Does this adapter allow for canon fd lenses to focus to infinity on sony e-mount mirrorless cameras?

yes, i had no problems with infinity focus with this adapter. the only FD mount lens i use anymore with my sony is a vivitar 20mm, and i pretty much only shoot infinity focus with it. 
Q
I currently own 3 a-mount lense (from a sony a230) just bought a sony a5000, which is an emount. Will this adapter fit my old lenses to my new camera?
A
No, this adapter is for the older manual focus Minolta Rokkor MC and MD lenses. If you want to autofocus and aperture control you will need the Sony LA-EA4. (the lower cost Sony LA-EA3 will electronically connect A mount lenses but you will have to manually focus.)
