No, this is not a typo, nor mine nor did Sigma drop a digit… The extraordinary 18-35 APS-C zoom with constant F/1.8 aperture is going to sale for only $799! Some first previews reported stellar performance, and since this is the world’s first F/1.8 zoom lens we all expected it to cost upward from $1500, but Sigma has its own ideas. I still wouldn’t call this a game changer… full frame is still full frame and no crop sensor can actually match its performance, but this lens might be a very strong reason for many photographers to stay on APS-C cameras. Considering the quality and features of the Nikon D7100 (my review of D7100 is coming within days), and the fact Canon will probably soon announce 70D and 7D MkII, this lens will give you a really good image quality for a small price.
