Samyang 50mm f/1.4 overview

  • 1Description

Utilizing a "normal" field of view and a fast f/1.4 maximum aperture, the 50mm f/1.4 AS UMC Lens for Canon EF from Samyang is optimized for effective low light shooting, fast shutter speed capture and shallow depth of field control. When used on cameras with an APS-C format sensor its 35mm focal length equivalence is 80mm.

The optical design of the lens consists of 9 elements in 6 groups including one hybrid aspherical element and one aspherical element to reduce chromatic aberrations. Also, lens elements are coated with an Ultra Multi-Coating to improve light transmission and minimize flare and ghosting. Eight diaphragm blades create a circular aperture for more attractive out-of-focus highlights.

As a manual focus and manual aperture lens, it provides a rubberized focus ring and clear aperture, distance and depth of field markings. Additionally, an included petal-shaped lens hood blocks unwanted light and protects the lens.

Standard length prime lens for full frame cameras, also compatible with APS-C cameras on which it has a 35mm focal length equivalence of 80mm

    Samyang 50mm f/1.4 reviews

    50mm f/1.4 AS UMC Lens for Canon EF is rated 3.8 out of 5 by 5.
    Rated 5 out of 5 by from Great quality, smooth focus ring, excellent value for money Love this lens! I own a video production company and prior to this had the Canon 50mm f/1.8 STM and hated it. Pulling focus with a STM lens is the most terrible thing you can try to do. Pulling focus with this is super smooth and since it is longer as well it is very precise. Build feels nice and the hood snaps into place real well. Ran some tests to see how it preformed with sharpness, contrast, vignetting, and color and liked the results. Would never shoot wide open at f/1.4 unless I wanted that crazy look, but stopping down to f/2.0 gets rid of a lot of vignetting and is totally usable. The sharpness is super good all the way from f/2.0 all the way up. Great value for the money!

    Rated 5 out of 5 by from Samyang brings the pain! I use this for my short films, weddings and street photography. People really are underestimating Mr. Samyang. I use this beautiful lens on my 6d and 70d.I like the look and feel of lens. It's big and is a blast to manual focus! I perfer manual focusing instead of auto focus. I also love the price! I haven't found anything I did not like about this lens. I also purchased the 85 & 35mm samyang. No complaints here.P.S. The aperture is adorable. I set my camera to video mode to take pictures with this lens. That is how it works for me. I'm sure there are other ways.

    Rated 5 out of 5 by from Superb build and image quality One of the neat things about this lens, and something that I consider a perk, is the fact that it's fully manual. Typically, this might be seen as a drawback as a lot of the features of lenses now are automated but this just forces you to think differently about the type of photo you want to take, and how you should take it. Not to mention, it also lets you engage with your camera more as well. The design of it is also really elegant as well. I'm a huge fan.

    Rated 2 out of 5 by from Not Great for Astrophotography This is the second copy I have tried (Rokinon version last time) and was planning to use this for's not up to the task! This Samyang copy had a minor de-centered element and on an APS-C the aberrations in the corners was not much of an improvement over the Canon 50mm f/1.8 II. The overall feel of the manual focus and aperture controls are nice and this may make a nice lens for other uses but not astrophotography. Returning the lens and off to consider the Sigma 50mm f/1.4 DG HSM ART!

    Rated 2 out of 5 by from Not a good lens for Astrophotography This might be a good lens for portraits, but not for Astrophotography. Has too much distortion and coma in the corners and edges, especially at the wide open f stops. Apertures 1.4 to 4.0 are not good. Starts getting better at 5.6 and 8.0, but for night photos, you want to use the lower f stops. Center of image is generally good. It would just require too much cropping to get rid of the bad corners and edges.
