question
If a 200mm 645 lens (original manual focus) is mounted on a Canon 5D II what magnification (or reduction) will result?
There is a crop factor of .78 so a 200mm 645 lens on a full frame 35mm DSLR is going to be around 256mm.

question
Hi, does this adapter allow me to control the lens aperture on Pentax 645 FA and D-FA lenses.I cannot quite see by the photos if this is possible.I assume that you can turn the outside of the adapter to adjust the aperture.Please confirm.Many thanks, Scott
When using the FotodioX Pentax 645 Pro Lens Adapter for Canon EF-Mount cameras, if the lens has an aperture ring, you can adjust the aperture manually.

Re: FotodioX Pro Lens Mount Adapter for Pentax 645 Lens to Canon EFJust wondering, anyone know how well this this adapter fits the Pentax lenses? I bought a different brand from a local dealer, but the slightest touch of the release button and the lens comes off!I'd like to know if the FotodioX one is more secure.Thanks.
It works perfectly. I'm happy with it it.
