Awhile back I replaced a Tokina 12-24mm f/4 ATX-Pro DX due to lack of use and financial reasons. I picked up a new-in-box Sigma 15-30mm f/3.5-4.5 EX DG for $200 on eBay not expecting much, just wanting to have something wider than 28mm of my normal zoom. My lowered expectations have turned in to me being VERY impressed with this lens! Its build quality is VERY impressive, matching the Tokina (except for the lens cap) though the Sigma EX rubberized coating may not hold up as well. Sharpness and color-rendition are also spot-on. It has really re-sparked my interest in wide-angle photography. My only gripe is pretty minor, a decent bit of flare w/ the sun or light-source outside but near the edge of photos. Posted below are some pictures taken of my new home and around the neighborhood (with a few from my Sigma 70-200mm f/2.8 EX D and of Epcot, my crazy puppy). These are my first image posts here (I'm prone to becoming more interested in the gear than the images). 15mm, f/13, 1/500 sec. 15mm, f/3.5. 1/1000 sec. 19mm, f/11, 1/500 sec. 15mm, f/10, 1/400 sec. 15mm, f/9, 1/320 sec. 200mm, f/4.5, 1/1250 sec. 70mm, f/2.8, 1/250 sec. 70mm, f/2.8, 1/250 sec.
