The best 50mm lenses are an essential addition to the camera bag of any serious photographer. These lenses, also referred to as 'standard' lenses or 'nifty fifties', capture a perspective that's roughly equivalent to the field of the view the human eye can see, making them an ideal choice for capturing imagery with a naturalistic feel.
These lenses also run the gamut in terms of price – it's possible to spend a four-figure sum on some of the best 50mm lenses out there, but there are also some ultra-budget optics at there that offer surprisingly good quality for a minimal outlay. Of course, spending more will mean you get better features – a wider maximum aperture up to f/1.4, or even f/1.2, for instance. Cheap lenses tend to top out at f/1.8, which is still pretty useful in low light, and they have their own advantages too, as their simpler optical builds make them lighter and more portable.
There's a lot of choice out there, that's for sure. That's why we've put together this extensive guide of 50mm lenses for all the major mounts that are out there right now, as well as some that are available for multiple systems. We've split the guide into sections to make it easier to navigate, so you can easily find your system of choice.
Best 50mm lens: Equivalent focal lengths
Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.
One thing that's worth being aware of is that a 50mm lens does not always produce the field of view of a 50mm lens, depending on the sensor size of the camera you're using. On an APS-C body, such as a Fujifilm X camera, the same lens will have an effective focal length of 75mm (80mm for Canon), making it a better fit for portraiture.
Shrink down to a Micro Four Thirds camera, and a 50mm lens will have an 100mm effective focal length, more suitable for really tight portraits and short telephoto shooting.
With that in mind, the MFT lens we've included here is a bit less than 50mm: its 42.5mm focal length equates to 85mm in full-frame terms. Many regard that as spot-on for portraiture.
Whichever camp you’re in, a ‘nifty fifty’ might well be the only prime lens you ever buy, so it pays to get a good one. Even so, nobody likes spending over the odds. So let's take a look at the best 50mm lenses available right now...
The best 50mm lens in 2023
Canon EF & RF 50mm lenses
Sure, it's too big for the cameras it's made for. Sure, it costs about the same as a new EOS R camera. All these are valid points. But... well, if you use the RF 50mm f/1.2L USM, you'll understand. It is quite simply a beautiful lens that radically redefines what the L series is capable of. Real-world results are near-flawless, with exceptional sharpness even wide open at f/1.2, and the customisable control ring allows you to really make the lens your own and have it handle exactly the way you want it to. There's weather-sealing too, and a super-speedy autofocus system: in short, everything you could want from a lens of this type. It's an incredible feat of engineering by Canon.
While the RF 50mm f/1.2L USM is a stunning lens, its price means it's out of reach for many EOS R series users. That's where the new RF 50mm f/1.8 STM comes in - a cheap, compact and capable standard prime lens. The great news too is that image quality hasn't been compromised - our tests show that it's on par in some areas with the much pricier f/1.2 variant, while the build quality is noticeably better than the EF equivalent (though it's worth bearing in mind it's not weather sealed). Focusing is also very good, with the stepping motor (STM) used offering quick and quiet focus, which is fast enough to stills and smooth enough for video. The Canon RF 50mm f/1.8 STM is a fantastic everyday lens that pairs well with any RF body.
Canon’s 25-year-old 50mm f/1.4 lens might seem the obvious choice, but we prefer this newer option. It’s two-thirds of an f/stop slower, but is less than a third of the price, is much lighter and has better performance.
Unlike previous f/1.8 editions, the ‘STM’ model has a stepping motor autofocus system that gives speedy yet quiet operation. The focus ring no longer rotates during autofocus, which improves handling, as well as enabling manual override in Single AF mode.
The lens has a metal rather than plastic mounting plate, and a better-rounded aperture based on seven diaphragm blades instead of just five.
After testing multiple samples of the Canon 50mm f/1.4 and f/1.8 lenses, we've found the f/1.8’s autofocus system to be much more accurate and reliable than its older sibling. Sharpness is also better than from Canon’s 50mm f/1.4 lens, from the centre to the edges.
Colour fringing is minimal at wide apertures and negligible at other apertures. There’s a little more distortion than with some rival lenses, but it’s rarely noticeable. Considering its accessible pricing, this lens is a great value budget buy.
Nikon F & Z 50mm lenses
Nikon's standard prime for its full-frame mirrorless Z cameras packs a 12-element optical stack which includes two ED glass elements as well as two aspherical elements to boost contrast and vibrancy.
Externally, the Z 50mm is noticeably bigger and heavier than a good old F-mount Nikkor AF-S 50mm f/1.8G, but compared with some F-mount 50mm alternatives from Sigma and Tokina, it’s pleasingly portable.
The lens barrel features just a single AF/MF switch, but the wide, tactile and precise manual focus ring isn’t redundant if you’re using autofocus, as it can also be set in-camera to adjust exposure compensation or ISO sensitivity.
Nikon has made much noise about the Z-mount's larger 55mm inner diameter and shortened distance between lens flange and image sensor, versus Nikon's F-mount. It's all supposed to add up to increased image quality.
This isn't just hype though, as the Z 50mm is terrifically sharp, only fractionally down on the significantly pricier Z 35mm f/1.8 S, and that’s the sharpest lens we’ve ever tested.
Aberrations are practically non-existent at any aperture, as is distortion, and the lens's stepping motor autofocus never missed its mark in our testing.
Up to now, if you wanted a Nikon Z-mount prime faster than f/1.8, you'd have to remortgage your house and fork out for a Nikkor 58mm f/0.95 Noct. When compared to that lens, this 50mm f/1.2 S could almost be called cheap. However, there's no getting around the fact that at 150mm long and over 1kg in weight, this is one hefty 50mm prime. This 17-element pro lens incorporates advanced coatings like anti-reflection ARNEO and Nano Crystal Coat, along with a 9-blade rounded diaphragm. The exterior is fully weather sealed and features a video-friendly silent control ring, along with a customisable Fn button and OLED info panel that displays important data.

Compared with a Nikon-fit Sigma 50mm f/1.4 DG HSM | A or a Zeiss Milvus 50mm f/1.4, Nikon’s own-brand lens is only half the physical length and about a third of the weight. It’s simpler than the Sigma, with eight rather than 13 optical elements, and rather less robust than the metal-jacketed Zeiss.
A further sign of the downsizing is that the Nikkor only has a 58mm filter thread, which is quite small for a 50mm f/1.4 lens. The straightforward optical path doesn’t contain an aspherical element (as featured in Nikon’s more budget-oriented 50mm f/1.8), and there are neither any ED (Extra-low Dispersion) elements nor any Nano Crystal Coat.
Autofocus accuracy is more critical in very wide-aperture lenses and the Nikkor does well in this respect, unlike Canon’s f/1.4 counterpart. Sharpness is average at f/1.4, but stop down to f/2.8 and this lens delivers superb sharpness across the entire image frame.
Lateral chromatic aberrations are minimal, though longitudinal fringing is present when wide-open. A nine-blade diaphragm helps to maintain smooth bokeh when stopping down a little. The only weak link is distortion, which is worse than we'd like for a standard prime. Overall, this lens is worth the extra outlay compared with the less expensive Nikon AF-S NIKKOR 50mm f/1.8G optic.
Sony E 50mm lenses
Sony's 50mm lens range is now very extensive, but we reckon its latest 50mm f/1.2 G Master optic is the best of the bunch. Although it feels quite bulky on a Sony mirrorless body, it’s still fairly compact and reasonably lightweight for an f/1.2 lens. The weather-sealed construction feels of fully professional-grade quality, there are two customizable function buttons that fall naturally under the thumb in both landscape and portrait orientation shooting, and the manual aperture ring comes complete with a de-click switch for stepless control during video capture. Unlike most ultra-fast lenses, the Sony maintains spectacular sharpness across the entire image frame, even when shooting wide-open. Bokeh is beautifully smooth and both lateral and axial color fringing are very negligible. There’s noticeable vignetting when shooting at f/1.2 but this pretty much disappears by f/2, and automatic in-camera correction is available anyway.
The Sony FE 50mm f/1.4 is the lens that is most suited to most Sony users, with its impressively light and compact build, however, it does not compromise one bit on optical quality, and this lens is almost perfect when it comes to sharpness in the center with only a small falloff towards the edges of the frame and some vignetting wide open, this lens gets almost full marks.
If you don't need the extra aperture stop, (which most shooters don't) or the added size, weight, or considerable cost of the FE 50mm f/1.2 GM, then the Sony FE 50mm f/1.4 will serve you perfectly.
The lens is expensive when compared to third-party glass that will achieve similar results, however, not with quite the same size and weight, lightning-fast autofocus, and reliable moisture-resistant construction that this lens offers.
Read our full Sony FE 50mm f/1.4 GM review.
Unlike many high-profile 50mm lenses with very fast max apertures, the FE 50mm f/2.5 is extremely small, extremely light and extremely practical. It can go places where you just wouldn’t take a bigger lens: with a lens this size you can shoot all day without getting arm-ache. Its maximum aperture of f/2.5 might sound very tame by today’s standards, but it’s still faster than even a pro zoom lens, while being a fraction of the size and cost. Performance-wise, this lens is just terrific. Sharpness is sensational, especially between f/2.8 and f/5.6, and chromatic aberration is almost invisible. The dual linear AF motors do their work silently, smoothly and quickly, and though there no stabilisation, all current Sony A7 (and A9) cameras have in-body stabilisation anyway.
The original edition of the Samyang AF 50mm F1.4 FE II was Samyang’s first ever autofocus lens, launched in celebration of the company’s 50th year in the business. Five years down the road, the Mark II features a new and improved autofocus system which is faster and more consistently accurate. Although relatively compact and lightweight for a modern 50mm f/1.4 lens, the Samyang packs some impressive features. Its new linear stepping motor-based autofocus system is super-fast for stills capture and works well for Sony’s face- and eye-detection AF, complete with highly effective tracking. It also enables smooth autofocus transitions for movie capture, the latter with minimal focus breathing, so the focus position doesn’t change when you adjust the aperture.
If f/1.4 is fast enough for your purposes and you don't quite fancy the asking price of the G Master lens above, the Sony Zeiss Planar T* FE 50mm F1.4 ZA is an excellent choice. It's a bulky, heavy lens, designed around the tried-and-tested Zeiss Planar concept designed to enhance image quality. In our review, we found center-sharpness, contrast and color fidelity of the lens to all be absolutely exceptional, and the quality of the bokeh to be delightfully smooth and creamy thanks to the 11-blade diaphragm. Is it a bit of a monster for 50mm, in terms of both size and price? Yes, but there's a lot going on under the hood here, and it's a credible alternative to the G Master.
Not everybody has the money for G Master and Zeiss lenses, and if you just need a simple 50mm for your Sony camera that'll get the job without costing the earth, here it is. The Sony FE 50mm f/1.8 performed well in our tests when we subjected it to a full review, with good sharpness and distortion control. Things do soften up when the lens is wide open at f/1.8, and there is some severe vignetting at this aperture, but otherwise performance is pretty excellent. One thing to be aware of though is that the autofocus is quiet but not silent, which will be a concern if you're planning to shoot video.
All right, we'll wait until you're finished fainting at the price tag. All done? Right – while we're going to admit that this expensive lens is not for everyone, we have to also be fair and say that it is one of the sharpest lenses we've ever tested – ever. The Leica Summilux-SL 50mm f/1.4 ASPH is ludicrously well constructed, inside and out, and the reason it weighs more than a kilogram is because it's packed with some of the finest glass in optical engineering. If you need the best of the best to pair with your Leica L-mount camera, this is the buy to make – it's absurdly sharp even with the aperture wide open or stopped fully down, and in the mid-range it's simply scintillating. What a lens.
Fujifilm X 50mm lenses
Available in black or silver, there’s no denying that the Fujifilm XF50mm looks a bit pricey for an f/2 lens. Indeed, it has the slowest aperture rating of any lens in this test group.
However, it’s impeccably built, with comprehensive weather-seals, a physical aperture ring for refined Aperture Priority and Manual mode shooting, and a high-grade optical path that includes an aspherical ED (Extra-low Dispersion) element. The nine-blade diaphragm is well-rounded.
Autofocus is virtually silent. As with other ‘stepping motor’ systems, the focus ring is electronically coupled and, in this case, enables particularly precise manual control.
On Fujifilm X cameras, the lens has an effective focal length of 75mm and delivers a tight depth of field at f/2, making it a great portrait lens. Wide-open sharpness is excellent across the entire image frame, there’s very good resistance to ghosting and flare, and fringing is practically impossible to spot at wide apertures. There’s a very slight hint of pincushion distortion, but it’ll generally go unnoticed.
Micro Four Thirds 50mm lenses
Micro Four Thirds lenses only need to produce a relatively small image circle, and this Panasonic is typically compact and very light at only 130g - a fraction of the weight of some premium prices for DSLR cameras.
With its effective focal length of 85mm, the Panasonic is ideal for portraiture and the f/1.7 aperture enables a fairly tight depth of field. It’s well-engineered and features an optical image stabilizer.
This makes it ideally suited to Panasonic cameras; for Olympus bodies with sensor-shift stabilisation, we’d go for the Olympus M.Zuiko Digital 45mm f/1.8.
Autofocus is quick and accurate, while color fringing is essentially a non-issue, as even Raw files are automatically corrected. There’s the merest touch of barrel distortion but you’re unlikely to notice it. Sharpness is good, but not great, and many other rival optics manage better centre-frame sharpness.
With its relatively ‘telephoto’ effective focal length, this lens's optical stabilization will clinch the deal for MFT shooters whose cameras don’t have an in-body stabilizer.
The HD Pentax D FA* 50mm f1.4 SDM AW represents Pentax's the first in a new generation of Star-series optics that have been designed for use with the both the full-frame K-1 and K-1 Mark II DSLRs. Designed to deliver the highest in-house standards both for current and future Pentax DSLRs, this 50mm lens features Aero Bright Coating II - a lens-coating nanotechnology employing a super-low refractive film fabrication process, while the lens also incorporates three super-low dispersion glass elements and one aspherical element. A large and heavy lens at almost 1kg, it's both dust-proof and weather-resistant, as well as enjoying a newly developed ring-type SDM (Supersonic Direct-drive Motor). It's pricey, but if you're looking for a high quality standard prime for your full-frame Pentax DSLR, this is the best 50mm lens you can buy.
So-called ‘portrait primes’ are often fairly big, heavy and expensive, but this Pentax lens is none of those things. At just 1.5 inches long and 122g in weight, it’s really compact and lightweight, yet still delivers a 76.5mm effective focal length with a fast f/1.8 aperture on Pentax APS-C format DSLRs for which it’s designed. It lacks an autofocus motor and is somewhat basic in some respects but that’s reflected in the refreshingly affordable purchase price. Read our full SMC Pentax DA 50mm f/1.8 review.
Multi-mount 50mm lenses
Sigma’s previous 50mm lens was renowned as being a heavyweight, but the replacement ‘Art’ edition really piles on the grammes. It gains 50 per cent in physical length and rises from 505g to 815g in weight.
The main reason for the Art lens’s weight gain is that it has a much more complex and sophisticated optical path than its predecessor, based on 13 rather than eight elements. These include one complex aspherical element and three SLD (Special Low Dispersion) elements.
Build quality feels superb, although there are no weather-seals and the focus ring doesn’t quite have the tactile fluidity of a lens like the Zeiss Milvus. But you can count on the Sigma’s autofocus system to be fast and accurate.
The Sigma is amazingly sharp, even at f/1.4, along with soft, creamy bokeh. Sharpness only drops off at f/1.4 in the extreme corners of the image frame. Colour fringing is very minimal at any aperture, even at the corners of the frame, and barrel distortion is absolutely negligible.
Third-party lenses can often be a way to snag some real bargains – case in point, this inexpensive lens for full-frame Nikon Z and Sony FE cameras that nevertheless punches above its weight. The Yongnuo YN50mm F1.8Z DF DSM is built to a pleasing standard of quality, and has a few clever handling features like the two L-fn buttons that can be assigned to your preferred functions. Optical quality is generally pretty good – there's some noticeable pincushion distortion and lateral chromatic aberration, but both can be corrected pretty easily with software. We do wish the bokeh was a little less fidgety – there are definitely smoother 50mm f/1.8 lenses out there. Overall though, this is an impressive package.
Designed to be the start of a high-end Opera series, this lens is positioned above the company's AT-X lens line and rivals Sigma and Tamron’s latest premium offerings.
Inside is a 9-element optical stack that contains three SD (Super-low Dispersion) elements and one aspherical element to minimise chromatic aberrations, while a new ELR (Extremely Low Reflection) coating reduces ghosting, flare and reflections.
The Opera 50mm is dust and moisture resistant, and though its AF system is of the ring-type ultrasonic variety rather than a more modern stepping motor design, it's fast and reliable.
But it's the Opera's image quality that impresses most. Sharpness is excellent, even wide open at f/1.4, becoming simply sublime from f/2 right through to f/11. Purple fringing is very well controlled, right at the corners of the frame, and you can forget about distortion, as there simply isn't any.
The Opera 50mm will cost you a sizeable chunk more cash than the already-pricey Sigma 50mm f/1.4 DG HSM | A, but it is the new sharpness benchmark for a Canon or Nikon DSLR standard prime.
Autofocus cameras have been around since 1977, so it might seem strange that Zeiss is still doggedly making manual-focus lenses. However, the range of Milvus prime lenses certainly gives a hands-on, feel-good factor.
The 50mm f/1.4 is typical in having a beautifully engineered metal barrel and a full set of weather-seals. The optical design is based on Zeiss’s legendary Distagon principles. The long rotational travel of the focus ring helps focusing precision, and its super-smooth fluidity makes focusing a joy.
The Nikon edition has a physical aperture ring with a de-click facility, to enable smooth aperture transitions during movie capture. This ring is absent on the Canon edition.
Living up to its reputation and price tag, the Milvus delivers gorgeous image quality. Wide-open, it combines superb contrast and stellar sharpness across almost the entire frame.
There's beautiful bokeh, and the lens maintains a lovely smoothness in defocused areas when stopping down a little. Colour fringing is almost a complete non-issue with this lens, even in the corners.
There’s a little more distortion than in Tamron's SP 45mm f/1.8 Di VC USD, but less than in competing 50mm primes from Canon and Nikon.
The super-fast 7Artisans 50mm f/1.05 combines impressive sharpness - even wide open at f/1.05 - with sumptuously smooth bokeh. When it comes to image quality, that’s the perfect combination for a lens of this class. Added bonuses are that both lateral and longitudinal color fringing are negligible, and barrel distortion is very slight. The lens lacks autofocus and has no built-in electronics, so focus and aperture have to be adjusted via the on-board control rings. Even so, it’s amazingly small and lightweight for such a fast-aperture lens, is strongly built and has refined handling characteristics, making it standout value for money.
How we test lenses
We test lenses using both real world sample images and lab tests. Our lab tests are carried out scientifically in controlled conditions using the Imatest testing suite, which consists of custom charts and analysis software that measures resolution in line widths/picture height, a measurement widely used in lens and camera testing. We find the combination of lab and real-word testing works best, as each reveals different qualities and characteristics. See more on how we test and review at Digital Camera World.
