Asahi Pentax Auto 110 System

I lived through the 70’s and 80’s, but never heard of the Auto-110 system until 2015, when I started looking for interesting lenses to connect to my Fujifilm X-E1. The Auto 110 is one of only a few SLR cameras designed for the 110 cartridge film format. Because the registration distance is very small, and the lenses are only made to cover the film size of 110 (13 mm × 17 mm), the lenses will only work on smaller digital cameras, like the X-E1, or MicroFourThirds cameras.

Here is the first set that I bought, which included the camera, a flash, auto-winder, and 3 lenses 18mm, 24mm and 50mm. Now if you want to use the Auto-110 system with film, you can still purchase new 110 film cartridges from Amazon and eBay.

All lenses for the Auto-110 system are f2.8. There is no aperture in the lenses, since the shutter in the camera is also the aperture, only opening part way, with a square aperture opening. On the far left of the photo above, is the Fotasy PTX110-FX adapter.

The 24mm lens is the smallest lens. In fact, it’s so small that when using it, I’ve found that my fingers get into the image sometimes.  Using these lenses with an APS-C sensor camera, you’ll notice some vignette and fuzzy edges from the lenses, but I think they can add some character to the photo.

I’ve added 2 more lenses to my set. The 70mm and the 20-40mm. Both are decent sized lenses.
