I just wanted to point out that I got a call from McBain and the dream lens that I have been heavily anticipating all these years is finally coming in. My preorder just went through today! Sharp corner to corner with unreal centers wide freaking open at F1.8, the second review to come out on the Sigma 18-35 F1.8 is going to take my Nikon D90 to new levels. It will finally show all that its little APS-C sensor could be and why the bulk and handling of a DSLR is worth its while over the mirrorless cameras and advanced small sensors out there, including my own Nikon P7700. End of August available in Canada. Can’t wait. And to think I was psyched over the Nikkor 17-55 F2.8 before! P.S. after this lens, its the Nikkor 80-200 F2.8 2 ring version….in several years time haha.
