Pentax Auto 110

The Pentax Auto 110 is a tiny beauty that is a joy to shoot with. It is a perfect SLR in a tiny package. The viewfinder is bright and the camera is dead simple to use. That being said, I am not horribly impressed with the results.

Already enamored with the ME Super, this Auto 110 was too good of a deal to pass up even though it’s a little harder to find 110 film cartridges. It came with both the standard lens and the Asahi Pentax-110 f2.8 70mm.

Example shots

Here are some examples despite a developing comedy of errors. I modified a design found online and 3D-printed a developing reel in three parts then assembled it.

The result looked good but will require modification to get 110/16mm film to load.


Next, I cut down a plastic bottle to fit into my AnscoMatic developing tank and prepared two pieces of electrical tape. What I failed to do was learn how to open 110 film cartridges. One broken film, a razor blade, a pair of pliers, and several bandages later the film was in the tank.

Approximately 2/3 of exposures developed (ish):
