Product Description
Compact, lightweight, and versatile, the Canon RF 45mm f/1.2 STM is an affordable prime lens that combines an ultra-fast f/1.2 aperture with a practical 45mm focal length. Ideal for everything from casual walks to studio sessions, it delivers beautifully shallow depth of field and smooth, expressive bokeh. Its wide aperture makes it especially well-suited for portraits, lifestyle photography, and low-light shooting, producing soft, atmospheric images with pleasing focus falloff. The STM motor ensures fast, quiet, and precise autofocus with full-time manual focus control, while one aspherical element minimizes spherical aberrations and distortion for impressive clarity.
