Canon Introduces RF-S10-18mm f/4.5-6.3 IS STM, a Compact Ultra-Wide Zoom Lens for APS-C Cameras


Canon today announced the RF-S10-18mm f/4.5-6.3 IS STM, a new ultra-wide-angle zoom lens designed for APS-C EOS R cameras. Compact and lightweight to match APS-C camera bodies, it has a smaller footprint compared to its EF-S and EF-M counterparts. Its 16mm to 29mm full-frame equivalent focal range offers ultra-wide coverage ideal for travelogs, selfies, and shooting in tight spaces.

Canon Revolutionary RF S10 – 18mm:

The RF-S10-18mm f/4.5-6.3 IS STM is the first lens in the RF-S series, which is dedicated to APS-C cameras. The lens features an innovative optical design and configuration that leverages the advantages of the RF mount, delivering exceptional image quality across the entire frame, including the edges. The lens also uses two Ultra-Low Dispersion (UD) elements to reduce chromatic aberrations and enhance clarity. Another unique feature of the RF-S10-18mm f/4.5-6.3 IS STM is its ability to achieve a magnification of up to 0.5x at the 10mm end, with a minimum focusing distance of 0.086m. This allows users to create stunning close-ups with an ultra-wide perspective, adding a new dimension to their creative expression.

For video shooting, Optical IS coordinates with in-camera Movie Digital IS to achieve steady, natural footage for shooting while walking, so you can film your travelog with minimal equipment. Three-way Coordinated Control IS with In-Body IS-equipped cameras further enhances the effect.

Unique Ultra Wide -angle:

Taking close-ups of small objects with background details is possible with the lens’ 0.14m closest focusing distance throughout the entire focal range, which achieves a maximum magnification of up to 0.23x when autofocus is enabled. One can turn off the AF at the 10mm mark to shoot even closer (closest focusing distance: 0.086m) and achieve half-macro (0.5x max. magnification) shots with the unique Centre Focus Macro effect.

Despite its lightweight body, the RF-S10-18mm f/4.5-6.3 IS STM delivers image quality that surpasses its bigger EF-S counterpart. The RF mount’s short back focus enables a lens configuration that optimizes image quality while minimizing the number of elements, keeping ghosting, chromatic aberration, and color blurring well under control. Ornate details are rendered in crisp quality all the way to the edges.

Canon RF S10

The RF-S10-18mm f/4.5-6.3 IS STM weighs only 150g and is so light that you might not notice it attached to your camera. The featherweight ultra-wide angle lens allows easy self recording without the need for selfie sticks. It is the perfect companion for those looking for lighter equipment. 

Wide Perspective Angle

At approximately 44.9mm long and 69mm wide, you will be able to keep the camera into your small bag without needing to detach the lens. 

Autofocus is driven by a leadscrew-type STM (stepping motor), which enables smooth, seamless focus transitions during video recording. The lens also supports Focus Breathing Correction, which digitally corrects the distracting changes in angle of view caused by focus movement when recording video.

The RF-S10-18mm f/4.5-6.3 IS STM provides up to 4 stops of image stabilisation with its in-built Optical Image Stabilizer.

Full Frame and APS-C

When used with compatible cameras that have In-Body Image Stabilizer, the Coordinated Control IS achieves up to 6 stops of image stabilisation, perfect for those handheld low-light shots that usually require a tripod.
