With the Sony α7 series Sony began to focus its Sony α system away from cameras with Minolta AF mount to mirrorless CSC cameras with Sony E-mount. The α7 series got the FE-mount variant which supports the new full-frame E-mount lenses. Thus the α7 where Sony's first CSCs with 35mm full-frame image sensor. With the Sony α7 II the move of the system's focus was finished by adding a 5-axis sensor shift, making it the first E-mount camera with anti-shake mechanism, a superior one compared to the "super steady shot" of the A-mount DSLRs and SLTs.

The Sony α7 was the quantum leap in digital photography, by having made a compact mirrorless digital system camera (CSC) capable to shoot "full format" what means a digital frame format equal to the quite ideal former miniature format, better known as 35mm film 24×36mm frame format. Before the α7's launch in 2013 this format was only available in bulky DSLRs, in professional camcorders and in the expensive Leica M9. The CSC has a full format Sony CMOS 24 megapixel image sensor, and a built-in electronic viewfinder. Its retro style housing resembles a Minolta XE. Thus Sony finally embraced the Minolta legacy that it represents since it took over all system camera production assets of Konica Minolta in 2006.

The variant Sony α7S has a 12 megapixel full format sensor and 4K-video-format support. With less but larger pixels it is the low-light queen of Sony's cameras, allowing to shoot autofocus exposures and videos in almost dark places.

Sony α7 II
The Sony α7, but mightily reworked, for example with tiltable monitor instead of a fixed one. Thus it's not as light and slim as the 1st version. Long expected and finally delivered was the anti-shake mechanism, a 5-axis sensor-shift system.
