I have a Zeiss Batis 85mm f/1.8 so I wasn't sure if it was a necessary addition. I've also heard some complaints about autofocus noise. But after seeing some amazing sample images I decided to give it a try. As with the Sony 24-70 f/2.8 GM lens, the image quality of the 85mm GM is incredible. Amazingly sharp and beautiful rendering. Two questions that may arise: 1. Is autofocus noise a problem? In my opinion no, absolutely not. Based on some other comments I was expecting something loud and distracting. You can hear it, but it sounds like the autofocus system is a little louder than average. I don't think it ever occurred to me to worry about that. 2. How does it compare to the Zeiss Batis 85mm f/1.8? In terms of overall quality, they are very close. Both produce exceptionally beautiful images. The Batis is smaller and the autofocus is quiet. The colors on the batis tend to be bluish, but this can easily be corrected when editing. There's image stabilization, but it's not as critical on Sony cameras as the body itself is stabilized. It's also $600 less than GM. You will not be disappointed with Batis. However, the Sony 85mm GM is the choice if you want the absolute best the system has to offer. I've been in many situations where the extra light from an f/1.4 lens made a difference. The aperture ring is very nice. The GM has 11 aperture blades instead of the Batis' 9, resulting in a more pleasing defocus effect. For portraits, I prefer warmer colors before processing. And in my opinion it is sharper than batis. Would highly recommend this lens. This is the reason to buy a Sony A7 series camera.
