The best Canon wide-angle zooms in 2020: lenses that give you the big picture!

The best Canon wide-angle zooms in 2020

If you want to literally broaden your horizons, the best Canon wide-angle zoom lenses can truly transform the perspectives you're able to capture with your DSLR or mirrorless camera. 

While your camera may have come with a kit lens, which provides a useful all-purpose focal range, even its widest setting won't give you the same compositional opportunities as an ultra-wide viewing angle. 

The best Canon wide-angle lenses are perfect for landscapes, enabling you to fit sweeping vistas and sprawling skies into the frame. And they're every bit as useful for working indoors, too, whether you're photographing interiors or you shoot events and weddings where you need to squeeze everything in without crushing yourself against the opposite wall. 

However, the best wide-angle lenses aren't only good for cramming more into your compositions; they can also be put to great creative effect by enabling you to exaggerate perspectives, receding the backdrop while dramatically separating a subject in the foreground. And of course, since such short focal lengths introduce a huge depth of field, you can keep the fore-, mid- and background planes simultaneously sharp in your scene.

Bear in mind that if you’re buying a wide-angle optic for an APS-C camera, it’s vital to choose an APS-C lens. While you can certainly use full frame EF lenses on EF-S DSLRs and EOS M mirrorless cameras, the 1.6x crop factor of the APS-C sensor means that the effective focal length will be increased (so, for example, a 17-40mm EF lens becomes a 27.2-64mm) so you won't get the full benefit. 

With that in mind, here are the best Canon wide-angle lenses for both APS-C and full-frame DSLRs and mirrorless cameras…

Canon EF-M

1. Canon EF-M 22mm f/2 STM

This pancake lens is a really portable option for a Canon EOS M body

Mount: Canon EF-M | Elements/groups: 7/6 | Diaphragm blades: 7 | Autofocus: Stepping motor | Stabilizer: No | Min focus distance: 0.15m | Max magnification: 0.21x | Filter thread: 43mm | Dimensions (WxL): 61x24mm | Weight: 105g

Incredibly small and light
Bargain price
Good build and fast AF performance
No image stabilization
Sharpness is good, but not great

Thanks to the 1.6x crop factor of APS-C format EOS M mirrorless camera bodies, the 22mm focal length of this lens equates to 35.2mm in full-frame terms. It gives the same 63-degree viewing angle as using a 35mm lens on a full-frame camera, which is perfect for documentary and street photography. It has a fast f/2 maximum aperture, but its thin pancake design means it is still very small and light.

Given the small size of Canon EOS M bodies, the overall camera and lens combination is particularly stealthy. The STM (Stepping Motor) autofocus system is quick and very quiet, and manual focusing benefits from an optional focus peaking display, featured in all current EOS M cameras.

Canon EF-S

Best Canon wide-angle lens: Tamron 10-24mm f/3.5-4.5 Di II VC HLD

2. Tamron 10-24mm f/3.5-4.5 Di II VC HLD

A new and improved lens with winning features for Canon APS-C DSLRs

Mount: Canon EF-S | Full-frame compatible: No | Autofocus type: High/Low Torque Drive | Stabilizer: Yes | Minimum focus distance: 0.24m | Filter thread: 77mm | Dimensions (WxL): 84 x 85mm | Weight: 440g

High-performance autofocus system
Effective optical image stabilizer
Weather seals and fluorine coating
Rather pricier than its predecessor

A major revamp of Tamron’s original 10-24mm wide-angle zoom, this edition has a new optical design with enhanced aspherical and LD (Low Dispersion) elements. It also gains a new HLD (High/Low toque-modulated Drive) autofocus system and VC (Vibration Compensation) stabilization, which were absent in the original lens. Autofocus is faster, quieter and more accurate, and offers improved handling – this is because the focus ring no longer rotates during autofocus, while there's also now full-time manual override.

Build quality is very good, with a full set of weather seals and a keep-clean fluorine coating on the front element. The lens is compatible with Tamron’s optional ‘TAP-in Console’, for applying firmware updates and fine-tuning via a USB-connected computer. Sharpness is excellent across the entire image frame, throughout the whole zoom range, which is always a challenge for ultra-wide zooms, and there’s very little barrel distortion at the shortest focal length. All in all, it’s a star performer.

Best Canon wide-angle lens: Sigma 8-16mm f/4.5-5.6 DC HSM

3. Sigma 8-16mm f/4.5-5.6 DC HSM

This is as wide as you can go for APS-C Canon DSLRs without going fisheye

Mount: Canon EF-S | Full-frame compatible: No | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.24m | Filter thread: None | Dimensions (WxL): 75 x 106mm | Weight: 555g

Extreme maximum viewing angle
Good build quality and performance
Built-in hood precludes attachment of filters
Fairly expensive

The 1.6x crop factor of Canon’s APS-C format DSLRs makes ultra-wide viewing angles rather a challenge. Compared with most competing zoom lenses, this Sigma shaves 2mm off the shortest focal length of other lenses, and gives a truly eye-popping boost to the maximum viewing angle. It’s not a weather-sealed lens, but build quality is very good. The ring-type ultrasonic system delivers fast and quiet autofocus, complete with the usual full-time mechanical override.

Four top-quality FLD (Fluorite-grade Low Dispersion) elements are featured in the optical path to enhance image quality, while Super Multi-Layer Coatings are on hand to guard against ghosting and flare, along with a built-in hood. This also protects the bulbous front element – there’s no attachment thread for filters. although at least the two-part lens cap enables you to use 72mm filters at the long end of the zoom range, without any vignetting.

Despite the extreme viewing angle at the short end of the zoom range, sharpness remains impressive into the corners of the image frame. Colour fringing and distortions are also well controlled, making this lens the ideal choice if you want to take your viewing angles to the max.

Best Canon wide-angle lens: Tokina atx-i 11-16mm f/2.8 CF

4. Tokina atx-i 11-16mm f/2.8 CF

A modest zoom range but good performance for APS-C Canon DSLRs

Mount: Canon EF-S | Full-frame compatible: No | Autofocus type: Electric motor | Stabilizer: No | Minimum focus distance: 0.3m | Filter thread: 82mm | Dimensions (WxL): 84x92mm | Weight: 555g

High-quality optical and mechanical build
Fast and constant f/2.8 aperture
Zoom range isn’t particularly generous
Push-pull focus ring can be switched accidentally

Tokina’s first ATX 11-16mm was something of a trailblazer, bringing ultra-wide viewing to APS-C format Canon DSLRs, coupled with a fast and constant f/2.8 aperture. It came with a solid construction, typical of Tokina’s high standards of build quality. The Mark II edition of the Canon-mount lens had minimal changes to the multi-coatings, but the latest ‘atx-i’ edition looks and feels rather different. The ‘i’ stands for ‘interactive’ mutual communication between photographer and lens. It certainly looks more modern but retains Tokina’s usual ‘One-touch Focus Clutch’ mechanism. This gives you the option of switching between autofocus and manual focus modes simply by clicking the focus ring forwards or backwards. It works well on the whole, but you have to be careful not to nudge the focus ring accidentally. As with the previous editions, image quality is very good in all respects, although the overall zoom range is pretty modest.

Best Canon wide-angle lens: Sigma 10-20mm f/3.5 EX DC HSM

5. Sigma 10-20mm f/3.5 EX DC HSM

Surprisingly feature-rich lens for APS-C Canon DSLRS at a bargain price

Mount: Canon EF-S | Full-frame compatible: No | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.24m | Filter thread: 82mm | Dimensions (WxL): 87 x 88mm | Weight: 520g

Constant-aperture design
Ring-type ultrasonic autofocus
Large 82mm filter thread
No weather seals

This Sigma has a constant-aperture design, although it’s a modest f/3.5. Even so, it has the same advantage for manual exposure mode shooting, in that the aperture remains fixed throughout the zoom range. Optical attractions include two ELD (Extraordinary Low Dispersion) elements and an SLD (Special Low Dispersion) element – considering the budget price, the inclusion of posh glass along with a fast and whisper-quiet ring-type ultrasonic autofocus system is a very pleasant surprise.

An upside over Sigma’s 8-16mm is that this lens has a detachable hood and a filter attachment thread. Sharpness is excellent throughout the zoom range in the central region of the frame, but drops off a little more than usual in the corners. Barrel distortion at the minimum focal length is fairly minimal, as is colour fringing throughout the zoom range. This lens has been on the market for almost a decade now, and predates Sigma’s ‘Global Vision’ lineup, but it’s unbeatable value at the price.

Best Canon wide-angle lens: Canon EF-S 10-18mm f/4.5-5.6 IS STM

6. Canon EF-S 10-18mm f/4.5-5.6 IS STM

A real lightweight for Canon APS-C DSLRs, but in a good way

Mount: Canon EF-S | Full-frame compatible: No | Autofocus type: Stepping Motor | Stabilizer: Yes | Minimum focus distance: 0.22m | Filter thread: 67mm | Dimensions (WxL): 75 x 72mm | Weight: 240g

Very compact and lightweight
Good autofocus and stabilization systems
Plastic mounting plate
Lens hood sold separately

We prefer this new Canon lens to the veteran EF-S 10-22mm, and not just because it’s only about a third of the price. The 10-18mm is wonderfully compact and lightweight for a wide-angle zoom – it’s actually less than half the weight of the competing Sigma APS-C format lenses, so ideally suited to travel photography. The weight saving is partly due to the mounting plate being made from plastic rather than metal, but the lens still feels reasonably robust.

The STM (Stepping Motor) autofocus system is fast for stills and ideal for video capture, delivering smooth focus transitions and being virtually silent in operation. Another advantage over the Canon 10-22mm is that this lens adds image stabilization, which is great for indoor or twilight shooting – and yes, camera shake can still be a problem even with ultra-wide lenses.

In our tests, this lightweight lens beat the bigger Canon 10-22mm for sharpness and control over colour fringing. It’s great value at the price, although, typically for a Canon non-L-series lens, you have to buy the hood separately.

Canon EF

Best Canon wide-angle lens: Sigma 14-24mm f/2.8 DG HSM | A

7. Sigma 14-24mm f/2.8 DG HSM | A

It’s our new favourite wide-angle zoom for full-frame Canon DSLRs

Mount: Canon EF | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.26m | Filter thread: None | Dimensions (WxL): 96 x 135mm | Weight: 1,150g

Superb build quality and performance
Virtually no distortion
Quite large and weighty
No filter attachment thread

Sigma has really gone to town with wide-angle zooms in its Global Vision lineup, but this lens is the latest and greatest. It has a slightly more modest maximum viewing angle than the 12-24mm Art lens, but a faster aperture rating; both are practically identical in size and weight. High-tech glass includes an ultra-high-precision moulded glass aspherical front element, combined with three FLD (Fluorite-grade Low Dispersion) and three SLD (Special Low Dispersion) elements.

The lens is immaculately engineered and, unlike the Sigma 12-24mm Art, it gains a full set of weather seals instead of just a sealed mount. A fluorine coating is applied to repel muck and moisture, while the built-in lens hood gives physical protection to the protruding front element, as well as helping to reduce ghosting and flare. Unusually, however, you can have this exchanged for a shorter, circular hood for minimizing shadows when using multiple cameras in video capture for creating virtual reality environments.

Sharpness and contrast are very impressive even when shooting wide-open at f/2.8, and while distortions are minimal from the Sigma 12-24mm Art, this lens is virtually distortion-free. Colour fringing is also negligible, even around high-contrast edges towards the extreme corners of the frame. It’s an absolutely stellar lens in every respect.

Best Canon wide-angle lens: Canon EF 16-35mm f/4L IS USM

8. Canon EF 16-35mm f/4L IS USM

Relatively compact stabilized lens for full frame Canon DSLRs

Mount: Canon EF | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: Yes | Minimum focus distance: 0.28m | Filter thread: 77mm | Dimensions (WxL): 83 x 113mm | Weight: 615g

Relatively lightweight and manageable
Great autofocus and stabilization performance
Maximum viewing angle is comparatively modest
Sharpness drops off in the corners of the frame

If money’s no object, the Canon EF 16-35mm f/2.8L III USM is an f/stop faster than this lens, and a darling of the most demanding pro photographers; however, it’s bigger, heavier, lacks image stabilization and costs twice the price. Meanwhile, the Canon EF 11-24mm f/4L USM has a much wider maximum viewing angle but is fiendishly expensive, making the Sigma 12-24mm Art a much better-value buy. For an own-brand Canon wide-angle zoom for full-frame cameras, this lens is our favourite.

It’s relatively compact and lightweight, has a highly effective 4-stop image stabilizer, and maintains a very high standard of build quality and performance throughout. Like most L-series lenses, it’s robust and weather-sealed, with excellent handling. Optical highlights include two UD (Ultra-low Dispersion) elements and Super Spectra coating. Fluorine coatings are also applied to the front and rear elements.

Centre-sharpness is as spectacular as from the Sigma 14-24mm, although it drops off a little more towards the extreme edges and corners of the frame. Colour fringing is controlled particularly well, and there’s fairly little barrel and pincushion distortion at the short and long ends of the zoom range respectively. It’s certainly no lightweight in terms of performance and, unlike many wide-angle zooms for full-frame DSLRs, it has a detachable lens hood and filter attachment thread.

Best Canon wide-angle lens: Sigma 12-24mm f/4 DG HSM | A

9. Sigma 12-24mm f/4 DG HSM | A

Take full frame Canon DSLR viewing angles to the extreme

Mount: Canon EF | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.24m | Filter thread: None | Dimensions (WxL): 102 x 132mm | Weight: 1,150g

Immense maximum viewing angle
Half the price of the Canon 11-24mm
Fairly big and heavy
Only the mounting plate is weather-sealed

The upgraded ‘Art’ edition of Sigma’s 12-24mm lens goes head-to-head with the Canon EF 11-24mm f/4L USM, but only costs about half the price. Unlike the previous edition it has a constant-aperture design, generally preferred by enthusiast and professional photographers. The revamped optical path incorporates an extra-large-diameter aspherical element and five premium FLD (Fluorite-grade Low Dispersion) elements. Fluorine coatings are applied to the front and rear elements, and the mounting plate is weather-sealed.

The uprated ring-type ultrasonic autofocus system is faster, and the new lens is compatible with Sigma’s optional USB Dock for applying firmware updates and fine-tuning. One downside is that the Art lens is rather bigger and heavier than the older edition. Sharpness and contrast are excellent, and sharpness doesn’t drop off too much even at the extreme corners of the frame, despite the ultra-wide maximum viewing angle. Overall, it’s the best-buy zoom on the market for full-frame DSLRs, if you want maximum viewing width.

Best Canon wide-angle lens: Tamron SP 15-30mm f/2.8 DI VC USD G2

10. Tamron SP 15-30mm f/2.8 DI VC USD G2

This G2 edition has faster AF, better stabilization and more besides

Mount: Canon EF | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: Yes | Minimum focus distance: 0.28m | Filter thread: None | Dimensions (WxL): 85 x 145mm | Weight: 1,110g

Combines a fast f/2.8 aperture with stabilization
G2 edition has significant upgrades
Rather pricier than the original edition
Typically, it has no filter thread

This Tamron gives a maximum viewing angle that’s midway between that of the Canon 16-35mm and Sigma 14-24mm. It shares the fast and constant f/2.8 aperture of the Sigma, while adding the bonus of a highly effective 4.5-stop optical stabilizer. 

The higher-performance stabilizer is one of the key upgrades in the new G2 (Generation 2) edition, along with a faster and more accurate autofocus system. Like the original lens, there’s a full set of weather seals, but the fluorine coating on the front element is improved, and the Canon-fit version of the G2 also adds a rear filter holder in its mounting plate. 

One drawback is that the Tamron is nearly twice the weight of the Canon 16-35mm, but that’s the price you pay for the faster f/2.8 aperture rating.

High-quality optics include a specially developed XGM (eXpanded Glass Molded Aspherical) element and several LD (Low Dispersion) elements, and the G2 features a newly developed coating, which is used in addition to the previous lens’s mix of nano-structure and conventional coatings.

Image quality and handling are highly impressive and, even though the G2 is a third more expensive than the original edition, it’s still good value at the price.

Canon RF

Best Canon wide-angle lens: Canon RF 15-35mm f/2.8L IS USM

11. Canon RF 15-35mm f/2.8L IS USM

A top-spec ultra-wide zoom for EOS R-series mirrorless cameras

Mount: Canon RF | Full-frame compatible: Yes | Autofocus type: Nano USM | Stabilizer: Yes | Minimum focus distance: 0.28m | Filter thread: 82mm | Dimensions (WxL): 89x127mm | Weight: 840g

Premium image quality and handling
Filter thread with detachable hood
Typically weighty for an f/2.8 zoom
Very expensive to buy

To put Canon’s RF-mount wide-angle zoom into perspective, it’s about twice the price and nearly twice the weight of Nikon’s competing 14-30mm lens for Z-series cameras. It feels less well matched to a slim-line mirrorless camera body, but the Canon lens certainly goes large on features and handling. The main reason for the higher selling price and bigger build is that it’s an f/2.8 rather than f/4 lens, so it’s an f/stop faster throughout the whole aperture range. As an L-series lens, it has tough, weather-sealed build quality of a pro-grade standard. Handling bonuses include a 5-stop optical stabilizer, a customisable control ring and a detachable hood, which enables the fitment of 82mm filters or filter holders. Image quality is gorgeous, although corner-sharpness could be a little better when shooting wide-open at the short end of the zoom range.
