpensive lenses for the camera that will make it shine and give you a well rounded start at your kit without leaving you begging for food on the freeway exit ramp. I purchased the A7K (the one with the 28-70 kit lens). I do semi-pro work with photography and videography. I know good glass, but on the photography side have elected to stay away from the larger 5D MIII AND D800(E) cameras ... Just wanted to be more portable and stealthy in my street photography. I own a Sony RX1 with a DXO RATING OF 93 on the that sensor coupled with the excellent Zeiss f2.0. The sensor on the A7K has a DXO rating of 90 so it's a little less than the RX1. That's not to say the A7 is not sharp ... It is very, very sharp ... Just not with the kit lens.

So ... I took my excellent Sigma 30mm f2.8 from my Nex 6 and removed the baffle ( a common mod since then the Sigma can cover full frame). And there is a very, very tiny amount of vignetting at f2.8 and is actually very good up to around f4. All the vignetting is so light it can easily be removed in Lightroom. But that lense is absolutely tack sharp in the IQ department. Check all the reviews ... This is a $199 lens that rivals the new Sony FE 35mm f2.8 at a fourth of the cost (with the baffle removed ... 3 tiny screws and 3 minutes of work).

Then I researched and got the Samyang 14mm f2.8 super wide. This lense retails for around $348 on amazon, and has been tested by different mags and dozens of reviews to be practically equivalent to a $1400 super wide. You can get this lens under the Rokinon branding. The only thing is, of course, is that you have to use this lense with an adaptor to the e-mount.

Style Name: 24.3 MP Body Verified Purchase
As an enthusiast photographer, that I am, I wanted to give a review from that perspective rather than a more technical perspective from , perhaps, a professional, which I am not capable of doing just yet

Upon opening the box for the first time, I was immediately struck by the small form factor (and somewhat retro look - but just my opinion) and light-weight of the camera body. Indeed, I wasn't sure, at first, there was my camera inside the Amazon box UPS handed to me upon delivery (and UPS will require your signature for this item. Otherwise they are going to leave with nothing and come back another day).

This camera body looks sharp. It's not completely magnesium metal body like its A7R higher priced sibling, but, rather, a mixture of metal and better plastics. But very hard to tell the difference. Point being, no one's going to accuse you of having anything less than a fine well-built camera. It feels good in the hand. A good grip for your right-hand. It's built like a tank. And it's weather sealed.

All the buttons are where I want them to be. Perhaps the shutter button could be a little farther forward but it should be just a matter of getting use to it. The menu system is far easier to use and navigate than on my NEX6. And the NFC between the camera and my Android phone (Galaxy S4) is fast and convenient. The remote control function works very well. Checking latency revealed a very, very slight hesitency. But so minor. You'll hardly notice it. Just a nit-pick on my part (like the shutter button-certainly no game changers).

I bought two lenses (there are only 5 of the FE lenses out as of this writing but Sony is releasing a total of 15 by 2015). The 35mm (very light) and the 55mm somewhat heavier and built well.
