Voigtlander Vitomatic II. Small enough to put in my pocket, attractive to look at, fits in one hand.
Second favourite: Zeiss Ikon Contessa LKE for the same reasons but I like Voigtlanders that bit more.
That was the first serious [sirius] camera that I had. I lost track of it, and recently bought a replacement.
Warning!! Handling a Hasselblad can be harmful to your financial well being!
Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
Back to reality - I have been playing with a Rollei 35B with Triotar, but have bounced back to the superb Voigtlander Vitessa for snapshots - For "real" 35mm work I am now well over the Leica myth and have returned to my faithful and reliable Nikon Fs, lots of yummy Nikon Fs with lots of lenses
This is my favorite. I think Yashica made a huge mistake with that partnership with Contax, forever (and unjustly) relegating their proud old brand to a perceived second-tier status, after many years of industry-leading technological innovation in camera electronics. And those old Yashinon DX lenses are killer.
I like my Pentax LX a lot but recently got an MX and secretly, when the LX can't hear and get jealous, I think I may at least sometimes enjoy shooting with the MX more. It's slightly smaller and lighter, noticeably quieter, and works at all speeds without batteries. About the only thing I wish was different on it would be speeds that go to 3200 or, better yet, 6400 as I occasionally use those film speeds with TMZ. OTOH, with an all manual camera it's very quick to meter at 1600 then give one or two stops less, so not the problem it would be with an automatic camera at all.
