The Sigma 180mm F2.8 EX DG OS HSM Macro lens is the biggest, longest macro lens in the Sigma lens catalog. This telephoto lens offers true life-sized reproduction with a 1:1 maximum magnification ratio. Incredible sharpness—thanks to its state of the art optical design—Optical Stabilizer, and a three-zone focus limiter make this a serious lens for advanced macro photographers.
The Sigma 30mm F1.4 DC HSM | Art lens replaces the very popular 30mm EX DC HSM lens as the fast, standard prime designed exclusively for DLSRs with APS-C sensors including the Sigma SD1 Merrill, the Canon EOS Rebel, 60D and 7D and a number of Nikon models including the D7100, D90, and D5100. And based on the updates and upgrades, the 30mm F1.4 Art lens is going to make a lot of photographers very happy.
