Wow, I didn't realize that I would become a point of inspiration here!
I have 3 digital cameras : a Pentax Q7, an Olympus M10, and a Pentax K-3. That makes up my small, medium, and large systems.
Like most photography enthusiasts, I have many more film cameras than digital cameras!
For 120 film I use a Bronica ETRS. I recently shot a roll of Velvia 100 through the Bronica and depending on how it comes out I will make that camera my dedicated reversal film setup. Medium and large format transparencies are
awesome and melt my heart. The ETRS is not loaded with anything right now.
For 135 film I primarily use a Pentax PZ-20. It has an Av shooting mode which allows me to use DA and FA lenses on "A". The PZ-20 has a roll of Agfa Precisa in it.
I received my father's ME Super and my uncle's Zenit TTL but these are rarely used. They are nostalgic but fully functional.
There's a perfectly working ZX-60 kicking around that sits unused since I got the PZ-20. I also have a Yashica TL Electro X that my wife gave me as a birthday present. It's a super fun camera to use due to the great ergonomics.
Lastly, I have a collection of Spotmatic bodies, two of which have CLA'ed by Eric. My favorite Spotmatic to use is an ES II followed by the F model. I'm thinking of slimming down my collection of Spotmatics and only keep the ES II and F. I have a roll of Kodak BW400 in the ES II right now.
One "problem" with film bodies is that they are relatively cheap. It's pretty easy to find them for $5 to $50 in "good enough" condition. I'd be spending more money going to the movie theater compared to buying a film body!
