I would like to upgrade from my 24-70mm F2.8 IF EX DG which has been a great tool for me.
Makes one wonder about having a lens with no coatings whatsoever on the lens elements. Does this predict a certain amount of flare and coma problems?
Just wondering.
The lens comes with Super Multi-Layer Coating:

“… In addition, SIGMA’s Super Multi-Layer Coating helps further reduce flare and ghosting and provide sharp, high-contrast images even in backlit conditions…”
