I have to amend my original post. Since then I’ve added a Minox to the collection, and it is substantially smaller.
With that said, the Minolta 16 is a fun shoot. Small wheels on the end of the case adjust exposure and shutter speed. They are easily jiggled and must be checked before each shot. Closing and opening the case advances the film to the next frame, but there is no stop. If you close the camera again without exposing it, you lose the frame.
I carried it in my pocket to a horse show at the Big E and on a field trip to Providence.
