I have had this one for a few years now and finally found some 110 cartridge film thanks to the Film Photography Project. I remember when these went on sale and think that they were and still are the only 110 film cameras with interchangable lenses made. Tiny critter, hardly larger than the 110 cartridge. ...compared with a 35mm spool. They originally came in a fitted box with three lenses (these two 35mm and 50mm equivalent and a medium telephoto) a dedicated flash almost as big as the camera and the strap. More $$ got you a motor drive and I think some other stuff. Like it says on the front, it's automatic exposure with no user input. The BW film Branded 110 Fukkatsu came out a bit too grainy for my liking. I took it easy on the shots as well with what I thought to be not too difficult exposure wise. Box recommends D76/ID 11 so it went in D76, 1:1. Somehow the film (100 iso) got packaged in a cartridge coded for 400 iso requiring a strategically placed gob of hot melt glue. Here's what it did. Pentax always had good viewfinders. I wear glasses and aiming this tiny camera was easier than one would think. 24mm lens (standard equivalent) at closest focus distance of 1.2 ft. low light shot, a green light in the viewfinder shows orange as a warning to expect a slow shutter speed. Always wondered why AP put the what must have been considerable effort and money designing this camera with all the unique accessories. anyone serious enough to want to shoot a SLR had dozens to choose from, most with auto and manual features as well. Always forget to delete shots that I decide not to post. They magically appear as thumbs. This weird storefront deserves a return with a different camera and better light.
