I can only speak for myself, but the 135L is the last of my Canon lenses I'd give up. I think it is really unique among Canon lenses - one of the few that has a specific signature style. That goes for FF anyway. On crop cameras, well, not so much. It's OK on my 7D but far better om my 5DII. It is on FF that it hits the sweet spot of focal length and DOF.
i just purchased one today, because my 85mm was my most used lens on crop, and i've moved to full-frame.
anyone have a similar experience? if so, how did it pan out for you?
Yes. 85mm is a favorite of mine on crop, don't like it on FF. Don't like 50mm on crop, like it on FF. Not crazy about 135mm on crop, love it on FF.
