Hi - I have owned several Rollei cameras in the past including the FX. I now have the Fuji GF670. I would say that in bright conditions the Rollei focusing screen is easy to use, but as the light dims is increasingly more difficult to focus. The Fuji has a beautiful bright viewfinder/rangefinder and will be more useable in low light. The Fuji is well made and not difficult to hold once you get used to it. You can not support the camera by its bellows, but will rest the front metal cover on your hand. You can then focus with your left thumb. Here is a quick cell phone snap of what I mean.2013-10-30 10.07.06.jpg. The Fuji lens is outstanding, as are the Rollei lenses! Regards ---john
