DxOMark tests the new Sony 70-200mm f/4 G FE lens on the A7r and finds that it performs well against the competition. This lens would also work great with the fast autofocus of the Sony A6000 with an equivalent field of view of 135-300mm on the aps-c sensor.
From the DxOMark review:
The Sony’s performance is very good and sharpness levels are very high, and even though it can’t quite match the best in class – the Nikkor 70-200mm f4 - at 200mm, it’s still unlikely to disappoint. Coming bundled with a tripod collar, the Sony even slightly undercuts the rival Nikkor model, making the FE 70-200mm f4G OSS look good value without compromising on quality or practical features.
