Yes, it will fit any Sony e mount body, either full frame (a7..., a9...), or aps-c (like a6500, etc) 
Q
Which M42 adapter should be used on your lens?

Please note: our M42 adapter ring could not be suitable for Pentax Takumar Super Takumar Carl Zeiss M42 series(aperture pin does not fully depress, small tabs sticking out), as ours depresses the aperture pin all the way down

Q
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.)
