Rokinon 50mm T1.5 Cine DS Overview

The 50mm T1.5 AS UMC Cine DS Lens for Canon EF 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 EF 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.

Can I use this with a Blackmagic Pocket Cinema 4K or do I need an adapter ring of some sort?
Asked by: Ryan
This is an EF mount lens and the Pocket Cinema Camera 4K has an MFT mount. You would want the Rokinon 50mm T1.5 AS UMC Cine DS Lens for Micro Four Thirds instead, BH #RO5015M43. https://bhpho.to/2Zfkf2g

is this mean that I do not need metabones to using this lens? since its already for MFT?
Asked by: Indra
Correct, this is an MFT mount. Connecting directly to a typical MFT base should get you close to a 100mm focal length range equivalent. If you were looking for this to be 50mm equivalent it would need some sort of metabones reducer, and maybe a different mount type lens to go with that to achieve it

question

is this lens compatible with the Sony NEX5T?
Asked by: Anonymous
As the Nex 5T has the Sony e-Mount the lens is compatible. All lenses with e-Mount fit to Sony cameras with e-Mount. As the lens is a manual focus lens, there is no AF.

question

Does this version produce sharper and better image quality than the 1.4 photo lens? Different optics?
Asked by: Jim
This is a cinema lens. There are several differences and none of them are to do with sharpness. First cinema lenses are measured in T stops not F stops. This means that they calculate into the equation how much light the optics lets through (T stops let in more light than F stops). Second, the gear rings are different so that you can put a follow focus on it. Third it has a click less aperture for smooth adjustments during filming. Fourth it has the UMC coating which gives you a little different, more cinematic colors.A Rokinon lens will be as sharp as a Rokinon lens is. That's not a knock, I think they're pretty great for their price.
