Loss in sharpness on XF50-140mm after drop and repair

I just got my XF50-140mm repaired by Fujifilm in the UK after I dropped it, damaging the mount and metal around the front element. Now I'm noticing that it's no longer as sharp when I open it beyond f/5.6. I've never been able to see any sharpness difference on this lens from f/2.8 to f/8, but now there is a distinct loss in sharpness from f/5.6 to f/4 and again to f/2.8. It's more noticeable when zoomed in to 140mm, but it can be seen at 50mm too if you compare photos side-by-side.

Is this something I should have expected Fujifilm repair to discover and fix? When I sent it in I explained I had dropped it and that the mount and front metal was damaged. I know the sharpness loss was not there before the drop since I have photos, but I don't know if the loss in sharpness is due to damage from the fall, or from the repair not being properly quality tested.

What should I do? Can I request that Fujifilm fix this? Should they have picked up on this during the repair?

Another factor in this is that due to Brexit it took over four months to get the lens repaired. It was stuck in UK customs both on the way to the UK (from Sweden) and on the way back. I really don't want to have to send it in again and get it back in September or October.

      Looking for Full Frame lenses to adapt to GFX

      By Giampaolo Masserano · Posted

      I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.

      I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results.

      Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.

      Jerry Thank you very much. That is extremely helpful. It seems that the camera and the lens have the latest firmware update, so it appears that the corrections should be applied automatically. The lens arrived this afternoon and I took some quick test shots, in which the correct lens information appeared in the EXIF files, so that sounds good. I used Adobe DNG converter to convert the Raw (RAF) files, and then opened the DNG files and saved them in PSD format. However, with a beautiful, clear, cloudless blue sky, there were no lines near the edges to check if distortion had been corrected. Another day I plan to photograph a brick wall. Thank you for your help.
