Canon 45mm f/1.2 STM 45mm
The f/1.2 aperture delivers extremely shallow depth of field and strong low-light capturing ability in a weather-sealed 821g body, complemented by near-silent STM autofocus. A refined optical design suppresses chromatic aberration for consistent edge-to-edge sharpness, while the robust RF-mount construction includes a smooth manual focus ring for precise control. This lens suits portrait photographers needing dramatic subject isolation and videographers who depend on silent, accurate focus tracking.
