Canon’s EF-mount system has been around for decades now, and there are absolutely loads of optics out there to suit the best Canon EOS DSLRs. Wide-angle zooms, high-quality super-telephotos, pin-sharp macro lenses, budget-friendly travel-zooms – you name it, the Canon EF system probably has it. We’ve put together this guide to help you find the best of the best – challenging though it was, given the range of choice!

Canon is more concerned these days with its mirrorless line-up than DSLRs (see the best Canon mirrorless cameras); but there remain plenty of reasons to choose EF-mount lenses.

For one, they are getting cheaper as more mirrorless options come out; especially second-hand. For another, EF-lenses can be adapted to work on Canon’s RF-mount mirrorless cameras, in most cases with full functionality of autofocus and stabilisation. This makes potential options of the lenses on this list, even if you’ve already switched to mirrorless and started assembling a system of Canon RF-mount lenses.

If you’re new to all this, fear not – there is an explainer section on how to choose a good Canon EF lens at the bottom of the page, where there is also an FAQ section with answers to the most common questions we receive about DSLR lenses. For more budget-friendly choices, check out our guide to the best second-hand DSLR lenses.

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

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

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

At a glance:

  • APS-C lens (equivalent focal range: 16-28.8mm)
  • Construction: 14 elements, 11 groups
  • Weight: 240g
  • Price new: $239 / £254
  • Price used: $146 / £151

Slim and lightweight, offering a wide-angle perspective, the Canon EF-S 10-18mm f/4.5-5.6 IS STM is ideal for any APS-C Canon DSLR. You might be using the beginner-friendly Canon EOS 2000D / Rebel T7 (same camera, just named differently in different territories) or the enthusiast-focused Canon EOS 90D – either way, you have a lens that will balance well and deliver all the features you might need. Autofocus is nice and speedy, and also very quiet, which is useful for video work. There’s also a four-stop image stabilisation system on board.

Its affordable price tag makes this lens a bargain for any crop-sensor Canon DSLR user – but there are compromises. For instance, the lens body is constructed from plastic rather than metal, making it rather more fragile than premium lenses. Also, while the maximum aperture of the lens is f/4.5, it can actually only shoot at f/4.5 when locked at its widest setting of 10mm (16mm equivalent); the maximum aperture drops very sharply to f/5 once you start zooming.

Still, for an affordable, portable lens for architecture photography, the Canon EF-S 10-18mm f/4.5-5.6 IS STM is a prime choice.

Pros:

  • Near-silent focusing
  • Four-stop stabilisation
  • Small size

Cons:

  • Plasticky build
  • Electronic manual focus

Best Canon lens for macro: Canon EF 100mm f/2.8L Macro IS USM

Canon EF 100mm f2.8L Macro IS USM lens

Canon EF 100mm f2.8L Macro IS USM

At a glance:

  • Full-frame lens

  • Price new: $ 1,299 / £ 1,239
  • Price used: $615 / £564

Planning on getting into macro photography? Shooting frame-filling close-ups of minuscule subjects is one of the most technically demanding photographic disciplines out there – and one of the most rewarding. Having the right lens is crucial for macro photography; and the Canon EF 100mm f2.8L Macro IS USM is most certainly that.

For starters, it’s one of Canon’s ‘L’ lenses. The company reserves this designation for its top-of-the-line lenses, built to exacting quality standards inside and out. Next, it’s a ‘true’ macro lens – that’s to say, it has a reproduction ratio of 1:1, i.e. the size of the subject as rendered on your sensor plane is the same as its actual real-life size.

You can show the tiniest things in glorious, close-up detail. You’ll be up close and personal to these subjects, which is why the EF 100mm f2.8L Macro IS USM’s 30cm minimum focusing distance and telephoto focal length come in handy.

Like many macro lenses, the EF 100mm f2.8L Macro IS USM doubles up well as a portrait lens, helped by its maximum aperture of f/2.8. This is where you might get more use out of one of its additional features – image stabilisation, which tends to be of limited use in macro photography where tripods are near-standard. If you’re on the hunt for a dedicated portrait lens, our guide to the best lenses for portrait photography may help.

Pros:

  • Superb detail resolution
  • Fast AF and smooth MF
  • High-quality build

Cons:

  • Price jump over previous iteration

Best second-hand Canon lens: Canon EF 17-35mm f/2.8L USM

Canon EF 17-35mm f/2.8L USM lens

Canon EF 17-35mm f/2.8L USM

At a glance:

  • Full-frame lens
  • Construction: 15 elements, 10 groups
  • Weight: 545g
  • Price used: $499 / £389

An older L-series lens, the Canon EF 17-35mm f/2.8L USM has been discontinued, but remains on the second-hand market at hugely reduced prices. Many similar EF lenses have arrived since, such as the Canon EF 16-35mm f/2.8L III USM and the cheaper Canon EF 16-35mm f/4L IS USM. However, the good old EF 17-35mm f/2.8L USM still holds a place in plenty of photographers’ hearts.

A hardy, rugged jack-of-all-trades, the Canon EF 17-35mm f/2.8L USM is built to last. The relatively wide focal range makes it useful for documentary and street photography. Indeed, until sharper successors came along it was a favourite among the press pack.

Nowadays it’s probably not quite sharp enough to meet the demands of digital newsrooms and press agencies, but for the enthusiast photographer, it’ll deliver solid images and withstand any conditions you care to throw at it. The constant f/2.8 aperture also makes it useful in broad-ranging light conditions.

Weighing 545g, it balances pretty nicely on Canon DSLRs without making any of them too front-heavy. At current second-hand prices, the Canon EF 17-35mm f/2.8L USM is a terrific lens to pick up. It’ll work brilliantly well for travel and street photography.

Pros:

  • Lightweight and well balanced
  • Can take some serious punishment
  • Solid image quality and f/2.8 aperture
  • Excellent value for money

Cons:

  • Not as sharp as newer lenses

Best Canon lens for wildlife: Canon EF 100-400mm f/4.5-5.6L IS II USM

Canon EF 100-400mm f/4.5-5.6L IS II USM lens

Canon EF 100-400mm f/4.5-5.6L IS II USM

At a glance:

  • Full-frame lens
  • Construction: 21 elements, 16 groups
  • Weight: 1640g
  • Price new: $2,399 / £ 2,599
  • Price used: $1,486 / £1,169

One of the most common questions we get regarding the Canon lens range is, which one is best for wildlife? The absolute best would be a telephoto prime in the ‘L’ series, such as the Canon EF 800mm f5.6 L IS USM. However, that lens retails at £13,549 and as such is for high-end professionals only. For most people, the Canon EF 100-400mm f/4.5-5.6L IS II USM is going to deliver exceptional results for wildlife photography.

We tested this lens out by taking it for a challenging day photographing birds of prey in flight. Bird-in-flight images (often shortened to ‘BIF’) are of great interest to wildlife photographers, and the Canon EF 100-400mm f/4.5-5.6L IS II USM does a commendable job of nailing the shot, time and again.

Its image quality is top-notch too – when we took our bird images back to the computer for inspection, we were hugely impressed with the sharpness on display. The image stabiliser functionality was also really helpful for getting those tricky wildlife shots. The ‘L’ tag on the body means that the construction is rock-solid, too.

The only drawback with this lens is its price, which may be too much for some users. If you want something cheaper for wildlife photography, try the Sigma 70-200mm F2.8 DG OS HSM Sports or the Tamron 100-400mm f/4.5-6.3 Di VC USD, both of which are featured further down this list.

Pros:

  • Superb autofocus capabilities
  • Effective stabiliser
  • Exceptional image quality

Cons:

  • Intimidating price
  • Some vignetting at wide apertures.

Best Canon EF street lens: Canon EF 35mm f/1.4L II USM

Canon EF 35mm f/1.4L II USM lens

Canon EF 35mm f/1.4L II USM

At a glance:

  • Full-frame lens
  • Construction: 14 elements, 11 groups
  • Weight: 760g
  • Price new: $ 1,999 / £2,199
  • Price used: from $1,558 / £1,099

Canon went back to the drawing board when it came to update its popular wide-aperture wide-angle prime: the Canon EF 35mm f/1.4L. Competition had been increasing thanks to Sigma’s introduction of its Sigma 35mm f/1.4 Art lens, a much cheaper alternative that still delivered the goods optically. Canon needed to pull something out of the bag to keep up.

The one thing it did not do, perhaps inevitably, was cut the price. While Sigma Art f/1.4 lenses tended to be around the £700-800 mark, the Canon EF 35mm f/1.4L II USM arrived on the scene an eye-watering £1,799. It’s currently retailing new for around £2,199. Inflation, baby. Isn’t it great?

But the thing is, the Canon EF 35mm f/1.4L II USM is a beautiful, razor-sharp lens that really does justify its price tag. Earning all five stars in our full review, the lens is super sharp at the edges and centre of images, and it is highly effective at controlling chromatic aberration thanks to its new BR (Blue Spectrum Refractive) optic. It’s heavy – but not too heavy to handle.

As we said at the time, if you want the best, you do have to pay for it. For wedding photographers, events photographers and other professionals, we’d say this lens is well worth the investment.

Pros:

  • Superb image quality
  • Smooth bokeh from 9-blade aperture
  • Good all-purpose focal length

Cons:

  • High asking price
  • Heavy for a 35mm

Best cheap Canon lens: Canon EF 50mm f/1.8 STM

Canon EF 50mm f/1.8 STM

Canon EF 50mm f/1.8 STM

At a glance:

  • Full-frame lens
  • Construction: 6 elements, 5 groups
  • Weight: 162g
  • Price new: $124 / £114
  • Price used: $99 / £79

This small ‘nifty fifty’ improves upon Canon’s older designs and has been brought up to date by incorporating a Stepper Motor (STM) for smoother and quieter AF. Compatible with full-frame and APS-C DSLRs, it becomes a highly practical and creative short telephoto lens that’s equivalent to 80mm when attached to the latter.

If you enjoy shooting portraits – or any subject where you’d like to create attractive background blur – this lens allows you to do it, without breaking the bank. It has a smaller 49mm filter thread and improved build quality over Canon’s older EF 50mm f/1.8 II, but produces results of similar quality. Stopping down from f/1.8 to f/2.8 improves sharpness and all trace of corner shading disappears by f/4. It’s one of the most popular lenses for those who feel they’ve outgrown a kit zoom.

Pros:

  • Super-light
  • Very cheap
  • Good for full-frame and APS-C

Cons:

  • Inevitably sharpness compromise at this price
  • Autofocus not silent

Best Canon lens for portraits: Canon EF 85mm f/1.4L IS USM

Canon EF 85mm f/1.4L IS USM lens

Canon EF 85mm f/1.4L IS USM

At a glance:

  • Full-frame lens
  • Construction: 14 elements, 10 groups
  • Weight: 950g
  • Price new: $1,599 / £ 1,719
  • Price used: from $ 1,358 / £1,199

This new L-series telephoto prime will have great appeal to portrait and wedding photographers who desire superior image quality to the ageing EF 85mm f/1.8 USM. It will also be of interest if you don’t want to splash out £1,765 for the larger and heavier EF 85mm f/1.2L II USM.

The big attraction is its optical image stabilisation, which is effective to four stops and will be a godsend for wedding photographers in low-light venues such as churches and dimly lit reception interiors. It has a 77mm filter thread, 0.85m minimum focusing distance and weather sealing that’ll provide reassurance when used in variable weather conditions.

Pros:

  • Superb image quality
  • Four-stop stabilisation
  • Weather sealing

Cons:

  • Expensive
  • Heavy

Best Canon lens for zoom: Canon EF 70-300mm f/4-5.6 IS II USM

Canon EF 70-300mm f/4-5.6 IS II USM lens

Canon EF 70-300mm f/4-5.6 IS II USM

  • Full-frame lens
  • Construction: 17 elements, 12 groups
  • Weight: 710g
  • Price new: $599 /£579
  • Price: from $489 / £399

This mid-range telephoto zoom incorporates four-stop image stabilisation and a new, Nano USM motor for fast and silent autofocus. It weighs 720g, has a nine-bladed diaphragm and is equivalent to 112-480mm on an APS-C DSLR.

An interesting idea is the lens’s LCD panel, which can be used to cycle through three modes: focal length, a camera shake meter, and the current focus distance complete with depth-of-field scale. It’s a great match to mid-range DSLRs, offering a great balance between portability and image quality.

Pros:

  • Fast, silent AF
  • Useful LCD readout panel
  • Balances well with mid-range DSLRs

Cons:

  • No weather seal around mount
  • £75 extra for a hood is inexcusable

Best Canon pancake lens: Canon EF-S 24mm f/2.8 STM

Canon EF-S 24mm f/2.8 STM lens

Canon EF-S 24mm f/2.8 STM

At a glance:

  • APS-C lens (equivalent focal length: 38mm)
  • Construction: 6 elements, 5 groups
  • Weight: 125g
  • Price new: $149 / £149
  • Price used: $102 / £92

This ultra-slim pancake prime is one of the least expensive lenses on the market. Measuring just 22.8mm thick, it can easily be carried around all day without inconvenience. It’s a marvellous little optic for travel and street photography, providing a 38mm equivalent angle of view on the Canon APS-C DSLRs, for which it is made.

The lens does exhibit vignetting at wide apertures, as well as distortion – but both are easily remedied in software. Most importantly, the lens focuses accurately and gives consistently sharp, detailed images. With its bargain price, carry-everywhere size and highly competent imaging performance, this lens deserves to be high on the wish list of many a Canon APS-C DSLR user.

Pros:

  • Ultra-slim
  • Useful 38mm equivalent focal length
  • Good sharpness

Cons:

  • Some vignetting
  • Some distortion (both easily corrected though)

Best Canon walk-around lens: Canon EF 24-105mm f/4L IS II USM

  • Construction: 17 elements, 12 groups
  • Weight: 795g
  • Price new: $1,299 / £1,319
  • Price used: from $882 / £ 614

This lens is the replacement for one of Canon’s best-selling full-frame optics for more than 10 years – the EF 24-105mm f/4L USM. It features a revised optical design that has made it a little sharper towards the edges with less barrel distortion at the wide end.

Vignetting isn’t quite as severe either and it features a new electronic aperture diaphragm system (EDM) that provides smoother and quieter aperture changes during movie capture. It’s the best 24-105mm full-frame zoom Canon makes, but isn’t quite as razor sharp as the stunning EF 24-70mm f/2.8L II USM.

Pros:

  • Do-everything zoom range
  • Excellent sharpness
  • Well optimised for video

Cons:

  • Quality lags behind the flagship lenses
  • Quite pricey for an f/4

Canon and its engineers deserve praise for constructing one of their finest L-series lenses. The Canon EF 11-24mm f/4L USM lens is one of, if not the best, rectilinear wide-angle zooms ever made.

Full-frame users who specialise in landscape, architecture, or interior photography will want this. A lens that can squeeze more surroundings into the frame, and do so at exceptional optical performance like this, is one for the wish list.

You may find it second-hand. A used model in good condition will cost around $1,800/ £1,500.

Pros:

  • Outstanding image quality
  • Premium construction
  • Full-time manual focus override

Cons:

  • Prohibitive price

  • Construction: 16 elements, 12 groups
  • Weight: 615g
  • Price new: $1,299 /£1,389
  • Price used: $679 / £429

This ultra-wide-angle zoom lens is ideal for landscape, architecture, and interior shots where you need to get as much as possible into the frame. The built-in image stabilisation (IS) will help when slower shutter speeds are needed, such as shooting in low-light conditions.

With an f/4 aperture, this lens is best suited to landscapes and detailed images, and the best results are found when shooting at f8. We were impressed by the image quality produced by the lens in our review. As a Canon L series lens, it is fully weather-sealed so should endure adverse conditions.

Pros:

  • Solid image quality
  • Weather sealing
  • Built-in stabilisation

Cons:

  • Not cheap
  • Only f/4

Sigma produce some impressive and interesting lenses, as well as offering similar alternatives to Canon’s own brand offerings. This 70-200mm f2.8 lens contains optical image stabilisation, with 4-stops of stabilisation. It delivers impressively sharp results, with low levels of distortion.

As well as weather-sealed, it also benefits from being noticeably cheaper than Canon’s 70-200mm f2.8 lens, saving some serious money!

Pros:

  • Excellent sharpness
  • Powerful 4-stop stabilisation
  • Undercuts Canon’s own lens on price

Cons:

  • Very heavy

  • Price used: from $638 / £609

Tamron has been on something of a discontinuation spree with its DSLR lenses lately, but there are still some excellent ones from this manufacturer for Canon EF mount. Case in point: the Tamron 100-400mm f/4.5-6.3 Di VC USD.

A relatively cheap lens that punches above its weight, this optic arrived a few months after Sigma’s own Contemporary version, at a price designed to undercut it. If you want a Canon own-brand 100-400mm lens, your only options are the hugely expensive ones like the L lens listed earlier in our guide. So this Tamron optic fills a good niche.

It’s a great performer for the price, too. Sharpness is great at all focal lengths, especially in the centre of the frame, and the USD (Ultra-sonic Silent Drive) autofocus system delivers the goods. The Canon L lens is built to last a lifetime, and is generally better in all categories, but it’s also almost four times the price. Tamron’s 100-400mm f/4.5-6.3 Di VC USD lens offers tremendous value for money.

Pros:

Excellent value

Reliable autofocus

Very good centre sharpness

Cons:

  • Some softness in corners
  • Plasticky build

Another alternative to Canon’s own brand lens, the 24-70mm f2.8 DG OS HSM Art lens offers the a bright f2.8 aperture throughout the zoom range. It has the benefit of optical image stabilisation, which is missing from Canon’s more expensive 24-70mm f2.8L II USM lens, at £2109. It’s also a compact lens, so a good choice for those looking for something smaller.

Pros:

  • Optical image stabilisation
  • Relatively portable
  • Constant f/2.8 aperture

Cons:

  • No weather sealing

The Sigma 40mm F1.4 DG HSM Art lens is designed for optimum image quality, with minimal distortion. Slightly wider than the typical 50mm lens,  the Sigma 40mm F1.4 is a great choice for a bright prime lensfor those looking for something different. It offers exceptional image quality and beautiful background blur (bokeh). However, it is large and weighty at 1.2kg.

Pros:

  • Bright aperture
  • Interesting focal length
  • Gorgeous bokeh

Cons:

  • Bulky
  • Weighs more than a kilo

How to choose a Canon EF / EF-S lens

Here are the key criteria to consider when selecting the right lens for your Canon DSLR…

Focal length / range – This is the first decision to take when buying a lens, and it will likely be dictated by what subjects you want to shoot. Those capturing architecture and landscape photography will likely opt for a wide-angle, in order to get as much of their expansive subjects in the frame as possible. For action, wildlife and animal photography, a telephoto is your best bet; being limited in how close you can get to your subject. For general-purpose or documentary photographers, a good standard zoom lens will fit the bill; see our guide to the best EF-mount zoom lenses for suggestions.

Maximum aperture

The maximum aperture width of a lens affects the light it can let in, and how shallow a depth of field – delineation between subject and background – it can provide. For shooting portraits you want a large-aperture lens (at least f/2, ideally f/1.4) for that portrait ‘look’ of a sharp subject and artfully blurred background.

Sharpness – Quite a simple prospect here – how sharply does a lens render an image? Does detail extend right to the edges and corners of images? How consistent is it throughout the aperture range, or zoom range if there is one? The one way to know all this is by testing them, and we have done. Click through to our reviews throughout the guide for sample images and resolution test results.

Optical Image Stabilisation – Newer Canon EF lenses will come equipped with image stabilisation (look for the acronym ‘IS‘ in the lens name, meaning ‘Image Stabilizer‘). This system compensates for unintentional camera movement, making it possible to use slower shutter speeds or greater zoom lengths with the camera hand-held.

Autofocus system – Canon employs a variety of speedy and accurate autofocus systems on its lenses, including the Stepping Motor (STM) and the more sophisticated Ultra Sonic Motor (USM). Better autofocus means you’ll stand a better chance of capturing sharp images of fast-moving subjects; but, of course, they come at a price. If you’re planning on shooting video, you may also want to check whether a lens has a silent AF system.

Macro capabilities – For shooting close-ups and macro photography, look for a lens with “Macro” in the name, as this will allow you to get closer to your subject. This means a lens that can reproduce a subject at life-size – or close to – on the sensor, meaning you can fill the frame with the tiniest of things.

Canon EF lenses: Frequently asked questions

FAQ: Which Canon EF lenses have image stabilisation?

Image stabilisation is a popular feature on modern digital cameras and lenses. It improves sharpness by compensating for unintentional camera movement from hand-held use (without a tripod). A good optical stabilisation system allows the capture of sharper images at slower shutter speeds. As a slower shutter speed allows more light to the sensor, photographers may produce a usable image in light that would otherwise be too low.

Some Canon EF lenses have built-in stabilisation, others do not. Check the name. The initials ‘IS’ denotes image stabilisation. The Canon EF 16-35mm f/4L IS USM is, therefore, a stabilised lens.

Be aware that other lens manufacturers use different terms and acronyms for stabilisation. Third-party lenses will be different. Tamron, for instance, uses ‘Vibration Compensation’, which is shortened to ‘VC’. This is how you know the Tamron 100-400mm f/4.5-6.3 Di VC USD has built-in stabilisation. Know who you’re dealing with!

Canon DSLRs do not have 5-axis optical stabilisation as its mirrorless cameras do; so picking up a lens with the feature can provide a real shooting advantage.

FAQ: Can you use Canon EF lenses on mirrorless cameras?

Yes, you can use Canon EF lenses on Canon mirrorless cameras –  as long as you have the right adapter. These are specific to each of the Canon RF mirrorless cameras and Canon EOS M models, so be sure to source the right one. They are quite plainly labelled the Canon Mount Adapter EF-EOS R ($99 / £119) and the Canon EF-EOS M Mount Adapter ($179 / £139).

With an adapter in place (slotted between camera and lens), the EF lens should work seamlessly on your mirrorless camera body – nothing of the functionality of autofocus and optical stabilisation features is lost. It’s especially good news for photographers who have accrued an EF-mount lens collection that they can use for switching to mirrorless… [if, indeed, they do! The question of DSLR vs mirrorless: which is better isn’t as clear-cut as you might think].

It’s also possible to adapt Canon EF lenses to other mirrorless systems using third-party adapters.  Urth and Metabones offer a range of adapters that allow you to pair Canon EF lenses with other mounts like Sony E, Fujifilm X and Micro Four Thirds.

This can be a boon when switching from one system to another. BUT the reliability of electronic functions such as autofocus and stabilisation may be compromised – or, indeed, may not work at all.

Be aware, for instance, you can use an Urth adapter to mount an EF or EF-S lens to a Micro Four Thirds body. The adapter is completely manual, so there is no communication between the camera and the lens. This means manual focus only – and if your lens doesn’t have an on-body aperture ring, you’ll have no way to adjust the aperture.

Urth and Metabones do offer electronic adapters for certain systems, though these tend to be expensive. Search on Amazon and you’ll also find plenty of cheap adapter options from manufacturers you’ve never heard of – there’s an obvious gamble on quality with some of these.

FAQ: What’s the difference between Canon EF lenses and EF-S?

Canon EF lenses come in two varieties, EF and EF-S. Which ones you can use will depend on the size of the sensor inside your Canon DSLR – whether it’s full-frame or a smaller APS-C chip. Pro and advanced enthusiast DSLRs like the Canon EOS 5D Mark IV are generally full-frame. Smaller, cheaper DSLRs like the EOS 250D usually field an APS-C sensor. All cameras’ sensor sizes are readily available online, and easily searched.

The key points to remember are as follows:

Canon EF lenses can be used on both full-frame and APS-C cameras. The majority of Canon DSLR lenses fall into this category. They will fit any Canon DSLR, though when fitted to an APS-C camera, the smaller sensor size will incur what’s called a crop factor, extending the effective focal length of the lens. Canon has a crop factor of 1.6x: so a 50mm lens mounted on a Canon APS-C DSLR will produce an equivalent focal length of 80mm.

Canon EF-S lenses are designed for APS-C cameras only. A Canon EF-S lens cannot be mounted on a full-frame body. They tend to be lighter than EF lenses, and balance better with smaller APS-C cameras. Also, although designed for crop sensor cameras, the crop factor still applies. This means a lens like the EF-S 10-18 f/4.5-5.6 IS STM actually produces a focal range of 16-28.8mm.

FAQ: Is Canon still making EF lenses?

Yes – for the time being, new Canon EF lenses are still rolling off the production line, and DSLR photographers can kit themselves out with brand new lenses. To find out which Canon EF lenses have been discontinued, head to our 30 Canon DSLR lenses discontinued article.

However, what Canon is not doing is developing new EF lenses. The firm is quite clearly devoting all of its R&D budget to its line-up of mirrorless lenses (see our run-down of the best Canon RF-mount lenses), and so the range of EF lenses is only likely to shrink in years to come as models are discontinued and not replaced.
