Aperture and Low Light Performance
The Tokina 33mm f/1.2 offers a significantly wider maximum aperture than the Canon RF 50mm f/1.8, providing better low-light performance and shallower depth of field capabilities. This makes the Tokina ideal for portrait work and creative bokeh effects, while the Canon's f/1.8 aperture is still quite fast for most shooting scenarios but won't match the extreme shallow depth of field potential.
Focal Length and Versatility
The Canon RF 50mm provides a classic portrait focal length on full-frame cameras, offering natural perspective for portraits and general photography. The Tokina 33mm on APS-C Fuji cameras delivers approximately 50mm equivalent field of view, making both lenses similar in practical use, though the Canon offers more flexibility across various shooting situations.
Build Quality and Features
Canon's RF 50mm f/1.8 STM features smooth, nearly silent autofocus motor ideal for video work and quiet photography situations. The lens construction is modern with good optical quality. The Tokina offers premium build quality with its wider aperture design, but lacks the advanced autofocus technology and overall system integration that Canon provides.
