Thanks, will check those out.

I wonder if its a good idea to start some kind of official lens review here on this forum group, following a similar format to PF? Could be a great resource and strengthen the Fuji brand.

Although I really appreciate Jonas Rask, don't forget he's a Fuji X-Photographer. One of Fuji's requirements for that is that you exclusively shoot with Fuji. That's a bit limiting should you wish to test lenses.
I value the views of Gordon Laing (Cameralabs) and Dustin Abbott as well as the very scientific approach of fototest.de (in German) and Lens Rentals' break-down of lenses.
In my experience Fuji has indeed a bit more sample variation than some other brands (I compare with Nikon and Leica) but that is IME more in mechanical issues (loose aperture rings, noisy AF motors...) than in optical issues like element alignments or faults. Anyway, that should not withhold us from evaluating lenses as also 'bad copies' can get into a users hands and he/she might never know it by lack of being able to compare. That is why e.g. fototest.de tests multiple copies of a lens. 

I use Lightroom (Subscription) all the time without any issue.  I find RAF or Xtrans Sensor files are initially sharper then Bayer sensor files from other cameras causing the issues generally identified as "worms".  Lightroom adds sharpening (40) to all imported files, so higher ISO RAF files may tend to show very high noise.  I created a preset to import with, that reduces sharpening to "0" and adds Luminance (50) (same as Capture One does).  With this preset working with RAF files in Lightroom works every bit as well as Capture One with equal quality results.
With these changes, it then comes down to personal preference.  Both are outstanding software and do an excellent job.  For me I prefer the sliders of Lightroom over the Levels and Tone Curves of Capture One, so I stay with Lightroom.  I own both (subscription) and like to play with each at different times, but as for final results I find both the be pretty close to equal, although at HUGH magnification a pixel peeper may disagree - depending on which software he prefers.
As far as import issues with Capture One I can only think you have an older version.  Capture One works closely with Fuji and should accept any Fuji RAF file you have unless it has not been updated properly.  This is the difference between purchase and subscription.  A lot of people don't like subscription, but then cuss when they can't open files from a newer camera without re-purchasing a newer version.  The newest version of Capture One should handle your RAF files.  Pro 12 should handle most except from any of the newest cameras (XS-10, XT-4, ? are questionable) - you'd need to check on their website for compatibility. 

Hello Bruce, I know the database in Pentax forum, it's quite good.
The only advice is take every lens review with a pinch of salt, since no two lenses of the same type are the same.

Hi Bruce. There aren't such a db with reviews on this forum, just some personal opinions, but very often quite valuable, so you may try search through the topicks. Hoever there are some great sites of professional fuji gear reviewers, so here you are a couple for a start:
