a7RII Reasons to buy
State-of-the-art sensor and autofocus
While we’re yet to see for ourselves, the a7R II’s 42MP BSI-CMOS sensor sounds promising. Perhaps more exciting is its Hybrid AF system which has 399 on-sensor phase detect points that cover 45% of the total frame. You’ll be able to take advantage of the speed and tracking abilities of the system on third party lenses as well, using the appropriate adapters.
5-axis Image Stabilization
As with the a7 II, the a7R II offers sensor-shift image stabilization that corrects for translation, roll, yaw, and pitch movement.
Sony has doubled-down on reducing shutter-induced vibration on the Sony a7R II. The new shutter mechanism reduces vibration by 50%, and the electronic first curtain eliminates it entirely – and allows for silent shooting
a7rii 4K Video
The Alpha 7R II reads out its whole sensor to capture 4K video in either full-frame or Super 35 format with a full suite of manual controls as well as headphone and mic jacks. Phase-detection makes for usable AF in video.
