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

The Canon EF 35mm F/1.4L II USM and the Canon EF 50mm F/1.4 USM are both full-frame prime lenses for Canon EOS cameras, so either one mounts directly on the same EF bodies. Both are fixed-focal-length designs rather than zooms. The 35mm is the 2015 second-generation L-series version, while the 50mm dates back to 1993, making it the far older design of the pair.

The EF 50mm F/1.4 USM is the far more compact option, weighing 290 g against 760 g for the 35mm and measuring 51 mm long versus 105.5 mm. That makes the 50mm the easier lens to keep in a bag as an everyday standard.

Both take front filters, but in different direct-fit sizes: 58 mm for the 50mm and 72 mm for the 35mm. Filters will not transfer between them without a step ring.

Focal length is the real buying choice here: the 35mm suits environmental portraits, interiors and reportage where you want context, while the 50mm gives a tighter, classic standard view for head-and-shoulders work.

A shared F/1.4 maximum aperture means both lenses let you shoot wide open in dim light. For small subjects, the 35mm is the stronger choice. It focuses to 28 cm against 45 cm for the 50mm, and its maximum magnification reaches 0.21x against 0.15x.

The 35mm offers two practical protections the 50mm lacks: weather sealing for shooting in rain or dust, and a fluorine front coating that helps repel water and oil so the front element wipes clean easily.

Neither lens offers image stabilization, so steady handheld shooting at slower shutter speeds depends on technique. Neither supports teleconverters.

The 35mm L II carries the more elaborate correction design, with 14 elements in 11 groups including an aspherical element, plus low-dispersion and super-low-dispersion glass to control aberrations. The 50mm is a simpler 1993 design, with 7 elements in 6 groups and two elements aimed at reducing chromatic aberration.

Both lenses use conventional barrel extension for focusing rather than an internal focusing system, so the barrel moves as focus changes.
