Digital Camera World Verdict

So-called ‘superzoom’ lenses tend to give you a mighty zoom range at the expense of a degradation in image quality, especially when it comes to sharpness, color fringing and distortions. This Sigma superzoom for APS-C format cameras gives you a bigger zoom range than most, equating to 27-450mm in full-frame terms (28.8-480mm for Canon), while still delivering very respectable image quality, although handling could be better. All in all, it’s a very versatile lens that makes a good travel companion.

The Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM | C definitely serves a purpose. When you’re out and about for some casual shooting, a collection of spare lenses can really weigh you down. Wouldn’t it be great if you could get a single lens that stretched from generous wide-angle coverage to powerful telephoto reach, at just the twist of a zoom ring. That’s the whole idea behind this ‘superzoom’ lens.
