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.”

Product Description

The Sony Alpha 7 is a full-frame E-mount mirrorless camera. The A7 is very similar to its more expensive sibling (the A7R), except that it uses a 24 megapixel CMOS sensor with on-chip phase detection. The A7 twins are the smallest and lightest full-frame cameras on the market.

While the cameras can use any E-mount lens, there will be a crop factor involved (unless you don't mind vignetting). Sony is producing a new line of FE-series lenses that take advantage of the larger sensor.

The A7's use the new Sony Bionz X processor, which produces images with better detail, less noise, and reduced diffraction. Other features include a 3-inch, tilting LCD, XGA OLED electronic viewfinder, Multi-interface (hot) shoe, Wi-Fi with NFC, and 1080/60p video recording.

Overall Score

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.

Good For

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

    Hands-on Sony A7 Kit impressions

    Today i had a chance to play with the Sony A7 coupled with the 28-70mm kit lens for about an hour and a half. They didn't have the LA-EA4 adapter, so i couldn't test it with my alpha lenses. What i liked and surprised me even after reading and watching numerous previews: - superb image quality, even at really high ISO settings - the camera is small and incredibly light, even comparable to my Lumix LX5 with a wide angle lens attached - speedy and accurate focus - great customisation options ...

    Sony A7 review from a non-pro

    Hey, So far I've seen a lot of professional and manual focus experts trying the camera and give very useful insights, however I'm more of a hobbyist and enjoy new toys with autofocus, so here's my brief experience. +++ Build quality is superb, best I've seen in the mirrorless peers, more solid than RX1, E-M1. I feel it's on par with 5D Mark III and Leica M (design is subjective, just talking about build quality) ++- Shutter, few reviews mention that sound is loud and slow, I find it perfectly ...

    Ergonomics Are Key...

    I never thought I would try, let alone "enjoy" a Sony camera but these new Alphas are game changers for me. First, let me state that, for me, ergonomics are a big selling point with the compact cameras (and even DSLRs).  I've tried many and currently own a Nikon D600, Nikon Coolpix A and Fuji X100.  The ergonomics on the Alpha 7 are probably the best or at least equal to the best on any compact camera yet.  The next closest camera would be the Ricoh GR Digital (original). If you can operate, ...

    What Does the World's First Interchangeable Lens Mirrorless Camera Offer?

    We got the first A7s at our store, and I've had a little time to play around with them. I haven't done a proper photo shoot or test with them yet, but considering how much talk this camera has stirred up on the forums, I thought that some of you would appreciate hearing what info I have to give as soon as possible, so there's less talk about what-ifs. For starters, the camera feels great. I would have liked a slightly wider profile with a slightly deeper grip, but I have big hands - I'm sure ...
