If there's one thing that you can say about Sony's digital camera business, it's that they've experimented with many different concepts. From SLRs with dual autofocus systems and Translucent Mirror Technology to its NEX mirrorless line-up, Sony has gone down virtually every avenue in digital imaging. Its latest products - the Alpha 7 and Alpha 7R - may be the most exciting products to come out of the Sony labs in some time. The company has managed to create full-frame cameras which are about the same size as the Olympus OM-D E-M1. In other words, the Alpha 7s are much smaller than their full-frame interchangeable lens peers (such as Nikon's D610 and the Canon EOS 6D), an achievement made possible primarily because they're not SLRs.

In addition, Sony is also unifying the Alpha and NEX brands, so all future interchangeable lens cameras will now fall under the Alpha umbrella. Being mirrorless, the a7 would have otherwise likely been prefixed with the letters NEX.

The a7 and a7R are identical in terms of physical design, with the main differences being the sensor and autofocus system. The a7 features a full-frame 24 megapixel CMOS, while the a7R has a 36 megapixel CMOS sensor with no optical low-pass filter. The a7 uses a Hybrid AF system (with on-chip phase detection) similar to the one found on the NEX-6, while the a7R has traditional contrast detection. The a7 is also capable of electronic first curtain mode, which allows for a quieter shutter, and reduces the potential for 'shutter shock' vibration; this is absent from the A7R. Both cameras use Sony's latest Bionz X processor and also have XGA electronic viewfinders, tilting LCDs, Wi-Fi, and weatherproof bodies that resemble that of the Olympus E-M1.

As you'd expect, Sony had to come up with new lenses to take advantage of the full-frame sensors, and they'll be known as 'FE-series'. Five lenses were announced to start with (listed below), with ten more promised by 2015. Existing E-mount lenses will work, though the image will (necessarily) be cropped. If you have A-mount lenses laying around, those too will work, as long as you pick up either of Sony's full-frame-ready adapters (the LA-EA3 or LA-EA4).

Sony a7 key features

  •     24.3 megapixel full-frame CMOS sensor with OLPF
  •     E-mount with support for FE, E, and A-mount lenses (with adapter)
  •     Bionz X image processor
  •     Hybrid AF system with 25 contrast-detect and 117 phase-detect points
  •     Weather-proof alloy and composite body
  •     Multi-Interface Shoe
  •     3-inch tilting LCD with 1.23 million dots (640x480, RGBW) XGA (1024x768) electronic viewfinder
  •     Diffraction correction technology
  •     Full HD video recording at 1080/60p and 24p; uncompressed HDMI output
  •     Wi-Fi with NFC capability and downloadable apps

The a7 uses a 24.3 megapixel CMOS sensor with a low-pass filter and on-chip phase detection. This 'Hybrid AF' is supposed to result in speedier AF, supporting the camera's ability to shoot at 5 fps with continuous autofocus. The more expensive a7R, on the other hand, has a 36 megapixel sensor with no optical low-pass filter and a more conventional contrast-detect AF system.

Both the a7 and a7R can record video at 1080/60p and 24p, with manual exposure control, headphone and mic ports, an audio meter, zebra pattern, XLR support (via adapter), and live, uncompressed HDMI output.
Bionz X Processor

The company's latest processor, dubbed Bionz X for reasons that presumably made sense to someone, is considerably more powerful than the previous generation, allowing what the company says is more sophisticated processing.

Sony is being a little vague on specifics but is touting the new processor as offering 'Detail Reproduction Technology' which appears to be a more subtle and sophisticated sharpening system. The company promises less apparent emphasis on edges, giving a more convincing representation of fine detail'.

Another function promised by the Bionz X processor is 'Diffraction Reduction', in which the camera's processing attempts to correct for the softness caused by diffraction as you stop a lens' aperture down. This processing is presumably aperture-dependent and sounds similar to an element of Fujifilm's Lens Modulation Optimization system (introduced on the X100S), suggesting it's something we should expect to see become more common across brands in the coming months.

Finally, Sony says the Bionz X chip offers a more advanced version of its context-sensitive, 'area-specific noise reduction', which attempts to identify whether each area of an image represents smooth tone, textured detail or subject edges and apply different amounts of noise reduction accordingly. Later in the review, we'll show you just how well this system works, and also the problems it can create.

Style Name: SEL-2870 Zoom Lens Verified Purchase
Coming from a Sony NEX 5N background (which I still use and rate highly) I'm loving the EVF, weather-proofing and Menus of the A7. Still to decide which flash to purchase for the camera. The only thing I miss is the touch screen on the 5N for selecting a focus point, though it takes hardly anytime on the A7.

Many years ago I used to lug around a huge C*n#n T90. The A7 is tiny in comparison. In fact it is so light-though by no means cheap feeling-that taking shots single handed is not a problem with the A7. Finding the Pitch and Roll level sensors in the camera really useful too.

Sony has delivered an outstanding bit of kit, and one can only hope that the A7 gains the recognition that it richly deserves for what it is; a truly remarkable camera at an unremarkable price.

I'd just like to add how wonderful the camera is for using legacy and manual focus lenses. The A7 is a joy to use with focus peaking and Pentax/Asahi Takumar lenses with an inexpensive M42 to E-mount adapter. Likewise with Leica summarit lenses, great bang for your buck/pound. Have even started using old Minlota MD lenses with an adapter. Watch those fast legacy lens prices continue to rise as people embrace full-frame and MF with this camera.

Update after 4 months of regular use. Another major bonus of this camera is that it can be easily customised with the designated C1 and C2 buttons, and the other buttons and dials as well. Ergonomically I have found everything to be comfortable to use-it's feather-like compared to a D700-and the recent firmware version 1.2 update has reduced the camera start-up time and increased the AF performance. It would appear that Sony are committed to the FE alpha system.

It's probably worth saying that, the unloved Canon EOS M aside, there are no really bad mirrorless systems to buy into at the moment and that anyone in the market for the A7 or the A7R has probably also had a long hard look at the Fuji X series or an Olympus or Panasonic Micro 4/3 body.

It can be a tricky decision, since for most people it’s an investment in a system including lenses and other accoutrements that rapidly cost more than the body alone. An investment that might reasonably be expected to last for 5 years or more.

These other systems certainly have their attractions: The Fuji bodies have a striking retro SLR and rangefinder appeal with fast all metal prime glass purposely designed to set alight the hearts of photographers for whom a 35mm Summilux remains as dreamy as the Leica glow.

The Olympus OMD EM1 pitches in with its weather sealing, quick autofocus and that very wide range of M43 lenses, all of which are good and some of which are the equal of anything made for a competing system, full frame or not.

And yet, there is something about the final emergence of reasonably sized full frame in the digital world that feels to this old film SLR user like returning home to something sensible after a long and trying digital absence.

Getting down to brass tacks, a few pros and cons after first use.

+ Full frame at last ! No more having to multiply things by 1.3, 1.5, 1.6 or 2. DOF as she was in the 1980s when I were a lad. Stepping gently round internet flamewars about equivalence in DOF and light gathering.
+ Manual lenses a plenty of course, with adaptors at £20 a pop. Buy now before the entire stock of R, OM, FD and PK lenses is exhausted in five years time and a battered Pentax 50/1.7 is going for £200.
+ High ISO.

Style Name: Body Only
I bought into Sony's Nex system when they launched the Model 5 in 2010. At that time it was the smallest body to house a dslr sized APS-sensor. Unfortunately, the IQ of the sensor was only so-so, but was really improved with the introduction of the 5N in 2011. This model was a significant advance and was able to take the quite superb, although expensive, add-on EVF. For me this transformed how the camera handled.

Although it was often criticised, I never really had any problems with Sony's menu system, but the limitation was the 1.5x crop factor when using legacy 35mm camera lenses. This made trying to get a genuine wide angle view more problematic; even my 24mm Leica lens only behaved as a 35mm with respect to the FoV. So, like many, I dreamt of an affordable FF sensor camera, but I did not want the size and weight of a dslr and its attendant lenses, and Leica M was priced way over budget. Many thought that Sony would eventually come out with such a model, but the idea of it being similar to the Nex range, perhaps an updated Nex 7, was poo-pooed in the press in view of the E mount with its very short back lens flange to sensor distance. Well, Sony proved them all wrong when they released on to an unsuspecting market the A7 and A7R, and at the same time caught all the other camera manufacturers napping. Here, now, was an opportunity to use my prime film camera lenses, but at their native FoV.

Some good news is Sony has not forgotten its legion of Nex users. Whilst the A7 has a FF sensor, E mount lenses intended for the APS-C sensor used in all Nex models can be used with the A7, albeit with a reduced resolution of 10 megapixels. The A7 can be set to detect when an E lens is mounted and will automatically adjust the framing to APS-C size.
