We weren't able to locate the manual for this camera but its main features are very simple and intuitive. The most unusual feature is that there is only one zoom button (for zooming in and out). In practice we found it to be quite quick and simple to use.
Condition notes We tested this camera with a battery and film installed (we did not process the film). All functions are working correctly. In addition, we verified the film plane focus accuracy with an autocollimator. The camera is in good cosmetic condition with some minor wear from use (see photos).
