Thanks for the post!
Did you end up getting it or someone else ? Does it work well?
And which lenses are recommendable for GFX that have good depth perception / POP
I've got one. AF is slow and noisy but accurate enough. It's like a 1990s screw drive AF because that's what it is. I wouldn't say any of the Pentax 645 lenses are exceptional. Most of them benefit a little from stopping down.
I like the 80-160mm f4.5, the 150-300mm f5.6 and the 120mm f4 macro. The 200mm f4 is quite small and good too.
I'm sure all the GFX lenses at equivalent focal lengths would be better.
The adapter works fine, but obviously no speed demon. Had it since it became available.
FA 75/2.8, FA 150/2.8, FA 45-85/4.5 and FA 150-300/5.6 works fine and AF with all of them is fairly similar. Great optical results from the primes, but some CA wide open in certain situations.The 45-85 is good at the wide end, but soft at the long end. 150-300 decent and not bad considering the price used and stopped down handy for landscape.
The biggest issue for the adapter is the lack of a tripod foot. With zooms like the 80-160mm f4.5 and 150-300mm f5.6 and even the 45-85mm you have a very front heavy set up. If you only intend to hand hold that may not matter, but tripod use will be very front heavy.
I wouldn't bother with the FA 45-85mm as the Fuji 35-70mm is better in every respect.
