Why not? The image quality should be excellent, and I know two German Stock photographers, who work with the Fuji-System. If you work with models, it is possibly tricky. Models think a professional must have a big camera. But in the future professionals might have the small, elegant Cams and amateur photographers will take pictures with the old-fashioned SLRs. Who knows? My problem with modern system cameras as Fuji, Olympos etc. is that these cams are too small for my hands and otherwise I can use Nikon blind, even in darkness.

double posting, sorry

And, I'm sure, I will not work with models 

Good luck, I'm sure, you will be able to make high quality pics with your new Fuji-Cam!

Sure, I will make!
