Thank you for viewing. Shutter fires at all speeds. There is some clouding in the viewfinder due to age, but the visibility and double image are clear. Red-eye indicator works. There appears to be slight clouding in the lens. The bellows are clean. This is an old camera, so please consider it as junk. Please refrain from any post-purchase support. #Mamiya #Zuiko #Olympus #Zuiko #Contax #CarlZeiss #Hasselblad #Bronica #Topcon
