Favorite one? Like most here who still have and or still use slr's, I have more than one. My first was a Yashica TL Super. Talk about tanks. I always thought of it as the poor man's Nikon. Stop down aperture metering that was always accurate.
I then got a Fujica ST901. Wanted to move up to the latest auto-exposure camera! What a beauty. Compact, and with its sbc blue cell metering, would accurately measure exposure of a black cat in a coal bin (rated to EV -3, but acutally better). Btw, the lenses on the Yashica and the Fuji's never got the public acceptance they deserved. Especially the Fuji's. Their Electron Beam Coating (the SBC on the lenses) made flare almost impossible to acquire even it you wanted it. And they were sharp.
More recently (about 3 years ago) I purchased a Fujica ST801 off eb*y along with two of the old (and real) Vivitar Series 1 lenses. (If you ever get a chance to buy a 35-85 varifocal at a reasonable price, do so, you will love it). I don't think I ever used the 801 as I let my daughter use it to try and get her off P&S's. Unfortunately as well as fortunately, it worked. I can't pry if out of her hands, and don't really want to.
After my Contax 139 went on the fritz, I could only use the f/1.4 Zeiss lens on a Yashica FX3 until I discovered that the FX 103 was a cheaper 139. I now have three as well as three less expensive (but surprisingly good) zooms from 18 to 150. Wonderfully small kit for a 35mm take anywhere.
I also have one of the old Pentax SP' pictured above by I forget who. Wonderfully classic, and fun especially with the accessory prism mounted light meter. That will get you some comments!
Now of course, if I want to take some seriously large negatives, it is still my Mamiya Super Press 23 with a normal and two wide lenses. I just never lusted so much for a telephoto with it like I do with my SLR's. Strange perhaps, because it has viewfinder frame lines for the two telephotos available for it. Still struggling to fall in love with my Olympus SP. I like it ok, just not one I reach for first.
Now you know more than you could ever possibly want to about my photo likes and dislikes. 😀
