how does this lens compare to the Sigma 150 2.8 macro os ?
Asked by: Ron
The IRIX 150mm f/2.8 Macro 1:1 Lens is a weather resistant manual focus Macro lens with sharp glass and a haze coating to create more contrast in the images. The 1.1" minimum focusing distance for the IRIX lens is similar to the 1.25" for the Sigma lens. The Sigma APO Macro 150mm f/2.8 EX DG OS HSM Lens is a auto focus lens with a image stabilization, in a well built, (not as weather resistant as the IRIX), lens body. The Sigma specs say: " The optical design employs three SLD elements to virtually eliminate chromatic aberrations and color fringing for improved clarity and color rendering. A Super Multi-Layer Coating has also been applied for greater contrast when working in strong lighting conditions" Both lenses will work fine for macro photography, the Sigma is autofocus, more durable and offers more edge sharpness. The IRIX focuses closer and cost a bit less.
