Why FF lenses will be faster in AF? I always thinking it have slightly bigger and heavier glasses, which is harder to move for focusing and thus it should be a bit slower.

P. S. Very interesting rating, because Sigma 60 2.8 I could get here used only for $100, compared to $320 for Sigma 56 1.4 and $200 for Sony 50 1.8 also used.

I don’t know if I could come to a conclusion on this with only one lens. But my 50/1.8 OSS was slow to focus and thus I ended up trading it in for the Sony Zeiss Sonnar 55/1.8 which is a FF lens. The Sonnar focuses fast and it is clearly my fastest lens when it comes to focusing. Not only I use it for model shoots but also for sports and indoor entertainment.
