Photographers of all stripes will swear by the best 50mm lenses. A perfect focal length for everyday shooting, 50mm lenses are neither too wide nor too long, allowing you to capture a naturalistic medium perspective that's great for all sorts of shooting.
Which, however, to choose? That is indeed the question of the day, as there are plenty of examples of 50mm lenses made by all the major manufacturers. Some are affordable and portable, while others are expensive and enormous, providing far superior image quality to the entry-level models. Which 50mm lens you choose will depend largely on your system, your needs and your budget.
We've put this guide together to help you find the right 50mm lens for you. We've included a range of specific lenses for each lens mount, and have also included a selection of third-party lenses that are available for multiple systems.

A word on equivalent focal lengths
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...
1. Nikon Z 50mm f/1.8 S
It may be a ‘standard’ prime, but its performance is anything but
Mount options: Nikon Z | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Stepping motor | Stabilizer: No | Minimum focus distance: 0.4m | Filter thread: 62mm | Dimensions (WxL): 76 x 86.5mm | Weight: 415g
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.
2. Nikon AF-S 50mm f/1.4G
A compact and light f/1.4 lens that's incredibly sharp across the whole image frame
Mount options: Nikon F | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring) | Stabilizer: No | Minimum focus distance: 0.45m | Filter thread: 58mm | Dimensions (WxL): 74 x 54mm | Weight: 280g
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 Nikon’s f/1.8 optic.
3. Canon RF 50mm f/1.2L USM
It may be pricey, but Canon's 50mm for the RF system is an astonishing performer
Mount options: Canon RF | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring) | Stabilizer: No | Minimum focus distance: 0.40m | Filter thread: 77mm | Dimensions (WxL): 89.8 x 108mm | Weight: 950g
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.

4. Canon EF 50mm f/1.8 STM
An unconventional choice for a Canon 50mm, but it's the smart buy
Mount options: Canon EF | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Stepping motor | Stabilizer: No | Minimum focus distance: 0.35m | Filter thread: 49mm | Dimensions (WxL): 69 x 39mm | Weight: 160g
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.
5. Samyang AF 50mm f/1.4 FE
A super-sharp autofocus prime for Sony A7 and A9 cameras
Mount options: Sony E | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.45m | Filter thread: 67mm | Dimensions (WxL): 74 x 98mm | Weight: 585g
Renowned for its quality yet reasonably priced manual focus prime lenses, Korean manufacturer Samyang has recently started making autofocus lenses, mostly for Sony’s full-frame E-mount fit.
There are currently five E-mount lenses to choose from, plus two Canon EF and one Nikon F. This 50mm optic gives the ‘standard’ perspective on Sony’s A7 and A9 cameras, with a fast aperture rating of f/1.4.
Physically, it’s about twice as long as Canon and Nikkor 50mm f/1.4 lenses for full-frame DSLRs. The solid construction features mostly metal barrel parts and, contributing to its hefty 585g weight.
This Samyang's performance doesn't disappoint. Sharpness is very uniform across the frame at f/1.4 and becomes excellent at f/2, where contrast is also excellent. Vignetting is quite severe until you hit f/2.8, but fringing is particularly negligible and there’s very little barrel distortion.
6. Fujinon XF50mm f/2 R WR
A relatively pricey prime for Fujifilm X cameras, but performance is fabulous
Mount options: Fuji X | Effective focal length: 75mm | Full-frame compatible: No | Autofocus type: Stepping motor | Stabilizer: No | Minimum focus distance: 0.39m | Filter thread: 46mm | Dimensions (WxL): 60 x 59mm | Weight: 200g
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
7. Panasonic Lumix G 42.5mm f/1.7 Asph P.OIS
A stabilised portrait prime for Micro Four Thirds cameras
Mount options: MFT | Effective focal length: 85mm | Full-frame compatible: No | Autofocus type: Stepping motor | Stabilizer: Yes | Minimum focus distance: 0.31m | Filter thread: 37mm | Dimensions (WxL): 55 x 50mm | Weight: 130g
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 stabiliser.
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 colour 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 stabilisation will clinch the deal for MFT shooters whose cameras don’t have an in-body stabiliser.
8. Tokina Opera 50mm f/1.4 FF
A 50mm prime of the highest calibre
Mount options: Canon EF, Nikon F | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.4m | Filter thread: 72mm | Dimensions (WxL): 80 x 107.5mm | Weight: 950g
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.
9. Sigma 50mm f/1.4 DG HSM | A
Top-drawer construction, along with superb handling and all-round performance
Mount options: Canon EF, Nikon F, Sony A, Sigma | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Ultrasonic (ring-type) | Stabilizer: No | Minimum focus distance: 0.4m | Filter thread: 77mm | Dimensions (WxL): 85 x 100mm | Weight: 815g
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.
10. Zeiss Milvus 50mm f/1.4 ZF.2
Who needs autofocus when image quality looks this good?
Mount options: Canon EF, Nikon F | Effective focal length: 50mm | Full-frame compatible: Yes | Autofocus type: Manual only | Stabilizer: No | Minimum focus distance: 0.34m | Filter thread: 67mm | Dimensions (WxL): 83 x 98mm | Weight: 922g
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.
