According to the Sony FE 70-200mm f/2.8 GM OSS lens test results, the telephoto zoom achieved an outstanding overall score of 39 points.
Tested on the Sony A7RII full-frame mirrorless camera, the lens becomes the sharpest and best low-light zoom in DxOMark database.
The FE 70-200mm f/2.8 GM features special coatings (Nano AR and fluorine), a floating focusing system for improved AF performance. The lens offers a minimum focusing distance of just 0.96m (~3.15ft), a SSM and dual linear motors.

It is the top-performing zoom lens tested on the a7R II, as well as the fourth-sharpest full-frame E-mount lens overall among both zoom and prime lenses.
From DxOMark conclusion:
It’s not only the sharpest and best low-light zoom lens we’ve tested for the a7R II. It also outperforms many FE-mount prime lens options. Ranking as the fourth-sharpest lens we’ve tested on the a7R II. Resolution at f/2.8 is first-class between 100 and 200mm, and peak sharpness of over 80% acutance in the field occurs between f/4 and f/8 for phenomenally sharp results on the a7R II.
Costing $2,498 and coming in at 200mm in length, and weighing nearly 1.5 kg, it’s a big beast for the diminutive a7 series of mirrorless hybrid cameras. This said, it packs plenty of high-end pro features for advanced autofocus operation, image stabilization, and all-round top performance in fast-paced environments.
