Pentax ME super
Kiev 60 (complemented with some Zeiss Jena glass)
I like them because these are very straightforward, no bells and whistles cameras, that truly deliver. Superb viewfinders, robust and, at least when it comes to the first two in my list, great ergonomics (except for the idiosyncratic Leica film loading mechanism, which is nevertheles compensated by many other advantages, like stealth).
35 mm SLR: Canon AE-1P, with a squealing shutter and all the seals mostly gone, and I still love it. I can't wait to see it after a complete CLA tomorrow.
MF: Yashica-Mat 124G (this is probably going to change when my Hasselblad 500 C/M arrives)
My Rolleicord III. I've tried different medium formats, trying to get the next best thing, but until I'm able to drop money on a Rolleiflex, I don't think I'll find anything I enjoy as much.
