![]() So, overall, and especially for the money, I really like this lens. Do I wish there was absolutely no vignetting or distortion at 18mm? Sure, but these issues are not really noticeable in 90% of my shooting. I paid about 1/3 of the price of the Nikon 17-55mm, and I also have a smaller, more convenient lens. It's sharp, has reasonably good AF, isn't too noisy, and has a wonderful constant aperture that can't be found on 1st party lenses for less than $1000. In re-reading my review, I think I come off a bit too negative. I've shot fairly demanding shots in this regard and never seen any fringing. As for chromatic aberations, I was very pleased that this was not an issue at all. Again, PTLens can help with this when it is a problem. Vignetting is also present when at 18mm at f/2.8, but overall, I haven't found it to be noticeable in normal shooting conditions either. As for distortion, there is a bit if you're shooting straight lines along the bottom of the photo, but I use PTLens to solve this quite well. In the bottom-right corner of my lens, it gets a bit blurry, but in real life shooting, I never notice. Even at wide open f2.8, I find the lens is quite sharp. In terms of sharpness, I'm happy with the lens. Also, I didn't feel like my lens hunted more than his did in low light. ![]() (He's a pro wedding shooter.) When I got this lens, I was pretty thrilled to find AF speed close to his lenses. A weekend before buying this lens, I played with my friend's Canon L lenses. Overall, though, the AF is fast and doesn't hunt too often. When doing that, it takes the lens a bit to go from one end of focus to the other. It's quick enough unless focusing from macro distances to long distance. The AF is not a silent, HSM motor, but for normal focusing the noise is not distracting. I wanted f.2.8 for the extra low-light shooting ability and the added depth of field flexibility, and I wanted it without paying $1200 and carrying a lens that weighs in at 3 or 4 lbs. Even Nikon's and Canon's midrange zooms usually have f/3.5-4.5. Essentially, the constant f/2.8 aperture is what did it for me. I purchased the Sigma 18-50mm f/2.8 EX DC to go with my Nikon D50. The money you save can be put towards a 50mm f/1.8. (Comes in multiple mounts Canon, Pentax, Sony, Nikon). It's a fast sharp lens, plus has good Macro capabilities as well.Īnyone with a dSLR, still using just a kit lens, should get this one to replace it, hands down. It gives you a fast lens (f/2.8) at a price under $1,000. If you're looking for a replacement for a kit lens, this is it. I have since used it in the two primary fields I shoot in, events, and architecture. I walked right over to the Henry's table and bought one. I slapped on the lens and took it over to where a model was standing to give it a shot. Using my Nikon D70s I started trying out lens, and a sales rep came over to me and suggested I try this latest offering that they had. I was wandering around the show and happened to stop by the Sigma demonstration booth, a couple friends had purchased Sigma products before and both seemed happy about it. I promised myself I wouldn't buy anything big at the Camera show, man did I break that one.
