Canon RF-S 10-18mm f/4.5-6.3 IS USM Lens Summary

Thanks to an ultra wide angle zoom range, the Canon RF-S 10-18mm f/4.5-6.3 IS USM Lens lets you get more in the shot, even when you can’t stand back from your subject. With its crop-format RF-S design, the zoom lens is ideal on crop sensor Canon mirrorless cameras such as the EOS R7 or R10, and it also complements the lightweight R50 camera perfectly.

The wide angle field of view is equivalent to 16-29mm (full-frame format), which lends itself to landscape photography, travel, video making and vlogging in particular. What’s more, this RF-S lens includes 4-stops of image stabilisation (IS), which increases to 6-stops when combined with camera IBIS found in the R7 and other models. Stabilisation is extremely effective when you want to handhold the camera and capture images and movies without needing a tripod, and is effective for shooting during low light situations.

Canon has included an STM motor (stepper motor) in the zoom lens, which delivers smooth, fast and quiet autofocus, ensuring your subject stays sharp, even when it’s moving around across the frame. The RF-S 10-18mm f/4.5-6.3 also features a high 0.5x magnification, which allows you to capture stunning close-ups, explore dynamic compositions and record vlogs more easily.

You can customise the manual focus / control ring to change settings on the camera like ISO, shutter speed, aperture or exposure compensation, which helps streamline and speed up your workflow.

Key Canon RF-S 10-18mm f/4.5-6.3 IS USM Lens Features

  • Compact and lightweight ultra wide angle zoom lens for crop format mirrorless cameras

Canon RF-S 10-18mm f/4.5-6.3 IS USM Lens in More Detail

Get more in the frame

This lens’ ultra wide field of view is used to capture epic scenery, city shots and video, where you want to get more of the scene into each frame, without standing back from the subject. Whether you’re shooting inside a building, on the street, or hiking to wild landscapes the RF-S 10-18mm is the perfect ultra wide angle lens to nail every shot.

You can use it to record yourself and plenty of the background while vlogging, capture group shots of family and friends all together, and even make movies which invite the viewer to step into your storytelling world.

Up to 6-stops image stabilisation

Regardless of its compact and lightweight design, the Canon RF-S 10-18mm lens includes built-in optical image stabilisation (IS), which reduces camera shake by 4-stops, or up to 6-stops when combined with camera body stabilisation (IBIS).

Stabilisation is especially useful when working in low light, while walking and recording video during a vlog, or when making a movie, helping to keep your photos and videos sharper, smoother and clearer.

Fast and quiet focus

Smooth, fast and quiet focus is ideal when recording video and capturing photos where you don’t want to disturb the subject with unnecessary noise. Canon has utilised their effective and quiet STM focus technology in the ultra wide RF-S 10-18mm f/4.5-6.3 IS STM zoom lens, ensuring you come away with sharp results more often, even when the subject is moving around.

The Stepper Motor (STM) delivers quiet, smooth focusing, making it ideal for filming, while still being great for photography.

Customisable control ring

Following the trend of other Canon mirrorless lenses, this model also offers a combined manual focus ring and control ring, which can be customised to change camera settings without taking your hand off the lens. The feature can be invaluable when you want to adjust anything such as focus, ISO or exposure compensation on the fly, without interrupting the shot by looking at the camera menu.

Compact design with high image quality

At just 150g this is one of the lightest ultra wide angle zoom lenses available, yet it captures high image quality thanks to Canon’s effective mirrorless optical design. A combination of Plastic-moulded (PMo) aspherical lens elements and UD (ultra-low dispersion) elements are responsible for maintaining great image and video quality, while reducing weight when compared with heavy glass elements found in other models.

When retracted, this lens measures just 44.9mm long, making it the ideal candidate for travel and easy transportation, in even the smallest camera setup. In fact it’s smaller than equivalent DSLR lenses, a mirrorless with adapted lens or just about any other model available from Canon.

Our Verdict

Whether you shoot with a DSLR or mirrorless camera there’s no comparison to this newly developed RF-S 10-18mm f/4.5-6.3 IS STM lens from Canon. It is significantly smaller and lighter than virtually any other ultra wide angle zoom lens of this calibre, regardless of whether adapted onto mirrorless, or native RF format.

The focal length is useful for all sorts of genres, from travel and landscapes to cityscapes, vlogging and video recording. The lens can get very close to the subject and also provides a high 0.5x magnification, enabling you to fill the frame and capture beautiful close-ups with precisely the details you want from the scene.

Although it is small and lightweight, this ultra wide zoom lens comes with built-in optical image stabilisation, which is rated at 4-stops. If you have a compatible camera with IBIS, this rises up to 6-stops, providing exceptionally stable results for handholding and capturing stills or video.

A new optical design has been incorporated into the RF-S 10-18mm lens, which renders high image quality while retaining lightweight qualities. Not only can you get more in the frame with this zoom, but subjects look clear and consistently sharp.

It’s been a while coming but crop sensor mirrorless camera users now have an excellent ultra wide angle zoom lens to add to their kit bag, which is perfect for a multitude of stills and video subjects.
