The Pro Lens Mount Adapter Kit for Mamiya RB67 or RZ67-Series Lens to Fujifilm G-Mount Camera from FotodioX includes two adapters, one of which allows a Mamiya RB67 or RZ67-series lens to be used with a Canon EF or EF-S mount camera, while the other adapter allows a Canon EF or EF-S mount lens to be used on a Fujifilm G-mount camera. When combined, the two adapters allow a Mamiya RB67 or RZ67 lens to be used with a Fujifilm G-mount camera.

Together, as well as individually, these adapters are designed to support focusing to infinity. The FotodioX Pro Lens Mount Adapter for Mamiya RB67 or RZ67-Series Lens to Canon EF or EF-S Mount Camera and the FotodioX Pro Lens Mount Adapter for Canon EF or EF-S Mount Lens to Fujifilm G-Mount Camera are constructed with brass.

Q: 1. What is the closest focus i can get with the focus magnification? For example, 110 f2.8 or other rz lenses

A: The FotodioX Mamiya RB/RZ67 Lens to FUJIFILM G-Mount Camera Pro Lens Mount Adapter will not change the minimum focusing distance or the magnification of the lens. The adapter will just take the space that the mirror in the Mamiya camera would have.

Q: 2. Is there a correction factor for effective focal length. Does (for example) a 105 mm lens still have a 105 viewing angle? Thanks

A: The adapter itself does not change the lens. But in general a RZ/RB lens, has a factor attaching it to a Full frame or APS-C DSLR camera.Full frame DSLR with a RZ/RB lens is 2.1 times factor and than if you use it on an APS-C sensor it is another approximately 1.5 times factor.Example: 80mm RZ lens, 80 x 2.1 = 168mm lens for full frame DSLR. And for APS-C, 168 x 1.5 = 252mm lens.
