4.4

$499as of Apr 25

The Canon EF 85mm f/1.8 USM remains a compelling budget-friendly option for portrait and low-light photography, praised by Digital Camera World and Ken Rockwell for its compact design, fast autofocus, and surprisingly sharp performance.

— Fast f/1.8 aperture allows for decent low-light performance and shallow depth of field effects

How they stack up

Canon EF 50mm f/1.8 STM

The Canon EF 50mm f/1.8 STM surpasses the Sony FE 50mm f/1.8 in terms of autofocus quietness and manual focus capability, but it's not as sharp as the Canon RF50mm F1.8 STM. Compared to the Canon EF 85mm f/1.8 USM, it lacks the telephoto reach and professional build quality, though it's more affordable and offers better low-light performance. It's the most balanced option for beginners but doesn't match the premium features of the RF50mm F1.8 STM or the telephoto capabilities of the 85mm lens.

Canon EF 85mm f/1.8 USM

The Canon EF 85mm f/1.8 USM provides the telephoto reach and portability that the Sony FE 50mm f/1.8 lacks, but it's significantly heavier and more expensive than the Canon EF 50mm f/1.8 STM. Compared to the Canon RF50mm F1.8 STM, it offers less advanced optical design and doesn't include the aspherical element, though it's more versatile for portrait work. It's the most versatile of the group for telephoto applications but lacks the image stabilization and weather-sealing found in higher-end L-series lenses.
