Sigma’s full-frame 50-500mm f4.5-6.3 stabilized telephoto zoom is a promising looking model for wildlife, nature and sports. At $1,660 it’s temptingly priced for a lens of this potential, but how well does the Canon mount version perform? Read on to find out.
Sigma is the largest independent lens maker in the world and produces a number of specialist lenses outside of those normally found in the ranges offered by the camera marques. This lens is one of those models.
As a full-frame lens it’s a tempting addition for anyone looking to capture elusive nature and wildlife and may even be a useful addition for sports and action. This lens is particularly attractive, however, when used on an APS-C body, where it has the equivalent field of view of a stabilized 75-750 mm.
As usual with Sigma, it has a highly promising specification. In addition to an ultrasonic type AF motor for fast near silent focusing and built-in four-stop stabilizer, it has no less than four SLD (low dispersion) glass elements, a rounded diaphragm consisting of 9-blades and focuses down to 0.5m at 200 mm. Although the filter thread is a sizeable 95 mm, it measures 218 mm in length (un-extended) and weighs in at 1.96 kg (4.33 lb).
