AF would be a very fancy adapter indeed - they lenses are driven by the body. Not impossible but way more difficult.Thanks but I did see those already. I was hoping to find something that allowed me to use my newer model Blue Rings and get apeture control and AF. Tall order I know.
Only the older manual Mamiya lenses I believe have manual aperture control - all digital in the newer stuff.Re. Aperture control, do the lenses have a lever at the back so the body can physically move the aperture or is it purely an electronic connection? If the former, then an adapter along the lines of the Fotodiox one allowing use of Pentax 645 lenses (including those with no aperture ring) is theoretically possible.
I looked at a few online and I'm not seeing an aperture control lever like the ones in Pentax 645 lenses.
Fuji makes an adapter for H lenses to GFX, but I'm guessing that's because they made those H lenses.
I think it is just too small of a market. Most of these 3rd party adaptors do not license anything, they just reverse engineer the communication and mount specs.If Kipon ever makes such an adapter I'd be a happy camper. However, I'm not sure if I've ever seen a third party product for Phase One before. Could be that it's just too small a market or that Phase make it difficult.
I don't think this is the case as there is the Mamiya/Schneider adapters from Kipon - TLDR: the 100 dollar more expensive one works with the newer lenses, and the less expensive one works with older lens.Fringer makes an adapter for Contax 645 lenses to Fuji GFX, an even smaller market. I'm sure there must be something about Phase One that inhibits the production of an adapter.
