I used one of these from 1975 to 1998 with excellent results in all conditions. Metering with non-Mamiya lens was very easy by just pushing the rewind lever forward and adjusting the apeture after selecting the shutter speed. As others have said, the 42mm screw mount alows the use of a wide variety of lens' from many manufacturers. It's not a bad basic 35mm camera although it's limited by the1/1000 top shutter speed.
