Macro lens suitable for 150mm f/2.8 EX DG HSM APO
The Sigma 150mm f/2.8 EX DG HSM macro lens provides excellent image quality at a very reasonable price in relatively long focal lengths. On macro lenses, even on the fastest focusing speed lens, it takes some time to focus from near infinity or reverse. The focal length range of Sigma 150 is limited to between 15 inches and 20 inches (. 38m and. 52m), 20 inches (. 52m), and infinity - or it can allow for a full range.
Full frame telephoto lens suitable for 50-500mm f/4.5-6.3 DG OS HSM
This lens has a 10x focal length range (500mm/50mm=10x), starting from 50mm, which can meet a wide range of needs. The 500mm name at the top of the focal length range is particularly eye-catching. Like most telephoto lenses, the Sigma 50-500 OS has a variable maximum aperture. As longer zoom settings are selected, the maximum aperture opening decreases relative to the length of the lens.
