Features

Light and Affordable

The RF45mm F1.2 STM combines a large RF mount with a short back focus and advanced digital correction. A compact, affordable lens that still delivers the stunning F1.2 performance you expect.

Fastest Wide Open

The wide f/1.2 aperture creates stunning bokeh, making subjects pop with a three-dimensional effect. And thanks to the fast aperture, it shines in low light, allowing you to capture action at faster shutter speeds.

Tech, Meet Optics

Canon’s first use of a PMo aspheric lens in an F1.2 design helps minimize aberrations for sharper, more accurate images. Combined with the RF mount’s large diameter and short back focus, this allows for a compact build without sacrificing optical performance.

Step in and Focus with Confidence

The RF45mm F1.2 STM uses a gear-type STM motor paired with a magnetic detection system for smooth, precise autofocus. This keeps the lens compact and lightweight while ensuring your subject stays sharp, even in challenging lighting or fast-paced shooting.
