Are there any huge problems with this lens that would dissuade you from getting it? I want to replace my 28-105 3.5-4.5 II with a fixed aperture, fast zoom, and I browsed through the archive for the Sigma 24-70 2.8 and I must say, I LIKE what I see.
On top of that, it's SO CHEAP in Hong Kong, where I'll be this Christmas. It retails for like, $370 new. Way cheaper than the L equivalent, and even cheaper than the Tamron 28-75 2.8, which I don't want because I'd rather have the 4mm on the wide end, and I also love SIgma's build quality.
How bad are the flare issues etc...? Or should I go for it? I realise it's not USM but it just seems like such a great deal. This just looks like one hell of a lens for a hell of a price!
