Rokinon 50mm f/1.4 Overview

The 50mm f/1.4 AS IF UMC Lens for Sony E-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 capture, fast shutter speed shooting and shallow depth of field control. When used on cameras with an APS-C format sensor its 35mm focal length equivalence is 75mm. 

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 wide, 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.

Rokinon 50mm f/1.4 Reviews

Excellent for astrophotography

By Dave

I purchased this lens for use in astrophotography and I have not been disappointed. It is easy to use (it is manual) and feels solidly built. My first night using it I was able to capture excellent astro images. Even stepped down to f/2.8 the images appear crisp and clear to the corners

Great lens!

I really like Rokinon manual prime lens. This is one of three lens I use for night photos on a full size sensor. I have three others I use for my APSC camera. For the price, these are really good. Fast lens for quick shots of the Milky Way or others.

For me, not quite sharp enough

I use this lens on a Sony FS5 video camera, and only use it for doing video interviews in 4K. When opened up to it's max (1.4) or near it, I really can't get this lens to be crisp. Have to have a sharp image to start with... Going to sell it and upgrade to a Sony sonnar or zeiss lens and spend the money. You get what you pay for as they say

great lens

This lens is a great buy, low price for great quality. The build quality is excellent, feeling very solid with its all metal build and comfortable focus ring. The focusing capabilities are outstanding, with very precise measurements and relatively close minimum focusing distance. At f1.4 the image can be a little soft in the corners, but nothing so extreme that the image becomes useless, and for the price as low as it is, it's definitely a deal. Keep in mind this lens is fully manual focus so if you are a sports or nature photographer, this lense is not for you. Overall I'm very satisfied with my purchase, and recommend this lens strongly. DONT FORGET CROP FACTOR

Really like this lens

Bought the lens barely two weeks ago and I love it. I've used mostly to shoot bands in small clubs and bars. The wide aperture is perfect for the low light conditions and the images stay sharp. Focus peaking with the Alpha 7RII helps with the manual focusing. Sturdy, fast and sharp.

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

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.
