What's Included

The Canon RF 45mm f/1.2 STM delivers professional-grade optical performance in a remarkably compact form factor. Its exceptional f/1.2 aperture enables striking subject isolation and creamy bokeh rendering, while the 45mm focal length proves invaluable for portraiture, lifestyle photography, and challenging lighting conditions. The STM autofocus mechanism operates with near-silent precision, complemented by seamless manual focus override for critical focusing tasks. A single aspherical element within the optical formula effectively suppresses spherical aberrations and distortion across the frame. Whether capturing intimate studio work or candid moments in natural light, this lens combines optical sophistication with practical versatility and user-friendly operation.
