Yup, I'm old and so are my Pentaxae. (Or Pentaxes if you prefer). I bought my first Pentax in 1965... a black H3v, and I still use it. No problems getting batteries for it either! So, my only bodies are screw mount M42. Used mostly with Tri-X. Yes, I do have a couple of digital cameras but they are not as much fun as shooting film. The attached shot of Sammy Davis, Jr. was shot at Lake Tahoe in 1966. It was an outdoor benefit performance for a charity.
And, shot hand held with the H3v.. 200mm f/3.5 pre-set Takumar on a tightly cropped Tri-x neg.
Maurice in Utah waiting for the fix to clear the negs.
