what is the crop factor? in other words, what is the 50mm lens equivalent in 35mm full frame (what is the normal lens)?
Asked by: Anonymous
For all Pentax 645AF2, 645AF and 645A lens you mount to this camera youll multiply the given focal length by 0.79 to calculate the 35mm-equivalent focal length. As such, a 50mm lens on the Pentax 645Z Medium Format DSLR Camera would be the equivalent of a 39.5mm lens on a 35mm film camera.

Asked by: Anonymous
In order to mount Pentax 67 series leaf shutter lenses onto the 645Z, you will need an adapter such as the FotodioX Pro Lens Mount Adapter for Pentax 67 Lens to Pentax 645 Mount Camera B&H # FOPP645AP67. Please see the image below for reference.
