IMAGE QUALITY & PERFORMANCE - SONY A7R II
The A7R II’s autofocus (AF) system is much improved, with on-sensor phase detection for faster AF performance and a total of 399 phasedetect autofocus points spread across the frame. Needless to say, the AF performance was right up there with the rest, and the camera itself was certainly a speedy performer. One thing we did notice was that in very bright daylight the electronic viewfinder seemed to a bit lacking comparing to the traditional optical viewfinders on the other two in terms of the brightness and contrast needed to reflect the details in the scene accurately. In terms of resolution though, we’d say the A7R II is right up there with the 5DS R, with the 5-axis stabilization coming in handy at slower shutter speeds. One thing we did notice though is that the camera seemed to turn in images that were slightly bluish, meaning you’ll have to apply a bit of color correction to be accurate.
If you absolutely must, the A7R II will get you night shots the others can’t, at the cost of an abundance of color noise. We’d stop at around ISO 12,800.
The A7R II’s images have slight tinge of blue compared to the others.
