Curious which adapter is more popular and which mount has more adaptable lenses for the GF? I've been a Nikon shooter so the F mount is well known, but I hear amazing things about adapting some lenses like the 200mm f/2. I really want to mount the Sigma 105 1.4, because I hear/seen that its absolutely stellar. Thank you for all/any suggestions
I have no ecperience with F-mount, but the Fringer EF-GFX pro works great with EF glass and provides decent to great AF (in terms of GFX technology).
And the Sigma 105 1.4 is indeed awesome, but an absolute monster in terms of size and weight....same with the Sigma 50 and 135 lenses.
On the other hand the Canon 40mm 2.8 pancake lens is a very small and light (in GFX terms again) option as a walk around lens.
