FotodioxPro Lens Mount Adapter Compatible with Arri PL Lenses to Fujifilm GFX G-mount Cameras

Finalmente puedo usar mis objetivos Mamiya 645 con mi cámara digital de formato medio con resultados sobresalientes. Muy buena compra. Muy recomendable.

Trop cher mais fonctionne bien.

Does not work on My GFX 50R - are there any special instructions? - none came with the unit

I use this with a Pentax 80-160mm lens (for the 645Z) on my Fujifilm GFX 50S. The fit at both the lens and body end feels solid - no wiggle. I haven't noticed any change in effective focal length or light transmission, but I haven't honestly tested for this - it is just my feeling from having been using it for a couple months or so.Keep in mind that you will lose both auto focus and auto aperture control. In fact, no aperture information is provided to the body at all, so the data on all of your image files will show either f/0 or f/1. If you think you will need to know your aperture setting later on, you'll need to make a record of it yourself.Also, to manually set your aperture, you'll need to adjust your lens' aperture ring AND the aperture ring on the adapter. At least that is what my quick testing has shown. If you forget one or the other, you'll likely get an unwanted exposure.In the end, I'm just glad to be able to continue to use a lens for which Fuji has no alternative.
