Stick with the 16mm cameras, ha ha
Obviously, there is no perfect sub-miniature camera.
When I decided to try this format, based on information from the Internet, I decided to buy Minolta 16, second version. Awesome, all metal and solid, fully mechanical and with a cartridge designed for manual refilling. A surprisingly bright lens and a large range of speeds. And it can also use any 16mm film stock, regardless of perforation and light sensitivity. It sounds wonderful. I have four of these cameras. But... only one thing spoils the idyll - the fixed focus at 9ft. Why?!! And more annoyingly - in the first version the fixed focus is at 15ft. Why isn't it like 30ft? Yes, there is a MYSTIC filter #0 - so mystical that it was apparently even 50-60 years ago. I like these cameras, as I mentioned - I have four of them, but... 9ft?
I also took the more modern Minolta 16 MG-S - with a promisingly large frame. I haven't tested it yet, maybe I'll have to do some maintenance on it. The situation with focus is the same.
I decided to try a non-fixed focus camera - after some searching, my choice was the Mamiya 16 Automatic. It looks very interesting, but I haven't tried it yet, maybe this weekend. A problem with Mamiya seems to be the cartridges. It just... doesn't.
So I decided to try the 110 format as well. True, the 110 cartridges are not intended for reuse, there is a relatively large abundance of them. There seem to be quite a few cameras with focus control, and the frame is nicely large. Of course, over-automation and simplification lead to quite a few limitations…
All the information you need is over at the
SUBCLUB. It covers the differences between 110 cassettes, how to reload them, how to determine if your 110 camera can use reloaded film -- and what types. It's WAY too lengthy to discuss here, but I'm sure some will try. With some 110 cameras, to use reloaded cassettes, you need to modify the cassette, the camera, or BOTH.
Keep in mind that there are different versions of the Pentax SLR 110. The SUBCLUB covers the differences too.

Thanks for the resources. I scrambled for information, it began to dawn on me. It all seems to come down to the manufacturer's interpretation and the latitude of the film.
I knew there were two versions of the Pentax 110, but since I couldn't find the second version in the listings, I hadn't noticed the differences. And the important thing is the compensation button. Ok I found one, it's already ordered.
