Sony Alpha 7 II

24.3MP full-frame CMOS sensor | BIONZ X image processor | 5-axis image stabilization

At the core of the a7 II is a 24.3MP full-frame CMOS sensor and Sony’s Bionz X processor. Compared to the a7, a7R, and a7S, the a7II has a slightly redesigned larger and heavier body, with a larger grip and other ergonomic refinements that should be welcomed by anyone who didn't love the operation of the original a7. The Sony a7II is the second iteration of the Sony a7 line, and it's the first full-frame mirrorless camera with in-body image stabilization (IBIS) - 5-axis, no less.

Our initial tests indicate the sensor remains largely the same from the a7, which means that it has outstanding Raw dynamic range, but lags a bit behind its peers (and siblings) at high ISO performance. Like the original a7, the a7 II features 117 phase detect and 25 contrast detect points on its CMOS sensor but Sony is claiming a 30% improvement in the a7 II's AF speed and 1.5x better tracking performance than its predecessor. Welcome additions are a number of video features handed down from the a7S, like XAVC S and S-Log2.

"In-body image stabilization moves the sensor to compensate for translational and rotational movement, as well as pitch and yaw..."

The big news is, of course, the in-body image stabilization - quite a feat when you consider the size of the sensor that is moved to compensate for translational and rotational movement, as well as pitch and yaw. IBIS can even be used to stabilize third party lenses, but which types of movement are compensated for will depend on the information communicated between the lens, adapter, and body.

We have not yet fully tested this camera, but first impressions are very positive. Rest assured, we will be updating this roundup with more information once our full set of studio and real-world tests on the a7 II are complete.
