Offering a natural perspective along with a fast maximum aperture, the EF 50mm f/1.4 USM from Canon is a versatile normal-length prime characterized by its bright f/1.4 aperture to suit working in low-light conditions and for producing shallow depth of field imagery. This lens also features a Gaussian optics design, along with two high refractive index elements, to control spherical aberrations and distortion for high sharpness and clarity. A Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast and color accuracy when working in difficult lighting conditions. Complementing the optical design is a micro USM, which enables quick and quiet autofocus performance along with full-time manual focus control.

- EF-Mount Lens/Full-Frame Format

Canon EF 50mm f/1.4 USM Reviews
Essential lens
You cannot live without this lens. Hits the sweet spot for build quality and affordability. Do not overlook this one.
Wonderful full frame lens
First lens for my Canon 1dx II, the combination in low light is better than I expected. The 1.4 aperture give flexibility but I rarely use it with 1dx auto iso.
Upgraded from the Canon EF 50mm f/1.8 STM Lens
I bought the Canon EF 50mm f/1.4 USM Lens as an upgrade from the old Canon EF 50mm f/1.8 STM Lens I was using. This one has been better, sharper and more crisp. I love it!
Gorgeous characteristic!
Needed a 50mm for my BMPCC6k Pro and I'm happy I chose this lens. There are some beautiful colors and warmth that come from this lens compared to a sigma or other brand. Unfortunately operates as a ~85-100mm because my camera is not full frame, but it's a lovely lens to have in your bag regardless.
Great Lens
We bought a 5D Mark IV used and needed a lens. This was available and we both like 50mm so we picked it up. So far we are both in love with the image quality and versatility. Sometimes the autofocus hunts or misses the target. But in general it's fast and accurate and has helped get great images. It's great in low light and gets sharper if you close it up a bit. So far we have done portraits and people photography as well as a few days wandering around the city. It's lightweight and compact which is nice on such a big camera body. Definitely recommended.
So good, especially if your subjects are human
This was the first fixed lens I purchased and although I loved the image quality immediately, I was prompted to write this review four years later because in going through my image archive, time and again, it is the images captured with this lens that really catch my eye. I have subsequently bought some L series glass, so this 50 1.4 has been on my camera (80D) less frequently of late, but now that my archive review has reminded me, it'll be back on regular rotation. Especially excellent for flashless indoor shooting (I hate the irritation of flashes and the way they effect an otherwise relaxed social gathering), but also great in full daylight. The extra shallow depth of field is fun to play with, but the image quality is indiscernible (to my eye) from that of my precious 70-200 IS 2.8. I've never used the nifty fifty (1.8) so maybe the extra cost for this one won't be worth it to some, but the (utterly non-scientific but nonethess striking) comparisons provided by my retrospective review of about 30,000 images taken over four years lead me to recommend this lens wholeheartedly to anyone who wants to inobtrusively capture intimate, butter-smooth images, particularly of humans in social/street settings.
Little gem!
This was one od my first lenses bought some 15 years ago and its still in my wedding bag. Its a small gem, weighs nothing and delivers superb quality pics from f2.0-2.2. I had the 50 1.2 but eventually sold it as it was less practical, and my 35 1.4 works better in super low light. I had a chance to compare with the newer 50 1.8 but didn't like the bokeh there, the 50 1.4 delivers dreamy smooth bokeh. If you really need to shoot below f1.8-2.0 then you need to look elsewhere (RF 1.2 or sigma but these are heavy beasts)
50 mm 1.4 USM
Wonderful images, very compact, my first lens for my 1dx ii, low light is wonderful, I will stick with Canon lenses
