I get most of my SIGMA's direct so, this one is around S$1,500.00
Yes its front element is protruding quite a bit, just be mindful when using the lens. It's a full frame lens and it also works on A700. I'm cutting down on SIGMA DC type lenses.
Hmm.. this piece will complement my other 15-30mm DG lens very well, same bulging front element.
I was even thinking of SIGMA's 14mm widey - but reviews read so far, wasn't encouraging; flares very easily, and edge softness very extreme.
The 12-24mm flares too, but I think sometimes, flare effects are nice on certain scenes. Otherwise, why would Photoshop include Flare in its Effects menu?
