Canon's RF-mount ultra-fast standard prime — f/1.2 at 45mm with STM motor for hybrid shooting.

The Canon RF 45mm f/1.2 STM was released in early 2026 as an accessible f/1.2 prime for the Canon RF mirrorless system. The 45mm focal length places it between the standard 50mm and wide 35mm positions — a slightly wide-normal perspective favoured for documentary and environmental portrait work. STM (gear-type stepper motor with magnetic detection) provides smooth, quiet autofocus suited to video. Post-August 2025 knowledge cutoff; specs confirmed from Canon official.

9 elements in 7 groups including one PMo aspherical element. f/1.2 maximum aperture. 9-blade circular aperture. STM autofocus. 67mm filter thread. 346g. Minimum focus distance 0.45m. Maximum magnification 0.13x. Dimensions: 78mm diameter × 75mm length. Full-frame Canon RF coverage. No optical image stabilisation. No weather sealing.

At 346g and 67mm filter thread, the RF 45mm f/1.2 STM is notably compact for an f/1.2 full-frame prime — lighter than the RF 50mm f/1.2L USM (950g) and without the L-series' higher build standard and IS. The STM motor provides quieter, smoother focus during video recording than Canon's older DC motors, though AF tracking speed is below the faster Nano USM or RF motor systems used in L-series glass. No weather sealing distinguishes it from the L-series premium tier.

On the used market the Canon RF 45mm f/1.2 STM is an early 2026 product; used availability will be limited initially. Condition checks: STM AF response and speed, f/1.2 front element for marks, 67mm filter thread, aperture blade condition at f/1.2. Compatible with all Canon RF-mount full-frame and APS-C bodies.
