The Canon RF 45mm f/1.2 STM Lens is a bright standard prime lens designed for Canon EOS R mirrorless cameras. It delivers exceptional low-light performance, strong background separation, and a natural perspective, making it ideal for portrait, street, and creative photography.
Natural 45mm Perspective
With a 45mm focal length, this lens provides a natural and realistic field of view that closely matches human vision. It is well-suited for everyday photography, portraits, and documentary-style shooting.
Ultra-Bright f/1.2 Aperture
The extremely fast f/1.2 aperture allows excellent performance in low-light conditions and enables strong subject isolation. It produces a smooth, creamy background blur (bokeh), helping subjects stand out with a professional look.
Compact Large-Aperture Design
Despite its large f/1.2 aperture, the lens is designed to remain compact and affordable. The large-diameter mount and short back focus design contribute to its efficient and lightweight construction.
Beautiful Bokeh Rendering
The lens is optimized for attractive background blur, allowing photographers to create images with a strong sense of depth and separation between subject and background.
Improved Optical Performance
A PMo aspheric lens element helps reduce optical aberrations and improve overall sharpness and clarity. Digital distortion correction further enhances image quality across the frame.
Fast Shutter Performance in Low Light
The f/1.2 aperture allows faster shutter speeds in dark environments, helping reduce motion blur and improve handheld shooting performance.
STM Autofocus System
The STM motor provides smooth, quiet, and reliable autofocus, making it suitable for both still photography and video recording.
