Most compact version of the 135/4 Tele-Elmar?

[quarth]

All -

For anyone that has an old 135/4 Tele-Elmar... my understanding is that there were 3 versions produced, all with essentially the same optical formula, and just variations to whether the lens head and hood is detachable, etc. Seeing that I plan to travel extensively with this, can someone recommend (if applicable) the most compact of the 3 versions?

Also... does anyone have the (even imprecise) dimensions and/or weight of the lens? I've seen pictures, but am having a hard time understanding how big/heavy of a lens I'm looking at, since all the pictures have nothing to reference outside of the lens.

Thanks!
