I'm very much a wideangle person, next lens for my Leica M6 will be a 35mm (although I think it will Voightlander rather than Leica).
First a correction
The Contax cameras I mentioned were actually the Rollei QZT/QZ35W35.
I tend to be a "short tele" person and have a lot of 85mm - 100mm lenses. In my Leica outfit I have the 35 Cron v IV and when I got the M8 I added the 28 Elmarit Asph. Wider that those I reach for an SLR/DSLR so that I can see the distortion as it happens. For me wide means getting close, rather that capturing the entire world
The short tele equates to the way that I narrow my attention when I see something interesting. Normal focal lengths seem to preserve my usual usual perspective. These comments are about FOV rather than visual DOF renditions.
The CV 35s have gotten some good reports, so go for it.
