1. Sigma makes a good lens but this one seems to be a medium quality the focal point is very unforgiving you'll ether have a bright back ground or dark back ground as you try to adjust the ISO, AP, SP to compensate the lack of depth.

1. I purchased the 105mm F2.8 EX DG Macro to compliment my "standard" 18-50mm F2.8 zoom for my Sigma SD14. The lens is tack-sharp from f5.6-7.1 up to f11 plus... Produces bright, clean images and the large aperture gives superbright finder views (great for my elder eyes). Compact size, love the focus limit feature; like all EX Sigmas, the lens is well constructed and beautifully finished. Focuses quickly, even on the marginally slow SD14 body. Super deal here on Amazon. With crop factor, focal length == 179mm on SD14. Would recommend to all, regardless of camera body decision. 5 stars!
