Sigma 150mm f/2.8 EX APO DG OS HSM Macro - Sigma SA, Canon EF, Nikon F, Sony A Mount

The Sigma 150mm f/2.8 EX APO DG OS HSM Macro is a high-performance telephoto macro lens providing 1:1 magnification. This version introduced Optical Stabilisation (OS), which is highly beneficial for handheld close-up work and general telephoto use. Its focal length allows for a generous working distance, making it ideal for photographing insects or skittish subjects. The f/2.8 aperture also makes it a capable portrait lens with smooth bokeh. SDS pays particular attention to the Optical Stabiliser, ensuring it engages and disengages correctly without unusual noise or "jumping" in the viewfinder. We check the focus limiter switch and the HSM motor for precision, as macro work requires exacting focus. The tripod collar should be present and lock firmly. We also inspect the internal elements for any signs of haze that can occur in older telephoto designs.
