Canon RF45mm F1.2 STM 45mm
The f/1.2 maximum aperture delivers exceptionally shallow depth of field and strong low-light performance in a compact 345g body, enabled by Canon’s first PMo aspheric lens in this design. Its natural 45mm perspective pairs with a customizable control ring and smooth STM autofocus, offering an affordable entry to ultra-fast RF glass. This lens is best for portrait and lifestyle photographers who want dramatic bokeh and a natural field of view without the bulk or cost of larger f/1.2 primes.
