I think I will try the Sigma 35 one more time in a few months... If it still shifts like crazy I will give up!
But I loved the lens... I just want it to work right in all conditions. But next time I will order via Amazon and have free return shipping if anything. Canon did some AF adjustments on my body and replaced some internals so my camera should be ideal again to test it out with!
What internals did they replace?
I'm glad you're planning on being back with us, Invertalon!
