My favourite titanium body 35mm compact camera is Contax T, and Contax T2 I also have a Minox M.D.C, which has a titanium shell, but inside is still plastic. Contax T has a five element Carl Zeiss Sonnar 2.8 /3.8 lens. Contax T has mechanical shutter. One battery lasts for years. Titanium body camera is scratch resistant, I do not need camera case for it. Contax T is probably the smallest full frame compact 35mm titanium camera. Leica similar camera is a bit larger. I have two Contax T, one silver one black. I like the silver version more.
