Lensrentals tested the 70-200mm GM lens and the bad news is that it seemd to not have the expected top-notch quality:
The Sony just isn’t that great, and that’s really disappointing considering the price tag and how long customers have had to wait for that lens to be available. But if you need f/2.8 and working autofocus, it’s really the best option out there for Sony mirrorless cameras.
Not that Tony Northrup is testing the lens too and said the lens performance is “stellar”. So let’s wait and see a couple of more reviews. Anyway, if f/2.8 isn’t absolutely necessary save the money and get the excellent 70-200mm f/4.0 FE lens which just got tested by Hugh Brownstone:
