Ranked #5 in Best Portrait Lenses Under $500

Sony FE 50mm f/1.8

4.2

$196as of Apr 25

The Sony FE 50mm f/1.8 fills a gap in Sony's E-mount lineup with an affordable, compact 50mm prime lens. Digital Camera World praised its smooth bokeh and good image quality, while Photography Blog noted its lightweight design and plastic build quality. However, both reviewers highlighted significant vignetting at wide aperture and audible autofocus noise, with the latter being particularly problematic for videographers. The lens lacks weather-seals and internal stabilization, making it best suited for still photography enthusiasts seeking an entry-level fast prime rather than professionals requiring robust performance in challenging conditions.

Strengths

— Compact and lightweight at 186g with 68.6mm diameter
— Smooth bokeh quality with 7-blade circular aperture
— Good image quality with minimal chromatic aberrations

Watch-outs

— Severe vignetting at f/1.8 aperture
— Audible autofocus motor noise during operation
— No weather-seals or internal image stabilization

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.

Sony FE 50mm f/1.8

The Sony FE 50mm f/1.8 stands out for its compact design and affordable price, but it falls short compared to the Canon RF50mm F1.8 STM in terms of optical quality and close-focusing capability. Unlike the Canon EF 50mm f/1.8 STM, it suffers from severe vignetting and audible autofocus noise, making it less suitable for videographers. While it's lighter than the Canon EF 85mm f/1.8 USM, it lacks the telephoto reach and professional build quality that would make it competitive with higher-end options.
