HONGKONG, 25^th November 2025 — Canon today officially launches the new affordable and compact ultra-fast f/1.2 standard RF Prime Lens, RF45mm F1.2 STM. The RF45mm F1.2 STM is a compact, lightweight and affordable option for users who desire bokeh. The 45mm focal length allows users to capture a natural perspective, while moving seamlessly between wide environmental shots and intimate close-ups—often with just a single step.

Ultra-Fast F1.2 Aperture for Every Occasion
RF45mm F1.2 STM provides large and bright f/1.2 aperture at an affordable price. The generous bokeh made possible by a large aperture lens allows users to create images with a three-dimensional look that makes subjects softly stand out. The RF45mm F1.2 STM’s extremely shallow depth of field at maximum aperture enables significant blur in the background, making subjects stand out. Background blur is smoother than with kit lenses or even the RF50mm F1.8 STM, giving images a natural, seamless look. Its 9-blade circular diaphragm also allows the user to enjoy a beautiful, almost circular bokeh effect when the aperture is stopped down slightly.

The 45mm focal length of RF45mm F1.2 STM is closer to human vision than the typical 50mm for standard lenses, enabling more natural angles of view and perspectives. The angle of view is slightly wider than a 50mm lens, making it suitable for portraits, snapshots, landscapes, and more. When mounted on an APS-C EOS R camera, the RF45mm F1.2 STM can be used as a medium telephoto equivalent to 72mm F1.2 (35mm full-frame equivalent). This provides the compression effect of a medium-telephoto lens as well as maintaining an ideal distance for capturing natural expressions of people, making it perfect for portrait photography. 

Diverse Photographic Capabilities
With the RF45mm F1.2 STM, imaging at wide-open aperture is distinctive and soft, letting users enjoy distinct photographic styles from the L Lenses which have higher resolution and sharpness. On the other hand, narrowing the aperture enables rendering with sharpness from the image center to the periphery. Aperture control for each setting or subject lets users enjoy wide-ranging photographic capabilities from a single lens.

The RF45mm F1.2 STM transforms everyday scenes into a cinematic masterpiece with breathtaking depth. Not only is it a compact prime lens that delivers creamy bokeh and crisp detail, but its fast f/1.2 aperture also excels in low light. The STM delivers fast accurate AF while the smooth and near-silent operation makes it perfect for video recording.

Intuitively Designed
RF45mm F1.2 STM features the largest-diameter PMo aspherical lens among RF lenses and uses electronic distortion correction on the camera side reduces the number of lens elements, making the optics more compact for a lighter and smaller design even with the wide f/1.2 aperture. Moreover, the use of Gear-type STM with electronic focus system enables a significantly smaller and lighter system over a Ring USM. The adoption of front focusing and fixed-length lens barrel design also enables the use of resin cam barrel instead of metal for a lighter f/1.2 lens. As a result, the RF45mm F1.2 STM it weighs only about 346g, with a length of approximately 75mm and a diameter of about 78mm even though it is an f/1.2 aperture lens. Its compact and lightweight design makes it easy to carry. A dedicated focus ring on the RF45mm F1.2 STM offers accurate manual focus for creative control. Canon's distinctive knurled control ring allows control over shutter speed, aperture, ISO and exposure compensation. Whether for street photography, travel, or everyday creative work, it is an ideal choice as a carry-around lens.
