I'm partial to the Zeiss Ikon cameras, so my favorites are the Super Nettel, folding Contina II, folding Contessa and nonfolding Contessa, plus the medium format Super Ikonta C and Mess Ikonta B and C.
Yup. I have one. And it's a Zeiss Ikon Contina III with the Novicar Anistigmat f/3.5 45mm. And I honestly wouldn't trade it for a Leica. I might buy anoter and trade THAT one for the Leica. But I love my little buddy.
I really like my Yashica Electro 35 and my Retina IIa. I also like the Canonets, but I don't own one. I wish the door on the Retina was hinged on the opposite side, however. That one problem makes it far more uncomfortable than my Leica IIIs, and if not for that, I would use it much more often than the Leica. Still works great...I just find it slower and more uncomfortable than the Barnack camera. For free (plus $40 service), I can't complain, however.
Another vote for the Canonet QL17 GIII. If I recall that camera has more internal parts than any other camera manufacatured. I liked the size, weight, control layout . . . and the pictures weren't all that shabby.
Voigtländer Vitessa-L with the 50/2 Ultron, which was my favorite 50mm lens for 35mm. It was a great camera, but I sold it eventually to concentrate more on medium and large format work.
I have a nice Voightlander Vitomatic II with a 50mm lens. It's great fun. Just used it extensively on a trip. In MF I have Fuji rangefinders, which are terrific.
It is sometimes a bit cumbersome to use - ASA dial moves much too easily by itself in your pocket/pack - and shutter priority is not my preferred method of metering. But the lens 40mm/1.7 is absolutely one of the finest and sharpest.
