Canon rebuilt the optics of its classic 50mm f/1.8 for the RF mount, and the result punches well above its price. Digital Camera World praised it as 'everything you want a nifty fifty to be,' while Ken Rockwell noted its 'superb optics' and 'very close focussing.' It carries the first aspherical element in any Canon 50mm f/1.8 design since 1987, and sharpness holds up against the far pricier RF 50mm f/1.2L. Reviewers flagged the missing image stabilization and weather sealing, which points it at casual photographers and EOS R users who want an affordable standard lens rather than professionals who need heavy-duty build quality.

Strengths
  • Superb image quality with very sharp performance and no barrel distortion
  • World's closest-focussing non-macro 50mm lens at 0.3m minimum focus distance
  • First Canon 50mm f/1.8 with aspherical element for improved optics
Watch-outs
  • No image stabilization or weather sealing
  • No AF/MF switch or stabilization switch

S-line optical quality at a price that undercuts expectations is the Nikon Z 50mm f/1.8 S in one line. Reviewers consistently praise its remarkable sharpness, even shot wide open, along with excellent microcontrast and professional-grade weather sealing. Autofocus is fast and silent, which serves stills and video alike. There's no aperture ring and it's slightly heavier than budget alternatives, but the image quality rivals more expensive f/1.4 lenses. That puts it among the best nifty fifties for the Nikon Z system.

Strengths
  • Exceptional sharpness even wide open at f/1.8
  • Professional S-line build quality with weather sealing
  • Fast, silent autofocus reliable in diverse lighting
Watch-outs
  • No dedicated aperture ring
  • Slightly heavier than budget 50mm alternatives

How they stack up

Canon RF50mm F1.8 STM

The Canon RF50mm F1.8 STM outperforms the Sony FE 50mm f/1.8 with its first aspherical element and superior close-focusing distance, but it's not as compact as the Canon EF 50mm f/1.8 STM. Compared to the Canon EF 85mm f/1.8 USM, it lacks the telephoto reach and hood included, though it offers better overall image quality and more advanced optical design. It's the most technically advanced of the group but still lacks image stabilization and weather-sealing.

Nikon Z 50mm f/1.8 S

The Nikon Z 50mm f/1.8 S offers superior optical quality compared to the Canon EF/RF 50mm f/1.8 STM lenses, with S-line sharpness and weather sealing. Unlike the Sony FE 50mm f/1.8, it includes professional-grade build quality at a competitive price point.
