And Pentax MX and LX. And Minolta XK. And Olympus OM. I suppose Contax RTS, also. I think that's all.
Nikon made a 750 exposure back, too. It takes a full 100 foot roll.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
