Canon announced RF-S10-18mm f/4.5-6.3 IS STM for APS-C EOS R Cameras, together with 2 other Canon RF lenses, the RF24-105mm f/2.8L IS USM Z professional lens and RF200-800mm f/6.3-9 IS USM lens. For Canon APS-C EOS R cameras owners, they would now have a new ultra-wide Angele zoom lens designed for their usage, it is compact and lightweight, perfect for APS-C camera bodies. This lens also has a sampler footprint compared to its EF-S and EF-M counterparts. The 16mm to 29mm full-frame equivalent focal range offers ultra-wide coverage ideal for travel vlogs, selfies and shooting in tight spaces.

“With the increasing demand for our EOS R system, we are dedicated to broadening our cost-effective APS-C EOS R offerings. The introduction of the RF-S10-18mm f/4.5-6.3 IS STM enables APS-C EOS R photographers to span a comprehensive focal length, from ultra-wide to telephoto. This versatile lens is not only affordable but is also perfect for diverse settings, from indoor photography to landscapes and even vlogging. We anticipate it becoming a popular choice for many enthusiasts.” Said Edwin Teoh, Head of Marketing, Singapore Operations, Canon Singapore.

A Pint-sized Lens for Travel and Handheld Vlogging 

The RF-S10-18mm f/4.5-6.3 IS STM lens is just 44.9mm long when retracted and weighs only around 150g, this lens is around 40% shorter and lighter than its EF mount counterpart, the EF-S10-18mm f/4.5-5.6 IS STM (approx.72mm, 240g), and trumps even the nifty EF-M11-22mm f/4.5-5.6 IS STM (approx.58.2mm, 220g) in portability. Its size makes it easy to stabilise during handheld vlogging, with its ultra-wide angle of view capturing both the vlogger and surrounding scenery in the same frame, rendering a selfie stick unnecessary. 

Its featherweight and tiny size also makes it a convenient addition to a travel camera kit. While you may barely feel its weight on hikes and long walks, it will certainly come in handy for capturing the stunning view that awaits!

Sharp, Steady Images Even in The Dark

The RF-S10-18mm f/4.5-6.3 IS STM delivers sharper, steadier images even in low light condition. With built-in Optical Image Stabilizer (Optical IS), camera shake can be reduced by up to 4 shutter speed stops’ equivalent (1), so images are less likely to be blurry even when the shutter speed slows. When combined with a camera with In-Body IS such as the EOS R7, Coordinated Control IS enhances the effect to up to 6 stops’ equivalent (2).

For video shooting, Optical IS coordinates with in-camera Movie Digital IS (3) 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 Wide-angle Close-ups

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.

Crisp Image Details Up to The Edges

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 optimises image quality while minimising the number of elements, keeping ghosting, chromatic aberration, and colour blurring well under control. Ornate details are rendered in crisp quality all the way to the edges. 

Optimised Focusing

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.

Pricing and Availability

The Canon RF-S10-18mm f/4.5-6.3 IS STM will be launched at the recommended retail price of $529. The availability for this lens will be advised at a later date.
