Canon RF 45mm F1.2 STM Lens

Redefine low-light versatility and shallow depth-of-field artistry with the Canon RF 45mm F1.2 STM Lens. Offering a natural perspective close to the human eye, this prime lens pairs an ultra-bright f/1.2 maximum aperture with an agile, lightweight build weighing under 400g. Designed specifically for Canon EOS R system cameras—from full-frame bodies like the EOS R6, EOS R8, and EOS R5 series to Super 35 cinema rigs—it produces silky background bokeh, isolates subjects with precision, and excels in ambient-light environments without weighing down your kit bag.

Key Features:

• Ultra-Bright f/1.2 Aperture: Capture handheld shots in low light and achieve dramatic subject isolation with cinematic background separation and shallow depth of field.
• Sub-400g Portable Build: Engineered as an ultra-compact f/1.2 autofocus prime in the Canon RF lineup to weigh under 400g, making it ideal for all-day street, travel, and event shoots.
• Natural 45mm Perspective: Sits in the sweet spot between standard 35mm and 50mm focal lengths, delivering natural proportions for environmental portraiture, editorial work, and documentary street photography.
• Smooth & Quiet STM Autofocus: Stepping Motor (STM) technology delivers fast, silent autofocus acquisition for still photography and smooth focus transitions during video recording.
• 9-Blade Circular Aperture: Produces circular, pleasing bokeh highlights and soft out-of-focus background blur across portrait and detail shots.
• Dedicated Focus and Control Rings: Independent rings provide precise manual focus override alongside customizable exposure adjustment (ISO, shutter speed, or aperture) straight from the lens barrel.
• Durable Metal Lens Mount: Built with a reinforced metal bayonet mount ensuring long-term reliability and rigid alignment on active production shoots.
