Canon EF 24mm F/1.4L II USM vs Canon EF 35mm F/1.4L II USM — Which Is Better?

The Canon EF 24mm F/1.4L II USM and the Canon EF 35mm F/1.4L II USM are second-generation L-series primes for Canon EOS full-frame bodies. Both use the EF mount, so either fits the same cameras without adaptation. The useful difference is perspective: the 24mm, from 2008, frames wide scenes, while the 35mm, from 2015, gives a tighter, more natural view of people and interiors. Both open to F/1.4 for dim rooms and evening streets.

The 24mm is the lighter and more compact carry at 650 g and 87 mm long, against 760 g and 105.5 mm for the 35mm, though its 94 mm barrel is fatter than the 35mm's 80.4 mm front. Both accept front filters, so polarisers and ND filters remain straightforward options.

The filter threads differ: 77 mm on the 24mm and 72 mm on the 35mm, so an existing filter fits only its matching lens directly.

The 24mm covers architecture, sweeping landscapes and star-filled skies, while the 35mm suits reportage and environmental portraits with its tighter framing. Both open to F/1.4, so night streets and candlelit rooms get the same wide-aperture control from either.

For close work, each lens offers its own strength. The 24mm focuses to 25 cm, slightly closer than the 35mm's 28 cm, while the 35mm reaches 0.21x magnification against the 24mm's 0.17x, filling more of the frame with a small detail. Both offer autofocus with a manual focusing ring for fine adjustments.

The 35mm II has a fluorine coating on its front element, which repels dust and smudges and wipes clean easily, a genuine convenience when switching lenses in the field. The 24mm II does not have this coating. Both lenses are weather sealed, and neither offers image stabilisation, so shutter speed and technique carry the load in low light.

The 2015-era 35mm II carries more special glass in its 14-element, 11-group design, with one super-low-dispersion element and one CA-reduction element working to limit colour fringing in high-contrast frames. The 2008-era 24mm II, built from 13 elements in 10 groups, instead uses a floating element system, adjusting internal groups as you focus to help maintain quality across its focusing range.

The shared specifications are narrower here: each lens uses one aspherical element and one low-dispersion element, and neither uses internal focusing.
