Sigma 100-400mm f/5-6.3 DG OS HSM | C
Super-telephoto lenses tend to weigh heavily on your pocket and your shoulder, but Sigma is at least trying to keep you away from the osteopath with its latest super-tele, which tips the scales at a relatively modest 1.16kg. It’s also fairly compact, measuring just 182.3mm by 86.4mm.
Thankfully the diet doesn’t seem to have compromised optical quality, as the 21-element design incorporates four SLD elements to edge out fringing. Like Sigma’s new 24-70mm, this lens also packs an all-new Optical Stabilizer that boasts a trick gyroscopic sensor that can detect shake in any direction – horizontal, vertical, or diagonal – to effectively counteract shake whether you’re shooting in both landscape or portrait orientation.
Sigma’s electromagnetic diaphragm makes another appearance here, with its nine-bladed rounded construction designed to produce creamy background bokeh. This feature is especially important given the lens can – at a push – be used for macro photography, with a minimum focusing distance of 160cm and a maximum magnification ratio of 1:3.8.
And not content with releasing this lens and its new 24-70mm f/2.8 (see previous page), Sigma has also launched a pair of new primes: there’s the 14mm f/1.8 DG HSM | Art that’s being touted as the world’s first and only f/1.8 ultra-wide lens; and there’s the 135mm f/1.8 DG HSM | Art, which boasts similar specs and adds aweathersealed mount for extra versatility. As with the other lenses in Sigma’s Art range, both promise premium build quality and performance.
It’s around 25% lighter and 10% smaller than Nikon’s 80-400mm f/4.5-5.6 AF-S lens, but hopefully this lightened lens will punch above its weight.
