My last real dilema is the 135. Keh sent me a tele-elmar with perfect glass and a multiated flange Made some shots with it, but OMG is it a pig. 505 grams--that\'s OK for a superspeed lens, but an f/4 it\'s past the pale. This was the early version at a good price. Obviously I have to return it.
I fear I may need to bite the bullet on the APO, which is still a wallmart shopper at 450 grams. My Canon Black LTM is 400, and not bad but not deadly.
I wish CV had gone all the way.......
If I was smart, I would return the summarit-m 90, keep the lanthar, and put the money into the telyt.
