At first glance, the Sigma 45mm f/2.8 DG DN seems to be a run-of-the-mill, reasonably fast normal lens designed to cover the full frame format. In fact, its 45mm focal length is closer to normal than the classic 50mm, as determined by the diagonal of 24 x 36mm frame, which measures 43.26mm.

Admit it. You’ve always wanted a 70-200mm f/2.8 zoom lens. For many professional and enthusiastic amateur photographers, it’s the backbone of their lens arsenal. Here’s a great candidate if you’re ready to take the plunge.

The long and the short of it, Sigma America just announced two new full-frame prime lenses designed specifically for full-frame mirrorless camera systems. Joining the Sigma lens lineup are the world’s first f/1.4 diagonal fisheye and a rugged, lightweight Ultra-Tele.

The Sigma APO 150-50mm lens is a moderately fast, super-telephoto zoom designed to work with both APS-C and full-frame DSLR cameras. It offers quite useful close focusing (7.2 ft) and two modes of what they deem "optical stabilization" (OS.)
