Digital Camera World Verdict

Leave nothing unseen. The Sigma 8-16mm f/4.5-5.6 DC HSM allows you to really capture practically everything around you, with a massive 121-degree viewing angle that really has to be seen to be believed. The best part is that it’s a well-made lens in all other respects, too, with a durable construction (though weather-sealing might have been nice) and great optical quality. If extreme wide-angle is your thing, this is the way to do it – with style and sophistication.

The reduction of every single millimetre in focal length makes a noticeable difference in wide-angle coverage. The Sigma 8-16mm f/4.5-5.6 DC HSM lens shaves 2mm off the shortest zoom length of competing zoom lenses, boosting the viewing angle from around 108 degrees to a monstrous 121 degrees (measured on the diagonal). The difference is obvious and eye-popping as you look through the viewfinder.

While short in focal length, the Sigma isn’t short in build, and is a third longer than Canon’s 10-18mm lens. It’s twice as heavy as well, but the construction feels solid and sturdy. There are no weather-seals but the mounting plate is metal, not plastic. A conventional ring-type ultrasonic system delivers fast and quiet autofocus complete with full-time mechanical override, and a focus distance scale.
