Generally agree with your list (I'll add a Schacht Travenar 90mm 2.8 which is nearly identical to the excellent Rollei-Zeiss 85mm), but I've never heard of a Zeiss Jena 24mm!??!

There was an ISCO 24mm, a Zeiss Jena 25mm 4.0 (also very good) and a Carl Zeiss 25mm 2.8 (C/Y and Rollei - variable in quality).
Any more info?
