Great lens, especially for the money,
Verified Purchase(What's this?)
This review is from: Sigma 28mm f/1.8 EX DG Aspherical Macro Large Aperture Wide Angle Lens for Canon SLR Cameras (Electronics)
I have been a fairly serious hobbyist photographer for about a year now, since purchasing my Canon DSLR. Many hours spent researching photography in general and lenses in particular have led me to this lens. From what I've found online and on Flickr, it doesn't seem to be very well-known, especially compared to this other Sigma lens, which I also considered:Sigma 30mm f/1.4 EX DC HSM Lens for Canon Digital SLR Cameras. In other words, this purchase felt more risky to me, but I think it turned out quite well.
-Future-Proof: If you're considering this lens, you most likely have a "cropped" sensor DSLR. All but the most expensive DSLRs have them. Many new lenses - "DC" lenses for Sigma, "EF-S" lenses for Canon - will ONLY fit on cropped-frame cameras. In the future, if and when full-frame cameras become cheaper and more popular, these lenses might not fit new cameras. This "DG" lens, however, will fit on both cropped- and full-frame cameras (albeit with different focal length equivalents - it takes wider shots on full-frame).
-Depth-of-Field: I'm loving the small DOF on this lens. It's nice and smooth.
-Low-Light Photography: With its large aperture, it's fast in low light. Quite fun if you're used to slow zoom lenses!
-Construction: Looks nice, feels nice, and the focus ring has just the right amount of resistance.
-Auto-Focus: The AF could be faster, but that is to be expected without a hypersonic/ultrasonic motor. It also sounds more gravelly than I'm used to, which is a little unnerving, but it seems fine. I have not seen any AF accuracy problems.
-Size/Weight: It's hefty, but it's nothing compared to some of those telephotos out there. Admittedly, that's an apples-and-oranges comparison, but still. I love the size and weight; your mileage may vary.
-77mm filter thread size: Again, it's big. Filters can be expensive. On the other hand, it looks and operates like serious business.
-Image Quality: I am very pleased with the quality, but I'm no studio photographer. I don't take pictures of test charts for fun.
