A Sigma 10-20mm F4-5.6 for €270?
I've an opportunity to buy a Sigma 10-20mm F4-5.6 (Nikon mount) for €270 shipped. The only catch would appear to be a very tiny scratch on the edge of the front element (I've circled that in yellow)
From what i've heard from the seller and elsewhere online, it shouldn't have any effect whatsoever but I just want another opinion. Also, is €270 a reasonably good price? I alternate from thinking it's a bargain to not.
