Canon RF 45mm F1.2 STM is about to be released

Canon's new RF 45mm F1.2 STM full-frame lens is about to be released, with leaks suggesting image quality comparable to the Canon EF 50mm f/1.2L USM lens. It features a 67mm filter thread, a lightweight design, and weighs only 346 grams, offering a lightweight large-aperture prime lens option. It also boasts digital breathing correction and may pay homage to Canon's EF 50mm f/1.4 USM lens from thirty years ago. Patent information indicates the lens's actual focal length is 48.5mm, very close to 50mm, making it a budget-friendly version of the 50mm F1.2. Moreover, its extremely lightweight 346 grams is lighter than many brands' 50mm f/1.4 lenses.
