100-400mm GM vs 70-200 GM vs 70-300

With all that Sony A9 news storm we didn’t report much about the new 100-400mm FE GM lens. You can play around with the lens size comparisons at Camerasize. And Jason Lanier posted his 100-400mm FE lens hands-on video.

From what I heard from the early Sony testers the Lens Image Quality is great and more importantly the autofocus with the A9 is super fast:

Re: Sony 100-400 GM with a9, focusing is basically perfect at 400mm even in dim light (1/4000, f/5.6, ISO 25,600) 👏
