Lensrentals released their test results for the Sony FE 70-200mm f/2.8 GM OSS and they are surprisingly disappointing. Up until now I have heard very good things about this lens, but Lensrentals testing is very reputable and they seemed shocked by the results too.
“If you view the charts at 100%, you’ll see that they’re consistent with the MTF charts Roger generated for all three lenses. 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.”
It’s a shame that Sony missed the mark on such an important and expensive lens and maybe there is something software wise that corrects the error, but it failed to impress even when they shot the Sony FE 70-200mm f/2.8 GM OSS with comparable 70-200’s on a Sony a7RII. If you’re as shocked as I was then go check out the full Lensrentals article here for more details.
