Every week a new video showing the focus speed of the Sony a7RII comes to light, and this week it’s the Sony A7RII Autofocus Test With Canon 70-200mm f/4L vs the Sony FE 70-200, thanks to Cameraegg.com.
The website found these videos of a user in China using the Sony a7RII with the Sony A-mount 70-200 f/2.8 and the Canon EF 70-200mm f/4L IS USM. They also seem to have to have gotten their hands on the rumored Nikon F-mount to Sony E-mount adapter, which they confirm will be announced soon. (Editor’s note: That seems pretty convenient.)
Sony a7RII tested w/ FE 70-200mm f/4 G OSS lens: AF speed is very fast.
Sony a7RII tested w/ A-mount 70-200mm f/2.8 G SSM II lensuse LA-EA3 adapter: The AF speed is almost same as use FE 70-200mm f/4 G OSS lens.
When testing Eye Tracking AF on a7RII, the tester said it works very well.
A read asked high ISO performance on a7RII, the reviewer replied: “Depending on the firmware version is too low, the testers were instructed not to spread a high sense of evaluation results, but privately say the high ISO performance is only slightly inferior to a7S, but better than a7R, 5-Axis SteadyShot INSIDE Stabilization is very good.“
