Description
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 F1.2 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.
What You See, I See
The 45mm focal length is like seeing how you see with the naked eye, giving you a natural perspective and framing that feels just right.
Control at Your Fingertips
A dedicated customizable control ring on the front of the lens lets you assign functions like ISO, White balance, etc. for quick adjustments during shooting.
