This Sigma 100-400mm offers a good compromise between budget 70-300mm lenses and whopping super-telephoto zooms. It’s well-built, handles nicely and boasts some useful up-market features.

Small and light for a ‘super-tele’ zoom, Good handling and performance, Reasonably priced

Only the mounting ring is weather-sealed, Fairly narrow f/5-6.3 aperture rating, No tripod mount ring available

I have to say once again Sigma surprised me quite nicely. Despite being a bit slower aperture-wise and, by default, weaker than the new lenses from Canon/Nikon when it comes to apertures and vignetting, it didn’t have any problems to win a resolution duel with them.

High quality casing,, Excellent image quality in the frame centre no matter what focal length you employ,, Very good image quality on the edge of APS-C sensor,, Good image quality on the edge of full frame,, Lack of problems with spherical aberration,, Slight lateral chromatic aberration,,...

Distinct vignetting at longer focal lengths on full frame,, A bit too many flares and losses of contrast during the work against bright light,, Minimum focusing distance the worst in this class of equipment,, Slow autofocus.

The new Sigma 100-400mm F5-6.3 DG OS HSM telephoto zoom lens offers very good image quality throughout its versatile focal range, whilst being light and compact enough to make it suitable for hand-holding.

With all eyes currently on Sigma’s amazing Art and Sports ranges, we almost take its Contemporary line-up for granted – but this fresh release’s massive reach and sharp optics swiftly remind us why Sigma is so successful.

While its f/5-6.3 aperture is a little more restricted than some other 100-400mm, the Sigma 100-400mm f5-6.3 DG OS C is significantly more affordable. It’s also comparatively light for a lens of this focal length range and this adds to its attraction, as it’s easier to hold and use over long periods...

Good price for the focal length range, Lightweight, but nicely built, Superb Stabilisation

Vignetting at f/8, Relatively small maximum aperture, Variable aperture
