Revue was and is the film and photo department of QUELLE. They sold Super8 cameras (also projectors and others) with their own brand name. They had own model types build from Chinon, Cosina and others.
Revue/Quelle was the brandname for people who want to get bargain products. But the quality of some cameras is very good! The cameras are mainly not so high sophisticated, but few top models have also 8 x or 10x zoom, 1,18,24,48 fps, fader, lap dissolve and are very solid in metal housings.
I have Revue as a workhorse for outdoor and adventure.
advantage: No weakness of the metal cameras is known, except the rubber eyecup! If you have problems - put the camera in your icebox and after 5 -10 minutes cut the rest of the eyecap. Maybe you can get replacements parts.Lenses have a good quality (CHINON)
