matthew saville: YES, Sigma please give us a 14-24 f/2.8, NOT a 10-20mm f/4! (full-frame)
Although, personally as a lightweight traveler, I'd much rather see a ~16-18mm f/2 that accepts front filters, than a 14-24 2.8 if it's going to weigh anything like the Nikon or Tamron...
Yes, Please Sigma I am begging you, produce a 16mm prime at f2 or 16-24 or something in that range at f2. or 17mm at f1.8 :) (Full frame with filter support of course).
JWest: These pictures really are amazing. But is it just me, or are there a lot of "jaggies" in some of them? It's especially noticeable on the hard lines of the shuttle - almost like the pictures have been aggressively compressed.
It all comes down the browser you are using, some browsers will do bi-linear rescaling, while others will only do N-neighbour down sizing etc. It's not a fault of the camera :)
