Hi all, long time forum lurker here. Just jumping in because I'm considering this or the 50/3.5 or 63/2.8 as my first Fuji GF lens (hitherto been shooting GFX using Pentax-A 645 35/55/75/120 and Tamron VC 35/45 lenses).
In particular what concerns me is transition zone smoothness. Sample images showing background bokeh are not hard to come by, so I'm not bothered about that - and it's clear the 55/1.7 does well in this regard.
Would anyone who owns the 55/1.7 and one or both of the 50/3.5 and 63/2.8 be up for posting some transition zone comparisons?
Cheers,
Chris.
At what distance and aperture do you want to compare them? I'll see what I can do, but it's usually a lot more work than anticipated.

Which camera body? I shoot mostly 80mm f1.7 @f1.7/f2 and no major issues on GFX100s. But then my models aren't moving like my kids.
It is probably mostly due to technique, not camera (gfx50s2). Camera focuses, but DoF is very thin, tiny movement and it is off, enough to get it wrong.

Come to think about it, even on 3/4 portrait the smallest dot covers eyebrows and eye. It is probably quite random where focus land, but the difference is visible. I imagine a great eye detection would help with it, and gfx50s2 is not it.

How does this sound?
Aperture: F3.5
Distance: 70 or 80cm, maybe a touch longer, should be enough to produce distinct falloff with the 50/3.5. Then to keep the frame and severity of the falloff very very roughly similar, pull back about 10cm with the 55/1.7 and then same again with the 63/2.8, whatever looks 'right' to you. Remembering its a qualitative test, not quantitative.
If you can try to include both background and foreground falloff in the frame that'd be very helpful. One of the things I think I've picked up on from 55/1.7 sample images is much worse bokeh in the foreground/front transition. Maybe viewing from a 30° angle along the length of a gnarly tree or branch, lots of chances for ugliness.
If you can be bothered you could always take an extra shot at f2.8 with both the 55 and 60.
Thanks for posting these. I'm still not convinced, in particular by the foreground transition. Those are very smooth regular surfaces and they are still ending up a bit shakey looking, for want of a better description. The thumb grip/protrusion area on the second image of the camera really sticks out to me.

I'd love to see a photo of a person (or other subject) at mid-distance with some separation from the background with the 55mm at f/1.7. Any takers??
Somehow, with gf55mm I catch heavy moire pattern on almost all clothing. Either it is my recent luck, or this lens needs to be dedicated to nudes, or shooting wide open and very out of focus! It is way too harsh and sharp!

It sounds like the 80, "scratchy", but not as loud and faster.
It is LOUD, at least compared to 45-100mm or 110mm, but both of those sport linear motors. 45-100mm is still much quieter than 110mm, the 110mm sounds like rubber screaming. But still, 55mm is a quite louder than 110mm.
But oh boy the lens if otherwise wonderful! Have had it only a couple of hours, and haven't yet had an opportunity to properly test it outside, but oh it's creamy even in low light inside
I have the Sigma 50f1.4 art lens in canon mount and using the fringer adapter I compared it to the 55f1.7. The sigma is soft in the center until about f2 and then it seems close to the 55 at most aperatures in the center. On the edges the 50 has quite a bit of smearing and fringing, and doesn't transition (dof/out of focus areas) fall off as well. I think if you shot the sigma 50 in 35mm mode you might be ok but I'm really happy to see the performance of the 55mm which performs really nicely from edge to edge.
I think it is better to compare 55mm f1.7 to the Sigma 40mm f1.4 art. But good to know that 55mm f1.7 is nice.
People mentioned noise of different lenses. When I am shooting (outdoor or the studio) I never ever noticed any noise problems. I am mainly single shot mode. No video. The only lens where I know it made some noise was Fuji XF 35mm f1.4. But I still liked it.
Did anybody notice a startup delay with gfx50s2 with mounted gf55? My camera turns on but none of the dials work including aperture ring for about 10-15 seconds. It works fine after this initial delay. It does not happen with other lenses afaik.
