RF15-30mm f/4.5-6.3 IS STM: Get a Wider Perspective

2022-07-12

2.04 k

On 12 July 2022, Canon announced the RF15-30mm f/4.5-6.3 IS STM , a new ultra-wide-angle zoom lens for the RF mount. Also the first non-L lens of its kind, the lens promises to provide both the versatility of a wide-angle zoom lens and the excellent image quality of the RF mount at a wallet-friendly price.

In this article:

Key features

RF15-30mm f/4.5-6.3 IS STM at a glance

- Ultra-wide-angle zoom lens

- 0.52x macro capabilities; close-ups up to 12.8cm closest focusing distance (MF mode)
- Optical IS: up to 5.5 stops; with Coordinated Control IS: up to 7 stops

How will the RF15-30mm f/4.5-6.3 IS STM add to my lens choices?

A budget-friendly ultra-wide-angle zoom for the RF mount

Before the arrival of the RF15-30mm f/4.5-6.3 IS STM, Canon had two ultra-wide-angle zoom lenses native to the RF mount: the RF14-35mm f/4L IS USM and RF15-35mm f/2.8L IS USM. Part of the f/4L and f/2.8L lens trinities respectively, these professional grade lenses are popular for their excellent image quality and build, but come with a price to match. With the non-L-series RF15-30mm f/4.5-6.3 IS STM, users with a smaller budget now have an excellent option if they want a good ultra-wide-angle zoom lens to expand their arsenals.


From APS-C to full-frame: A lens trinity that you can grow with

When combined with the existing RF24-105mm f/4-7.1 IS STM and RF100-400mm f/5.6-8 IS STM, you get a reasonably-priced lens trinity that covers a very large 15mm to 400mm focal length range in full-frame equivalent terms. On APS-C cameras like the EOS R7 and EOS R10, the RF15-30mm f/4.5-6.3 IS STM offers an angle of view equivalent to 24 to 48mm in full-frame equivalent terms, which means a range of 24mm to 640mm on all three lenses. The best thing is that you can still use them if you decide to upgrade to a full-frame EOS R camera later on—and then, not only would you be able to shoot without the crop factor, you can also continue to enjoy shooting with the full image sensor resolution!

How will this lens change my images?

A wider view of the scene with the dynamic ultra-wide-angle perspective

The biggest draw of the RF15-30mm f/4.5-6.3 IS STM is the dynamic look you can get at the 15mm wide end. This not only captures a larger area of grand landscapes unfolding before your eyes, but also provides a dynamic perspective that can be leveraged to create images with greater impact. Zooming in to the 30mm long end gives you an angle of view that is a traditional favourite for street and everyday photography, easily allowing for natural-looking compositions with good balance between the subject and surrounding context.

15mm (full-frame camera)
The lens captures a lot of background context, making it useful for travel, lifestyle, and environmental portraits.

30mm (full-frame camera)
This is the traditional wide-angle angle of view, and creates natural-looking snapshots and everyday portraits.


Coverage at the 15mm wide end

Full-frame camera: 15mm

APS-C camera: equivalent to 24mm


Coverage at the 30mm long end

Full-frame camera: 30mm

APS-C camera: equivalent to 48mm

Can I use the RF15-30mm f/4.5-6.3 IS STM on my APS-C camera?

A handy standard zoom lens on APS-C cameras

The RF15-30mm f/4.5-6.3 IS STM can be attached to APS-C EOS R cameras like the EOS R7 and EOS R10 without a mount adapter. It provides a 24mm to 48mm equivalent angle of view—slightly wider than the RF-S18-45mm f/4.5-6.3 IS STM. The 48mm equivalent angle of view at the long end falls in the standard range, and provides a natural perspective well-suited for portraiture.

How close-up can I shoot with the RF15-30mm f/4.5-6.3 IS STM?

Up to 0.5x magnification: Semi-macro capabilities

When autofocusing (AF) is enabled, the RF15-30mm f/4.5-6.3 IS STM has a closest focusing distance of 0.28m across its entire zoom range, and a maximum magnification of 0.16x at the 30mm end. Switch to manual focus (MF) mode and its close-up abilities increase to as much as 0.52x, with a closest focusing distance of 0.128m at the 15mm wide end. Get closer and boldly fill more of the frame with flowers and other tiny objects or details you encounter!

Does RF15-30mm f/4.5-6.3 IS STM have image stabilisation?

Up to 7 stops’ image stabilisation with Coordinated Control IS

The RF15-30mm f/4.5-6.3 IS STM is equipped with the Optical Image Stabilizer (Optical IS) that achieves up to 5.5 shutter speed stops’ equivalent image stabilisation*. When combined with a camera with the In-Body Image Stabilizer (In-Body IS), such as the EOS R5 or EOS R6, the Optical IS and In-Body IS coordinate to perform Coordinated Control IS, which achieves enhanced image stabilisation of up to 7 shutter speed stops’ equivalent*.

You may have learnt that to ensure sharp images, the shutter speed should be set no slower than 1/x, where x is the focal length used. In other words, you can go as slow as 1/15 second when shooting at 15mm and still avoid camera shake. This causes many photographers to believe that image stabilisation is unnecessary on ultra-wide-angle lenses, but then again, imagine the possibilities that open up when you can shoot slower! For one, you can get cleaner, low ISO speed images in low light. For another, there’s creativity and mobility: you can try slow shutter photography handheld at shutter speeds that previously required a tripod, without sharpness being affected by camera shake.

One creative slow shutter photography technique that’s easy to do (but takes practice to perfect) is panning. Here are two panning ideas to try out:

How is the RF15-30mm f/4.5-6.3 IS STM’s image quality?

Beautiful image quality that leverages on the RF mount design

The RF15-30mm f/4.5-6.3 IS STM realises clear images with barely any colour bleeding or distortion across the entire zoom range. This makes it capable of sharp, high-quality images of landscapes, buildings, and other scenes that usually benefit from an ultra-wide-angle lens, all the way from the image centre to the edges.

While the RF15-30mm f/4.5-6.3 IS STM is not an L-series lens, it benefits from the large mount diameter and short back focus of the RF mount, which contributes to better image quality. It also incorporates special lens elements: one aspherical lens and two UD lenses. The aspherical lens works in combination with the in-camera digital distortion correction function* to correct the distortions that become more visible at wider angles, whereas the two UD lenses effectively correct transverse chromatic aberration, which usually manifests as discolouration, including colour fringing.

A: UD lenses
B: Aspherical lens

* When this lens is attached, the Distortion Correction function on the camera will be enabled.
When using the lens with the EOS R/RP, please ensure that the camera firmware is the latest version.
The Multiple Exposures function will be unavailable when using this lens with the EOS R/RP/Ra/R5/R6.

Is the RF15-30mm f/4.5-6.3 IS STM good for video?

Wide-angle + compact = ideal for video

The AF on the RF15-30mm f/4.5-6.3 IS STM is driven by a lead-screw type stepping motor (STM), which moves the focus smoothly and silently—perfect for video. The 15mm to 30mm focal range captures a wide area of the scene even if you don’t have much space to step back, convenient for scenes where you need to capture yourself and other objects such as products on the table, all in the same frame. Filming alone with no assistant? With the short working distance, changing settings or adjusting the camera angle is just an easy reach away. The compact size of the lens contributes to a small, light setup—great for vlogging and filming snippets of your everyday life.

How is the RF15-30mm f/4.5-6.3 IS STM different from existing RF wide-angle zoom lenses?

High on mobility

With the RF15-30mm f/4.5-6.3 IS STM, there are now three ultra-wide-angle zoom lenses in the RF lens lineup. While the focal ranges of these lenses differ slightly, the difference is not significant.

The two professional-grade L-lenses, of course, provide higher image and build quality than the RF15-30mm f/4.5-6.3 IS STM. But for users who prioritise stretching the budget over perks like weather sealing, the speed and shallow depth of field of f/2.8, or having a constant maximum aperture even when you zoom in, the RF15-30mm f/4.5-6.3 IS STM should provide sufficient image quality and versatility.

Another significant difference between the lenses is their weight: at approximately 390g, the RF15-30mm f/4.5-6.3 IS STM is the lightest. If you lead an active lifestyle and want an ultra-wide-angle zoom lens to take on hikes and walkarounds, the RF15-30mm f/4.5-6.3 IS STM is the lens that best complements the mobility and portability of the mirrorless EOS R system.
