If you're a regular on UHH, you've probably seen a comment that goes something like, "a friend said I should get a 50mm prime lens." I'm not trying to argue for or against that idea. What I can say is a 50mm lens, on a full-frame body, roughly mimics the field of view of your eyes (use a 35mm lens on a cropped body for the same field of view). Just grab your camera and mount a lens that includes 50mm (or 35mm) and raise and lower the camera from your eye to confirm.
This post is less about 'why' anyone needs a 50mm prime, or any prime lens for that matter. Rather, what is important to me is the capability of a lens and the images it will deliver. I don't care if the lens is cheap or expensive, as long as it will deliver sharp images. Filtering by only the 50mm focal length, my Lightroom statistics came back at 6000+ images at 50mm, more than twice the amount of the next most popular focal length of the 241 discrete focal lengths in the catalog.
For me, a 50mm prime lens is a must. The images presented in this post intermingle my two Canon EF 50mm primes. I've never used the 'mid-point' f/1.4 model, so this bake-off is the L-series against the original 1987 f/1.8 'plastic fantastic'. Both lenses were purchased used, the EF 50mm f/1.8 being first acquired in 2013. In my earlier film life, I had used the manual focus Canon FD 50mm f/1.8 on film cameras going back to the early 1980s.
As you consider the various images and similar subjects, you can launch the URL links to see the lens model from the host Flickr page or just guess from the image which lens was used.

The neon sign is a nostalgic icon of Route 66. If a business wanted to stand out from the crowd, they would need to do something pretty special. Starting in 1926, Route 66 passed through the nearby Petrified Forest and downtown Holbrook, Arizona. Tourism started taking over the local economy.
Check-in The Chicago Theatre is a landmark theater located in the downtown Loop area of Chicago, Illinois. The distinctive Chicago Theatre marquee appears frequently in film, television, artwork, and photography.
Chicago Theater The Pro Football Hall of Fame is located in Canton, Ohio. The Hall of Fame Game, the annual NFL preseason opener, is played at the stadium adjacent to the Hall, and officially kicks off the NFL preseason.
NFL Hall of Fame I use my two EF 50mm primes rather interchangeably, where the size / weight of what I want to carry nearly always determines which I pick. There are differences in the lenses, where for apertures f/1.2 to about f/2.5, the EF 50mm f/1.2L USM is the clear winner, and for much of that range, the only competitor.
50mm prime lenses have a pleasing perspective that matches the field-of-view of the human eye. They take photos that don't have the sweeping lines or distorted perspective of images taken with wide angle lenses, or the compressed perspective created by telephoto lenses.
Delicate Arch 50mm lenses are simple. They tend to have six to eight elements inside, where zoom lenses may have twice the number of elements. The 50mm f/1.8 model is likely to be the cheapest lens in the entire line for every lens manufacturer. Most 50mm lenses represent excellent value for money.
Montrose BeachFor the EF mount, Canon makes three 50mm prime lenses (plus a 50mm macro lens). The current f/1.8 model is the EF 50mm f/1.8 STM that sells new for $125. All the EF 50 f/1.8 models are small and light weight. They seem not to add any additional weight to the camera. The current STM version weights just 5.6 oz / 160 grams.
Blue Mesa With a fixed focal length lens, you have to move around to get a different perspective rather than turning the zoom dial. As you move around looking for the best point-of-view, you have a tendency to more closely consider your subject.
Montpelier The L-version comes in at 20.9 ounces / 592 gm. It features weather sealing, 8 rounded aperture blades, lens hood and pouch, and the fast AF speed you'd expect of an L-series lens, as well as the 10x price over the f/1.8 version.
Carlsbad Caverns National Park The newest EF 50 f/1.8 STM version returns to a metal lens mount, a feature of the original 'mark I' version of the lens used for these comparisons. The EF 50 f/1.8 II was the true 'plastic fantastic', although the optical formula remained the same as the 'mark I' it replaced.
Marsh Sunrise In my kit bag, if the equipment isn't being used, it gets sold. After shooting mostly the 50L in 2018, I got it into my mind the EF 50 f/1.8 wasn't delivering as good of images and he was a candidate for selling. For 2019 the f/1.8 lens was used almost exclusively for 50-prime situations. And when the results from the year were considered, I was embarrassed to admit I ever had a concern about this lens.
For the selection of images in this post, I used the metadata filters in Lightroom to identify landscape images from these two lenses. I was surprised to see over a period of years going back to 2013, a few subjects would reoccur, such as these petting zoo goat close-ups.
Petting zoo goat The 50mm prime is a useful portrait length on APS-C sensors, giving a 75mm - 80mm equivalent field of view.
