RF 45mm F1.2 STM overview
The Canon RF 45mm F1.2 STM is a 45mm f/1.2 prime for full-frame cameras on Canon RF, announced by Canon in November 2025. 23 cameras we track take it without an adapter.
Going by its spec sheet, it suits low light. It is a weaker pick for rain and dust as well as close-ups.
New, it sells for A$530.70 to A$699.95 at the 5 stores we track in Australia that have it in stock; used and refurbished copies start at A$462. Over the last 90 days it has usually cost A$531 to A$563 new.
Worth comparing it with the Canon RF 50mm F1.2L USM, Canon RF 50mm F1.4L VCM and Voigtländer Nokton 40mm F1.2 Aspherical.
