Simply Works

I'm using this adapter with Pentax 645 lenses on a Blackmagic 6k camera with EF mount. Works very well. Snug fit on both lens and camera ends. This adapter allows me to use the aperture ring on the lens to change aperture.

Most cost effective thing I've bought.

Well engineered adapter. DHL/Australia post delivery efficient. I use the adapter with Pentax 645 lenses, and in conjunction with a 645 lens reversing ring I use it on a Sinar Norma technical camera with Schneider Kreuznach lenses.

A beautifully-made product

question

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

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.

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.
