Canon RF-S 18-45mm f/4.5-6.3 IS STM Lens Summary

Arriving as one of two new native APS-C format RF lenses is the ultra-compact Canon RF-S 18-45mm f/4.5-6.3 IS STM Lens (together with the RF-S 18-150mm f/3.5-6.3 IS STM). It delivers a versatile focal width with a 1.6x crop factor for an equivalent focal zoom range of 29-72mm (full-frame format). This is great for a wide variety of subjects including landscapes, travel, portraits, vlogging and video, or simply as a general lens for all-day shooting.

Despite weighing just 130g, Canon has managed to add an image stabilisation mechanism, which gives you 4-stops of anti-shake compensation with the EOS R10, and up to 6.5-stops when mounted on the R7 camera, which has combined body/lens image stabilisation. A fast and silent STM (Stepping Motor) captures subjects quickly, whilst in-camera technology makes sure they stay in focus however fast they’re moving across the frame.

Key Features

  • New ultra lightweight APS-C format mirrorless zoom lens
  • Ideal for capturing photos and videos with a 29-72mm equivalent zoom range
  • Smooth, fast and quiet focusing motor
  • 4-stop lens based image stabilisation up to 6.5-stop combined with camera
  • Get as close as 15cm to your
  • Max 0.25x magnification for large details in your frame
  • Great quality results from two PMo Aspherical lens elements
  • Super compact 49mm filter thread to add lens filters
  • Super Spectra lens coating

Canon RF-S 18-45mm f/4.5-6.3 IS STM Lens in More Detail

Great first lens for exploring your creativity

Capture life wherever it takes you, with a compact APS-C zoom for crop sensor EOS R cameras that offers a 29-72mm (35mm equivalent) zoom range. That results in a compact zoom, which is ideal for travel, family snaps and even vlogging and can be easily stowed away in your kit bag.

Sharp handheld images and video

You won’t need a flash when you have 4-stops of image stabilisation built into the lens, with up to 6.5-stops of compensation on offer when used with compatible cameras.

Smooth, quiet focusing

Canon’s STM motor technology captures smooth, silent and accurate focusing while a seven blade, circular f/4.5-6.3 aperture is perfect for creating pleasing out of focus highlights and nice bokeh balls with the right conditions.

Manual focus option

Go into manual mode and get closer with a higher magnification in MF mode. This allows you get as close as to 15cm with a 0.25x magnification, as the perfect solution for capturing subjects in glorious detail.

Perfect for all-day shooting

The combined weight of this RF-S 18-45MM F4.5-6.3 IS STM and an EOS R APS-C mirrorless camera offers a significant weight savings compared to a DSLR equivalent. Less weight means you can use for longer, without getting tired and never missing a moment. Try this lens as the Canon EOS R10 with RF-S 18-45mm IS STM Lens kit to see precisely how light this combination can be.

Our Verdict

This is a great first zoom lens for anyone joining Canon’s newest APS-C format mirrorless camera system. The versatile zoom range is great for general shooting and you can capture a variety of subjects all with this one lens, including photos, videos and vlogs. It is extremely compact when retracted and weighs a featherweight 130g so you can add it to your bag without any worries. Despite this, the lens includes a fast and quiet STM (Stepping Motor) as well as image stabilisation system. This gives you 4-stops of camera shake compensation, ideal for lower lighting conditions when handholding. When mounted on compatible APS-C cameras, you’ll get up to an impressive 6.5-stops of combined IS with body stabilisation.

The 29-72mm zoom is made even more versatile thanks to a close minimum focus distance and high 0.25x magnification. This allows you to explore your creativity even further with dynamic angles and closer subjects, while also being very useful if you are vlogging. If you’re just joining Canon’s APS-C mirrorless system you can add this native RF-S 18-45mm f/4.5-6.3 IS STM as a standalone lens or in a kit combined with a camera. It makes a great starting point for creators to begin their journey and capture any lifestyle situation as a first versatile zoom.
