SONY A7R II
The A7R II follows after the original A7R with a newer high-resolution 42.4MP sensor, and a 5-axis image stabilization built into the camera body. That new sensor makes the A7R II the highest-resolution mirrorless system camera on the market and effectively lets it leapfrog over the D810 for second place in the resolution race.
But that’s missing the point. Having probably the largest backside illuminated (BSI) CMOS sensor in the market, the A7R II gains much improved high ISO performance that simply goes beyond the competition. Where the A7R could only go up to ISO 25,600, the A7R II now boasts the ability to go up to ISO 102,400 (after boost).
Compare this to the Nikon D810A and the Canon EOS 5DS which only go up to 51,200 and 12,800 (after boost) respectively, and you certainly have to admit that Sony has probably made a smart decision in not trying to push the numbers as far as resolution goes. That’s because increasing the pixel pitch for higher resolution would probably mean a trade-off in terms of noise at higher ISOs.
The A7R II gains the same handling improvements as the A7 II, with a deeper handgrip and the slight change to the control dial layout allowing for better placement of the shutter button and the inclusion of more custom function buttons. These seemingly small changes really made a difference to the overall handling as we were able to get the camera more stable without having to fumble for the shutter button. Another welcome change would be the new electronic viewfinder, which gives a magnification of 0.78x – the highest of any full-frame camera in the market at present.
On the video front, the A7R II also gets an upgrade, now being able to record 4K (3,840 x 2,160 pixel resolution) video internally – no external recorder needed this time. No ISO limits have been placed on video recording either, so you can go up to the camera’s max ISO 102,400 and still have the benefit of 5-axis stabilization with any lens. Match that with the improved autofocus system that’s sensitive from EV-2 to EV20 and you have a highly versatile camera for both stills and video.
There’s a lock button on the mode dial that you have to depress to change modes.
