General

The Canon EF 24-70mm F/2.8L II USM is a 2012 standard zoom for Canon EOS bodies, while the Sigma 24-70mm F/2.8 DG OS HSM Art followed in 2017, here in Nikon F mount. Sigma also produced this Art zoom in Canon EF fit, so EOS owners can consider both. Both are full-frame zooms covering the same 24-70mm range at a constant f/2.8, the classic wedding and travel formula.

Physical

The Canon is the lighter carry: 805 g against 1200 g for the Sigma, a 395 g difference. The Sigma is the more compact tube, 107.6 mm long and 88 mm across against 113 mm and 89 mm, so it takes slightly less room in a bag.

Both take the same 82 mm front filters, so a polariser or ND filter bought for one screws directly onto the other. Mount fit is fixed: the Canon is EF only, while the Sigma version compared here is Nikon F.

Optics

A single lens can carry a wedding from wide reception at 24mm to portrait at 70mm, and both hold a constant f/2.8 across that range. You keep the same maximum aperture while zooming, so neither lens trades speed for reach.

Close-up working distance is a near match: the Sigma focuses to 37 cm and the Canon to 38 cm. Both offer a 0.21x maximum magnification for detail shots of rings, food or flowers, and each uses an automatic nine-blade diaphragm.

Features

Optical stabilisation is the deciding feature difference, and it favours the Sigma. Its OS system is rated at 4 stops, support for handheld shooting in dim interiors and evening streets. The Canon offers no built-in stabilisation, so low-light handheld work needs faster shutter speeds or camera support.

Protection and cleaning are shared. Both lenses have weather sealing for outdoor work, and both carry a fluorine coating that helps the front element shed water, oil and smudges for quick field cleaning. A zoom lock on each stops the barrel creeping when carried.

Construction

The Sigma builds its image from 19 elements in 14 groups, against 18 in 13 for the Canon. Each design includes one aspherical element and one low-dispersion element aimed at reducing chromatic aberration, and the Canon adds one super-low-dispersion element. Neither uses internal focusing, so the barrel extends during focusing on both.

Verdict

For handheld shooting in low light, the Sigma is the stronger choice: its 4-stop OS supports dim interiors and evening scenes without a tripod, which the Canon cannot match. That benefit is worth its 395 g of extra weight for handheld work.

Choose the Canon EF 24-70mm F/2.8L II USM when weight matters most, such as long documentary days or hiking with one body, or when the work sits on a tripod and stabilisation goes unused. Nikon F shooters have one option in this pair: the Sigma.
