Canon EF 35mm F/1.4L II USM vs Canon EF 50mm F/1.2L USM — Which Is Better?

The Canon EF 35mm F/1.4L II USM and the Canon EF 50mm F/1.2L USM are full-frame prime lenses for the Canon EOS system, each carrying Canon's professional L-series branding. The 35mm arrived in 2015, eight years after the 2007 50mm, making it the newer design of the pair. Both cover full-frame sensors, so either one uses the complete sensor area on a full-frame EOS body.

The EF 50mm F/1.2L is the lighter, shorter carry: 580 g and 66 mm long, against 760 g and 105.5 mm for the EF 35mm F/1.4L II. The 35mm is the slimmer of the two at 80.4 mm wide versus 86 mm. Both lenses share the Canon EF mount and 72mm front filter threads, so one set of 72mm filters fits either lens directly.

Focal length does the practical work here: the 35mm frames more context for reportage and environmental portraits, while the 50mm gives a tighter perspective for classic head-and-shoulders portraits. The 50mm also offers the brighter maximum aperture at F/1.2 against F/1.4, which helps in candlelit interiors and evening street scenes.

The 35mm is the better close-up tool, focusing to 28 cm against 45 cm and reaching 0.21x magnification versus 0.15x, which suits tighter detail shots of food or flowers. Both are primes with autofocus, automatic diaphragms and manual focusing rings, so switching between them demands no change in shooting habit.

Fluorine coating is the useful extra on the EF 35mm F/1.4L II, helping the front element shed dust and fingerprints for quicker cleaning between shots. Both lenses are weather-sealed for shooting in rain or dust, and neither offers image stabilisation or teleconverter support. Without stabilisation on either lens, steady handheld technique matters at slower shutter speeds.

The EF 35mm F/1.4L II carries the more elaborate optical formula, with 14 elements in 11 groups, including a super-low-dispersion element aimed at reducing chromatic aberration in high-contrast scenes. The 50mm uses a simpler 8-element, 6-group construction. Both lenses include one aspherical element, and neither uses internal focusing.
