Perfect for portraiture, the best Canon portrait lenses will help take your people pictures to the next level.
While there's nothing wrong with the image quality of most standard zoom lenses, they do have their limitations. Many standard kit zooms have a variable maximum aperture that shrinks to f/5.6 at the long end of the zoom range. This translates to a fairly large depth of field, making it difficult to blur the background.
‘Fast’ (wide aperture) prime lenses typically offer a maximum aperture of f/1.4 to f/1.8, so you can really make the subject stand out by reducing the background to a dreamy blur.

Another drawback of standard zooms is that they tend to produce distortions, which switch from barrel to pincushion as you sweep through the zoom range. A prime lens is likely to be much better behaved in this respect, as it’s designed to work at a single focal length. But which focal length is best?
Traditionally, portrait photographers usually prefer to use a lens with focal length of around 85mm. This enables them to fill the image frame for head-and-shoulders or half-length portraits, without needing to get too close to the subject and invading their personal space. This distance is, however, still close enough to engage with the subject and give directions.
If you’re shooting with an APS-C-format Canon camera, a 50mm lens is a better fit for most portraiture, as the 1.6x crop factor gives an effective 80mm focal length.
Let’s compare the best Canon portrait lenses on the market, split up by the four different mounts found on current Canon EOS cameras…
Best Canon portrait lenses in 2021
Canon’s EF 85mm f/1.2L USM II lens is often seen as the holy grail of portrait primes, with its super-fast aperture rating, but we actually prefer this f/1.4 lens. It’s smaller, lighter, has a much faster autofocus system and adds weather-seals. Even more importantly, it adds a 4-stop image stabilizer which can be a massive help in getting consistently sharp handheld images under dull ambient lighting. These upgrades stack up particularly well for wedding portraiture. Another bonus of this lens over the bigger f/1.2 is that it has nine diaphragm blades rather than eight, enabling a better-rounded aperture when stopping down a little. This avoids the problem of the f/1.2 lens producing noticeably octagonal bokeh discs from defocused pinpricks of light and bright spots.
A supersized 85mm optic, this Sigma is a bit like the Incredible Hulk of portrait lenses. At 95x126mm and 1130g, it’s by far the biggest and heaviest lens in the entire test group.
Uncommonly for a Sigma lens, everything’s wrapped up in a weather-resistant dust/splash-proof casing and, as with the 50mm Art lens also on test, it’s compatible with Sigma’s USB Dock for applying firmware updates and customising settings. Also like the Sigma 50mm lens, this one comes complete with a lens hood and padded soft case.
Autofocus is fast, extremely quiet and unerringly accurate. Sharpness away from the centre of the image frame is outstanding, even when shooting wide open at f/1.4, although centre sharpness at the widest aperture isn’t quite as spectacular as from Sigma’s smaller 50mm Art lens.
All in all, this lens delivers a superb performance, but it’s pricey and rather cumbersome for an 85mm prime lens.
With an f/1.4 and 85mm maximum aperture this is a particularly good choice for full-frame DSLR users – and unlike most other primes offers image stabilization for steadier handheld shots.
Like its 45mm sibling below, this optic is compatible with Tamron’s TAP-in console. This enables connection of the lens to a computer via a USB link for updating firmware and customising settings, such as fine-tuning autofocus.
Physically smaller and lighter in weight than the competing Sigma 85mm f/1.4 DG HSM A, this optic is nevertheless larger and weightier than its EF 85mm f/1.8 USM rival (below) that shares the same maximum aperture.
At 700g, it’s still entirely manageable and feels well-balanced on full-frame bodies, while the VC (Vibration Compensation) system is a bonus for low lighting levels.
As with the Sigma lenses below, the two Tamron's on test are also supplied with hoods to block extraneous light. Internal focusing, meanwhile, powered by ring-type ultrasonic systems, results in the front elements remaining fixed throughout the focusing range.
At f/1.8, the Tamron is more than sharp enough for portraiture and the level of sharpness is consistent across the whole frame. Bokeh is wonderfully smooth, even more so than with the Tamron SP 45mm f/1.8 Di VC USD, helped by the longer focal length.
There’s a lot to love for this lens for portraiture with a full-frame camera like the EOS 6D Mark II and EOS 5D Mark IV. Furthermore, as one of Canon’s ‘recommended’ lenses, it is sufficiently sharp for use with the ultra-high-resolution EOS 5DS and 5DS R bodies.
Like the company's EF 50mm f/1.4 USM, this one has a fairly well-rounded aperture based on eight diaphragm blades. It beats that lens by having a ring-type, rather than motor-based, ultrasonic autofocus system, which is both fast and very quiet.
Sharpness isn’t spectacular at f/1.8 but, for portraiture, it’s easily good enough to capture individual hairs and skin pores, along with excellent detail in the eyes. Border sharpness, however, is generally unnecessary in portraiture, where you’re normally more concerned with defocused softness or bokeh, which it does very well.
Overall, a top value choice for full-frame shooters.
Certainly no heavyweight, Canon’s latest 50mm f/1.8 is only 30g heavier, 1mm wider and 16mm longer than the 40mm pancake lens on test. That’s pretty impressive, considering its longer focal length and faster f/1.8 aperture rating.
At 49mm, the filter attachment thread is even smaller, but this time the front element is quite deeply recessed, which makes the ES-68 lens hood a genuinely optional accessory.
As well as its more advanced autofocus system, other upgrades over the previous EF 50mm f/1.8 lenses include a metal rather than plastic mounting plate, and seven diaphragm blades rather than five, which give a more well-rounded aperture. This is particularly useful for avoiding the obvious pentagonal shapes of defocused bright objects when stopping down a little, which plagued images taken with the earlier 50mm lenses.
Performance in terms of colour fringing is about equal to the previous version, and there’s marginally less barrel distortion. Overall, at this price, the 50mm f/1.8 STM is a steal.

You certainly can’t accuse Sigma’s 50mm Art-line lens of being a lightweight contender, being physically twice as long and nearly three times heavier than the Canon EF 50mm f/1.4 USM.
The reason for the upsizing and weight gain is that the Sigma has a much more complex design than the EF 50mm f/1.4 USM, with 13 optical glass elements and a well-rounded aperture, thanks to its nine diaphragm blades.
Another Sigma upgrade is that it features a fast and whisper-quiet, ring-type ultrasonic autofocus system, whereas the EF 50mm f/1.4 USM only has a motor-driven ultrasonic arrangement.
At its widest aperture, this optic has better centre sharpness than any other lens in this group, along with superb contrast. Corner sharpness is comparatively disappointing, although it picks up well if you close down the aperture by a stop or two. Colour fringing is also very well contained and distortion is practically nonexistent.
Put simply, all-round performance is exceptional.
One feature shared by all the most recent Tamron prime lenses, but lacking in the Canon and Sigma lenses on test, is optical stabilization.
When shooting portraits indoors under ambient lighting, even an aperture of f/1.4 or f/1.8 can require slow shutter speeds, unless you boost your ISO setting, which can degrade image quality. Tamron’s VC (Vibration Compensation) technology is highly effective, enabling shutter speeds of up to four stops slower before camera shake becomes a problem.
Impressive build quality is matched by strong performance from the ring-type ultrasonic autofocus system and, more importantly, excellent image quality. Sharpness and contrast are impressive, even wide open at f/1.8, while bokeh is beautiful, giving a soft and creamy appearance to defocused areas. The lens isn’t completely free distortion like the Sigma 50mm f/1.4 DG HSM A, but there’s noticeably less barrel distortion than from either of the two Canon 50mm lenses on test.
Canon’s RF 85mm f/1.2L USM is arguably the best portrait lens in the world right now. It combines premium aspherical and UD (Ultra-low Dispersion) and BR (Blue spectrum Refractive) optical elements with high-tech ASC (Air Sphere Coating) to deliver absolutely stunning image quality in all respects. Unlike the EF 85mm f/1.2 lens for DSLRs, this RF-mount lens for EOS R-series cameras features weather-seals and fluorine coatings on the front and rear elements. It also has a much faster autofocus system, although the electronically coupled manual focus ring is retained, which enables very fine and precise adjustments. Sharpness is stunning and bokeh is sublime. For the most demanding portrait photographers, there’s an even pricier ‘DS’ version of the lens, which has an additional ‘Defocus Smoothing’ coating. This further softens the edges of bokeh discs caused by defocused lights and bright spots.
There's not getting away from the fact that Canon's RF 85mm f/1.2L USM is an expensive lens. If you're an EOS R-series shooter and are looking for a more affordable portrait lens, then the RF 85mm f/2 Macro IS STM is a great choice. While it at first glance might be seen more as a macro lens with a reproduction ratio of 1:2, the 85mm focal length naturally lends itself to capturing portraits. While the maximum aperture of f/2 might not be the fastest, this lens is still capable of delivering really pleasing defocused backgrounds, while it's also incredibly sharp. If your budget won't stretch to the 85mm f/1.2, you certainly won't be disappointed with this lens.
This Samyang lens is designed for Canon’s latest, high-tech mirrorless full-frame cameras yet features no built-in electronics whatsoever. The upshot is that it’s not just a manual-focus lens. You also have to set the aperture manually using the onboard aperture ring, and there’s no lens-based EXIF data recorded with images. On the plus side, ‘focus peaking’ is available during manual focus, which makes pinpoint accuracy less hit and miss than when using manual lenses on a DSLRs. Quality optics include a hybrid aspherical element and Samyang’s Ultra Multi Coating. Image quality is very good with minimal colour fringing, distortion, ghosting or flare. Bokeh is very pleasing and sharpness is excellent at most apertures, but it drops off noticeably at f/1.4.
Portrait lenses with a telephoto focal length and f/1.4 aperture tend to be big and heavy. By stark contrast, this Sigma prime is blissfully compact and tips the scales at just 280g. It’s supremely well balanced on lightweight EOS M bodies, on which it has a very portrait-friendly 90mm ‘effective’ focal length. Although small and light, it’s well built with a metal mounting plate and Sigma’s usual ‘Thermally Stable Composite’ material. The high-quality optical path includes two aspherical elements, one of which is made from SLD (Special Low Dispersion) glass. Autofocus is fast and very accurate, based on a stepping motor, along with an electronically coupled manual focus ring. The net result is a compact lens that combines excellent sharpness with beautifully smooth bokeh, ideal for portraiture.
