For a coat pocket camera, I probably would opt for one of the small rangefinders from the 1970s. There are some nice cameras from Vivitar, Konica, Canon, Olympus, Minolta and Rollei/Voigtlander. There's also the Zeiss Ikon S 312/Voigtlander VF 101, which are a bit uncommon but are solid rangefinders with a 40mm Tessar/Skopar lens.
I think the Pentax MX with the 40mm pancake lens is the smallest full featured SLR, but it has some weight to it, as a quality camera should have.
-I like for compactness the Leica r4s (not the first r4 with electronic problems), with elmarit 35 2,8 (and special the first version of that lens, the second and third is over corrected and lost they're ''character'', those is good only for sharpener worry'ds..), the combo is small, light and the same time pleasure to use.
Where'd you find that out? I'm always interested in having any misconceptions of mine corrected.

I think out of all the lenses I've owned, there was the most variation of the 28mm f/3.5 from it's beginnings as the massive 58mm front Super Takumar, through the smaller Super Takumar, S-M-C Takumar, SMC, and SMC-M. It was changed fairly significantly with each generation.
I think the K one is the sharpest of them all, and I believe it's generally regarded as the best of that lens by most.
When I need to carry an SLR that is smaller and lighter than my other SLRs, I carry the Pentax ME.
