Great quality and super easy to use at an affordab
Great quality with an affordable price! It’s super easy to use too! You just remove the lens cover and click it on! It’s literally a two second set up. Many others who saw me using this have asked me for the link!

Q
will my Canon lens work with my Sony a5100 with this adapter?
A
Don’t forget that it’s a manual lens adapter. Works with full manual lenses. If your lens has no physical aperture ring, you cannot control it from your camera  
Q
Will this adapter work with the canon eos-r?
A
no it will not the eos-r has a different mount 
Q
Does this stop at infinity or does it focus past infinity? I need a simple infinity only adapter.
A
This has no focusing capability. That said it will allow your lens to infinity focus the same way as it did on its original mount. It won’t change that. The only issue I can imagine is the quality control issue if any from adapter to adapter, manufacturer to manufacturer. Basically if your lens goes past infinity then it won’t change anything with it mounted on this adapter or any other 
Q
Which M42 adapter should be used on your lens?
A

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?
A
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.
