>>3587468I had Sigma's 24/1.4 for a week before I returned it. It was optically great, but just too fucking heavy for what I was using it for. I just saved and got the 24/1.4 gmaster instead and it's never off my camera. I know that's even MORE expensive, but it's a perfect lens for me.
If you're really low on cash I guess you can't really go wrong with the 28/2 with a price like that, but I still think you might not be happy with it in the long run.
