Ken Rockwell It's sharp, focuses super fast and super close, has three focus lock buttons, has great stabilization, has a magnificent 11-blade diaphragm and has a pro-grade real manual focus ring — not an electronic simulation. [...] Bokeh is excellent. This Sony has moderate cyan/reddish-orange spherochromatism.
The Sony FE 70-200mm f/2.8 GM OSS is an impressive piece of equipment. The broader center-zone is especially outstanding when keeping in mind that the lens has been tested on a 42mp sensor. The far corners could be better at 70mm f/2.8 and 200mm f/2.8 but that's usually not an issue in real life. Lateral CAs are low. [...] The build quality is perfectly aligned to professional standards.
