Compact and lightweight, the Canon RF 45mm f/1.2 STM is an economical prime lens featuring an impressively fast f/1.2 maximum aperture and a versatile 45mm focal length. Ideal for leisurely strolls in the park or a productive day in the studio, this lens provides an exceptionally shallow depth of field along with stunning, expressive bokeh. With its wide-aperture capabilities and medium focal length, this lens excels in capturing portraits, lifestyle content, and performing well in low-light conditions, producing soft images with striking focus falloff. An STM motor ensures quiet and smooth autofocus performance, complemented by full-time manual focus override. The optical design includes one aspherical element, which effectively minimizes spherical aberrations and distortion.
