Sigma QC 18-35 or other
« on: December 21, 2013, 09:35:47 PM »
I've only bought one sigma before, a 50mm.  Just picked up the 18-35 F1.8 and had this for de-centering.

Wondering if anyone else have had copy variation issues.  The difficulty I had explaining de-centering and the issue to the camera store people upon returning, didn't make me eager to try another one from them that might also end up needing returned.  They'd never heard of decentered before, at two of the stores...actual camera stores.  "You mean it isn't focusing right?"  It was pretty sad.  I even took the full size images down and am not even sure they got it then.  That above I think was F2.8, it was at 18mm.  One framed in upper left corner then just reframed same area to the right side, which was horrible.  So this has me wondering if it's common or not common with this one.

I have had plenty of decentering issues with Canon lenses... It is a pain and I exchange/return them right away. Canon has a very hard time correcting it.

Try another! Chances are the second time around it will be OK  ;D I have yet to get two decentered lenses in a row *knock on wood*... Although I wish I did not get one in the first place!
