I think it might be worthwhile for owners of this lens to occasionally check those screws to make sure they're tight. I know I will be doing it with mine.

Agree that inserts would be best and considering what the lens cost. When you get the new part, be carefull not to over-torque. With cracks at multiple sites, that was most likely a contributor here. The cast Al really doesn't like to be overtorqued. Use some Locktite (not the perm. type)

Mine is ok and I have never seen this before.

Oct 25, 2009 09:11 | #23 I'm sorry I'm so dense, but can you show a picture not so close up. I'm not understanding what part broke. Is that part of the monopod or a piece of the original/replacement lens plate that broke?
