Yeah, I tend to agree that Lightroom, which is built on Adobe Camera Raw which has been around for many a year, needs its basic code brought up to date. However, that would cost money and since it seems to have been optimised for Canon/Nikon files and works pretty well for those files, I don't see them doing it anytime soon.
I'm starting a search for something to replace Lr. OnOne will have a new raw processor in the fall and Corel has just released a new version of After Shot Pro which may be worth a trial download.
The trouble is I'm used to Lr, I know it and it does certain things very well, like the print module and soft proofing, adjustment brushes, etc. Photography is a hobby for me and I want things to be fun and easy. Learning a new program, well...it may not be so easy.
