Physical

For a lighter bag, the Canon is the better pick: it weighs 795 g against 1200 g for the Sigma, a 405 g difference. The Sigma is slightly shorter at 107.6 mm versus 118 mm, but its 88 mm diameter exceeds the Canon's 83.5 mm.

Both lenses accept front filters. Their threads differ, though: the Canon takes 77 mm filters and the Sigma takes 82 mm, so each needs its own direct-fit size.

Optics

The Sigma is the stronger choice for dim venues and shallow depth of field, because it holds a constant f/2.8 aperture across its zoom range. The Canon stays at f/4 throughout.

The Canon fights back with reach, zooming to 105mm against the Sigma's 70mm, which tightens portraits and distant subjects without changing lenses. Both start at 24mm. The Sigma focuses closer, to 37 cm versus 45 cm, while the Canon offers the higher maximum magnification at 0.24x versus 0.21x.

Features

Both lenses offer the same field-ready features. Each is weather sealed, each carries a fluorine coating that makes the front element easier to wipe clean, and each has a zoom lock against creep. Neither supports teleconverters.

Stabilization is also shared, and both lenses carry a 4-stop rating. Autofocus and a manual focusing ring are available on each.

Construction

The Sigma is the more complex design, built from 19 elements in 14 groups against the Canon's 17 elements in 12 groups. Part of that construction is a low-dispersion element, which serves to reduce chromatic aberration, a type the Canon does not include. Both use a single aspherical element.

Neither lens uses internal focusing, so the barrel moves during focus on both. Each relies on a rotary zoom ring with a manual mechanism, giving the same zooming style.

Verdict

Choose the Sigma 24-70mm F/2.8 Art for weddings, indoor events or evening street work, where its constant f/2.8 aperture admits more light and isolates subjects better than the Canon's f/4. Nikon F shooters get it natively, and Canon EOS shooters can buy the Canon EF version.

Choose the Canon EF 24-105mm F/4L IS II if you want one lighter travel lens that reaches 105mm for portraits and distant detail at 795 g. The Sigma here is the Nikon F version, so confirm the mount before buying.
