Did you order native lenses too?
Also, I read somewhere that leaf shutter lenses will be good with adapter, but how does one mitigate the FP shutter of the GFX?
I have the 120 and the zoom.
I also have a Fotodiox adapter to permit me using my Canon TSE lenses on the GFX 50S.
Its my understanding that I have to pre-set the aperture via a camera that controls the aperture function on the Canon lenses. That means, for me, using the Metabones adapter to set an aperture on the lens, then move it to the GFX.
It will be interesting to see how the 24 and 17 TSE lenses look on the GFX format. I also have the 45 and 90 but they are much less dramatic. Although their shift-ability will be useful to test.
I also still have a Canon 16-35L That might be worth testing via the adapter as well.
Since I am currently using Sony A7RII with these lenses it will be useful to see differences in performance.
