The Sigma 50mm f/2.8 EX Macro lens also features the new deluxe EX external finish Amazon.com Sigma launched its first standard 50mm macro lens in 1990, and followed it up with an improved model in 1998. The advent of digital SLR cameras, however, required updated optical technology and a better imaging performance. Enter the latest incarnation of the 50mm macro lens, with an improved design that corrects for various aberrations. Designed exclusively for Canon SLR cameras, this macro lens is specially coated to get the best possible color balance while cutting down on ghosting caused by reflections from the digital image sensor. The lens also includes a floating focusing system, which allows you to precisely photograph objects throughout the entire focusing range. Most importantly, this standard macro lens makes it possible to enjoy better communication with your subject. When viewing through the camera's finder, you'll be able to move the subject and make precise adjustments. For example, the lens offers a close working distance of 7.4 inches, making it extremely convenient to take close-up pictures of a fossil or other inanimate objects. Other details include a minimum aperture of f/45 that provides a greater depth of field than most lenses, a screw-in lens hood that makes it easy to attach circular polarizing filters, and a 46.8-degree angle of view. All Sigma lenses carry a one-year warranty.
