Fringer’s Contax 645 – GFX smart adapter
Fringer’s Contax 645 – GFX smart adapter is finally ready for demo. You can see pictures of the prototpye as well videos and samples images below. (Arca quick release compatible) tripod mount included.
“GFX50s doesn’t support PDAF while Contax 645 lenses are designed for PDAF. Thus, it is extremely difficult to let those lenses AF fast and accurately on GFX50s. Two weeks ago I thought 140/2.8 would never AF properly on GFX50s. But finally I made it work just like the 45/2.8 and 35/3.5 do. However, their AF performance will never be comparable to native G mount lenses.
I have to emphasize AF is an experimental function of the adapter, on current stage at least. Don’t expect them perform like on a SLR. If AF performance can’t satisfy you, MF is always available. In the future, maybe a GFX body with PDAF support will come out and finally save us.
So far I only have one prototype in hand. In a month or so there will be a small batch of products ready for beta tests. Thus, don’t ask me where to buy it now.
Following test shots were all taken by myself with AF on.”
Below you can see the prototype, the demo video as well as some sample images.
