The Lomography Fisheye One is a very fun simple camera with an incredibly wide 10mm lens. It requires a single AA battery (not included) for the flash but is otherwise fully mechanical. This example is the turquoise colored version.
Condition notes The camera was tested with batteries and film installed and all functions are working correctly (the film was not developed however). The camera has considerable cosmetic wear (see photos) but this doesn't affect its functionality.
