They are quite good and enough for me and I use other apertures also ,-) Ah, then I misunderstood. I thought you meant that there are no or too few fast (enough) lenses for GFX.  No problem. Thinking about equivalent to 35mm, f/1.3, in the case of the GF f/1.7 lenses it's a very bright aperture, with the advantage of sharpness even at that aperture, which I can't get with my classic Zeiss, which are only sharp after they're closed. 2-3 stops (1.4/50mm and 1.4/85mm). After all, this topic is about adapted lenses ,-) So some adapt better than others. Not to mention the vignette, which can be residual or very strong, for example between the Planar 85mm and the Distagon 21mm.
My point is; is it worth keeping these Zeiss (21/35/50/85), since the GFs are superior, have no compromises and are already as bright as some of these Zeiss? The difference and the biggest impediment is the price ,-) But the return is quality and satisfaction without compromises. Only you can decide! Personally I'm keeping the 50 (but I also have a Sony FF to use it with). However, performance wise I havent' tried any shortish lens that is even close (edit: on GFX) to the GF lenses. And performance is the main reason I shoot GFX, so...
Depending on what and how you shoot, the 85 can be nice. It has very little vignetting, but some curvature of field and astigmatism outside the middle of the frame. I found I wanted to stop it down to f/2.4 too, which made it kind of pointless. So I sold it. That's right.
For me it is a problem between the rational and the non-rational. I've had these lenses for many years with joy and I even like them as industrial design objects, but... Now that I'm on the GFX50R system, I have serious doubts. I have no other system. Maybe I'll still do a final test, which doesn't solve either the vignette, or the lack of sharpness of some of them, which is to use the new GFX50S II with IBIS to see if it improves the use especially of the 85mm that is the heaviest.
Of course, the matter for me is even more nebulous, because I also make sometimes an unconventional use of the equipment and the limitations are absorbed. The forking paths; quoting a great author ,-)...Show more →
Don't forget that IBIS requires an even larger image circle! The sensor is "moving around" and will be outside the usual 55 mm diagonal now and then. You can end up with one black corner, which isn't very nice looking.
