My personal opinion about Sigma lenses is that I've tried them
on four separate occasions and on all four occasions ended up
returning them, buying the manufacturers' lens instead.
Sometimes after multiple exchanges. For straightforward defects
or poor performance optically: their build quality is poor and
variability between samples is high. So I don't buy or use Sigma
lenses anymore.
My local dealer's opinion is that he gets an inordinate number
of returns on Sigma lenses so he has discontinued carrying them.
YMMV.
