Rokinon 50mm f/1.4 Overview

The 50mm f/1.4 AS IF UMC Lens for Canon EF Mount from Rokinon offers a standard 50mm focal length in the full frame format and a very fast f/1.4 maximum aperture 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. Its internal focus system will not extend the length of the lens while focusing and an included petal shape 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

question

Is there no difference between this and the Samyang? I see that this one has the inclusion of IF in the name for Internal Focus . That sounds like a made up word for manual focus though. Am I right? A big difference I see is $60-$100 which I'd like to save.
Asked by: Robert V.
There is no difference between the two lenses. Rokinon and Samyang are both made in the same factory by the same company.

Is the aperture ring on this lens declicked for cine/video work ? What is the difference between this lens & Rokinon’s Cine line of lenses ? I would use as a prime on my FS7
Asked by: Christian
It is not, this does not offer a de-clicked aperture. That is one of the main differences between this and a Rokinon Cine lens like B&H # RO5015TSE. Rokinon Cine Lenses offer a de-clicked aperture and have lens gears built in for use with Follow Focus Systems. https://bhpho.to/2psJeOp
