General

The Canon EF 16-35mm F/2.8L III USM and the Canon EF 24-70mm F/2.8L II USM are both L-series full-frame zooms for the Canon EOS system, but they answer different shooting needs. The 16-35mm III, released in 2016, is the ultra-wide tool for architecture, landscapes and cramped interiors. The 24-70mm II, from 2012, is the standard-range workhorse for events, portraits and general assignments. Both share the Canon EF mount, so either fits the same EOS bodies.

One 82mm filter set fits both lenses directly, so a shared polariser or ND collection serves either. The 24-70mm weighs 805g against 790g for the 16-35mm, a 15g difference that keeps them in the same weight class. The 16-35mm is the longer barrel at 127.5mm against 113mm, and diameters nearly match at 88.5mm and 89mm.

The 16-35mm III is the pick for ultra-wide work, and the 24-70mm II wins standard-range flexibility, so focal range decides this purchase. The 16-35mm starts at 16mm against 24mm, wide enough to fit whole buildings and interiors. The 24-70mm reaches 70mm, twice the 16-35mm's longest setting, for portraits and tighter event framing. A similarity helps both in dim venues: each holds f/2.8 across its zoom range.

The 16-35mm focuses closer, 28cm against 38cm, so you can work nearer to a foreground subject. Its maximum magnification is also higher, 0.25x versus 0.21x, handy for filling the frame with a close subject. Its internal zoom keeps barrel length constant while framing.

Features

Weather sealing on both lenses suits them to outdoor shooting, and the fluorine coating on each front element wipes clean easily. A useful difference appears when carrying the camera: the 24-70mm has a zoom lock that stops the barrel creeping downward on a strap, while the 16-35mm does not. Neither offers image stabilisation or teleconverter compatibility.

Construction

The 16-35mm III carries more aspherical correction for its wide-angle view, with three aspherical elements including two bi-aspherical types, plus two low-dispersion elements in a 16-element layout. The 24-70mm II answers with 18 elements in 13 groups, including one super-low-dispersion element. The 16-35mm also uses internal focusing, so the barrel does not extend while focus moves, which helps when working close to a subject.

Verdict

Choose the 16-35mm III for ultra-wide work: architecture, landscapes, interiors and night skies at 16mm and f/2.8. Choose the 24-70mm II when one lens must cover a whole event, from group scenes at 24mm to portraits at 70mm. Both share the constant f/2.8 aperture, weather sealing, fluorine coating and 82mm filter thread, so neither gives up the core L-series toolkit. The focal range your subjects demand should decide.
