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 S$599 in Singapore (Canon Store).

Worth comparing it with the Canon RF 50mm F1.2L USM, Canon RF 50mm F1.4L VCM and Voigtländer Nokton 40mm F1.2 Aspherical.
