Not quite a spy camera, but the Lomography Fisheye Baby 110 and the Fisheye Baby 110 Metal will fit into your pocket effortlessly. After all, these are the smallest Lomos ever.
Both are fully working miniature version of the Fisheye 2, which was especially designed to fit 110 film, producing the same sized 170° fisheye pictures as big brother and hides easily in every pocket. It also comes with a bulb mode and is able to capture multiple exposures – just load it with 110 film and you’re away.
The Baby 110 is the basic model, while the Fisheye Baby 110 Metal comes with an additional PC flash adaptor and is wrapped in shiny metal to make it even more eye-catching.
