Sony FE 100-400mm f/4.5-5.6 GM OSS Review by Photographylife

Honestly, the Sony 100-400mm GM lens is a marvelous lens that in my opinion is better than its Canon counterpart. Sharpness is fantastic, focus speed and accuracy is phenomenal when paired with the Sony A9, and overall handling is very good. The only gripe I have with the lens is the weather sealing which is not up to par with Canon lenses. I had some issues with condensation building up inside the lens during high humidity situations when my Canon lenses had none. Hope Sony do something about their weather sealing…
