The 50mm T1.5 AS UMC Cine DS Lens for Nikon F Mount from Rokinon is a fast manual focus prime lens. It provides a very fast maximum aperture of T1.5 for effective low light capture and shallow depth of field control and an 8 blade iris for attractive bokeh. Optimized for cinema and video applications, the focus and aperture control rings are outfitted with industry standard gearing, which provides an interface for working with a traditional follow focus. The aperture control ring has also been de-clicked, which enables smooth iris pulls. In addition, bright aperture and distance markings are printed on the lens barrel facing laterally to facilitate easier control by a focus puller.

The 50mm has a minimum focus distance of 1.5'. Internal focusing minimizes the effects of lens breathing, which insures a more consistent angle-of-view when adjusting focus. The lens is composed of 9 elements in 6 groups, including one aspherical element and one hybrid aspherical element to reduce aberrations. In addition, a lens multi-coating helps to improve light transmission reducing flare and ghosting. The filter thread diameter is 77mm.

With this 50mm lens, Rokinon introduces the DS series of cinema lenses, unifying their cine lenses in more than just name. Each of the DS branded lenses will offer the same alignment of their geared focus and aperture rings so that follow focus and other rig accessories won't need re-adjustment when swapping lenses. Also, each DS lens is tested to be color matched with the other lenses in the series and provide the same color and contrast when shooting video. Lastly, the lenses are marked with focusing scales on each side of the barrel for easier adjustment from either side of the camera.

Standard length manual focus prime lens for F mount cameras.
Functional as still photo lens but optimized for cinema and video shooting with geared aperture and focus rings, de-clicked aperture for smooth exposure transitions and laterally printed aperture and distance markings. The 50mm T1.5 is part of the DS series of cine lenses, sharing characteristics and features that unify the series and make it easier for users to swap out lenses when shooting video. Each DS lens provides aligned focus and aperture rings so that readjustment of the follow focus is not necessary when switching lenses. Also each lens has been tested to match color and contrast for a consistent look and less potential post-processing. Finally, all DS lenses print focus scales on each side of the lens barrel for ease of use from both sides of the camera.
Very fast T1.5 maximum aperture for effective low light capture and shallow depth of field.
Internal focusing system with 9 lens elements in 6 groups.
One aspherical and one hybrid aspherical lens element control aberrations and improve sharpness throughout the frame.
Lens multi-coating improves light transmission and reduces flare and ghosting.

    50mm T1.5 AS UMC Cine DS Lens for Nikon F Mount is rated 4.7 out of 5 by 7.
    Rated 5 out of 5 by from Nikon Mount is the one to get My set of these cine lenses include 16mm, 24mm, 35mm, 50mm and 85mm. I'm using this set on several different APS-C cameras which is pretty close to 35mm movie frame size. The secret to having one set of lenses fitting several bodies is to get the Nikon mount and adapters. You don't need to worry about automation working, they are all manual lenses. One gotcha is that the Nikon mount lenses focus in the opposite direction, no big deal but it was a surprise to me that the manufacturer did that to please Nikon shooters.

    Rated 4 out of 5 by from This is good lens I am pleased with this lens. It is sharp, even wide open. I would enjoy it if it were smaller, but for a 77mm diameter, it's relatively small and light.

    Rated 4 out of 5 by from first impressions The build is in line with the other Rokinon lenses. The focus is a bit stiffer than the other one (16,24,35,85) but still smooth. Optically it's a nice lens. Wide open it has some CA.

    Rated 5 out of 5 by from Should have purchased a set of these a long time ago Tested this against the Veydra E-mount 50mm and it did well. The visual results were pretty indecipherable as both lenses were sharp and professional feeling. I used this Nikon mount on my Sony FS7 with a Metabones Speedbooster so my angle of view was a little wider and a had a LOT of low light capability (1.5 T stop for Roki and the Metabones even improved upon that. 2.2 max aperture on the Veydra). For Cine/video shooting I don't like the reverse focus throw (Nikons don't match the motion of the rest of the free world). I continually rack focused the wrong direction out of habit. Ultimately I chose the Veydra over the NIKON Roki partly because of focus direction, but PRIMARILY because of the smoother, longer focus throw of the Veydra, AND the minimal breathing of the Veydra. BUT I would not hesitate to use this Rokinon on a professional shoot.

    Rated 5 out of 5 by from 50mm is a great lens! Really nice cinematic lens! I really like this lens I also have the 35mm I would say I use the 35 more than the 50 however the 50 comes in handy for when I need to get just a tad bit closer.

    Rated 5 out of 5 by from Great glass! This is a great lens. It's fast and a 50mm is a must have lens. I shoot training films and short form movies mostly. But I also use my cinema lens for photos. Buy it you will love it.
