I have never tried Lightroom, so I downloaded LR 5.3 trial and installed it today.
Right away it violated my two major requirements.
1.No forced cataloging.
2. No "modern" (unreadable) UI.
And then it violated the ninth commandment, thou shalt not bear false witness. Just like all other Adobe products that are supposed to support my camera, it doesn't really, although the Quick Develop mode seems to, the Develop mode doesn't support any lens distortion correction. It only has profile data for the Fuji X100. I don't have any RAF files from another Fuji at hand right now, so I don't know if LR is interpreting mine as a X100 or whether it interprets all Fujis as the X100. Adobe is supposed to support all Fuji since ACR 6.4 with additions as necessary. I know that mine (F600EXR) is shown in the list that far back. The odd thing is that Quick Develop removes the lens distortion. QD only offers white balance, exposure and a couple others. ACDSee Pro 3 View mode also removes the lens distortion but its Develop mode won't open the image, and you can't save from View. Fuji's own software does the lens but will only save in aRGB.
I see no point in buying it unless it has develop capabilities far better than ACR 6.7. I have seen claims to that effect but don't know what they are right now.
Its catalog view is UNLABELLED. You only see the image filename when you rollover. The Import view shows labels. They couldn't afford ten lines of code for ***** sake? That is really awkward and the rollover is unreliable to boot.
