Time to poison you more, since your Ikon uses the M mount.

Aside from 50mm, 35mm is the classic rangefinder focal length, and the aperture provides more than enough flexibility and the focal length is perfect for taking pictures of people.

As for me, i'm considering this

ZF is a Zeiss Designation lah.

Leica uses the designation of M/R/ER or the -vid, -lux, -cron suffixes.

Added on November 11, 2009, 6:58 pmBelieve it or not it's actually easier due to the shorter flange distance, the need for a longer exit pupil is no longer there. It's just that RF users have generally gravitated towards portrait and street photography, so there's really no market for these beasts.

The TeleSuperAchromat if adapted to 35mm size does have a near F/1 aperture. Plus if Leica can make the 0.95 F Noctilux, it doesn't seem that far fetched.
