The Chinon CM-4s is a simple but good quality 35mm SLR from the early 1980s which is compatible with popular K-mount lenses (most commonly used on Pentax cameras such as the K-1000). The included lens is a sharp Auto Chinon 50mm f1.9, a highly regarded 'nifty fifty'. 

Overall, we would say this is a worthy alternative to the K-1000 and quite similar in functionality. Its Copal Square-style vertically-travelling shutter is a bit noisier than the Pentax's cloth shutter but it seems to maintain speed accuracy for longer periods. Our only (minor) gripe with the CM-4s is that its flash sync speed is only 1/60, which is slower than typical for vertical shutter designs (but equal to the K-1000). This is mainly only a nuisance if you like to use fill flash on sunny days with wide apertures.

The camera requires two LR44 or SR44/357 batteries (available as an option). 

Condition notes
The camera was tested with a battery and film installed (the film was not developed however) and all functions are working correctly. We verified the camera's shutter speeds and light meter are working with very good accuracy. The camera and lens are in very good cosmetic condition (see photos). The included 'ever-ready' case is good condition with some wear.
