Chinon CEII Memotron (1977)
Even a revered Alpa of Swizerland "loaned" Chinon CEII Memotron design with minor external modifications to their Alpa SI 2000 the first of the Japanese-made Alpa cameras.
CEII has an electronically controlled metal focal plane shutter. Stepless automatic-speeds from 2 to 1/2000 sec. plus B (1/90 sec flash sync.) Manual mode has 12 mechanical speeds, (1/1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000 and 1/2000sec.
Exposure control by an automatic aperture preferred exposure system... simply set aperture by turning f-stop ring and the camera sets the shutter speed automatically.
Depressing the shutter release button halfway activates meter. Memory exposure control switch lets you take a meter reading for a subject and lock it in so, that exstreme contrast or strong back light will not misguide exposure system.
There is no leatherette on the sides of the prism housing. The pieces are waiting until I get a proper glue / tape to fix it. Using glue is OK in this case, because there is no screws etc. on this area. Unfortunately Chinon uses rather thick and tough vinyl, which seems to be hard to fix. A proper tape would be Industrial Specialty Adhesive (3M) and a good glue for this purpose is Pliobond. Because of the flat surfaces most of the one component contact glues will do.
