The 50mm T1.5 AS UMC Cine DS Lens for Sony E Mount from Rokinon is a fast manual focus prime lens. It is compatible with APS-C and full frame E-mount cameras, having a full frame focal length equivalent of 75mm with APS-C sensors. 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.

question
Comparing the specs of this lens and the Rokinon 50mm f/1.4 AS IF UMC Lens, is there much difference between the two other than their minimum focusing distance? I.e. What's the reason for this lens being close to $200 more expensive than its AS IF sibling? Cheers.
I believe one difference is the housing - the Cine DS lenses all have the gearing for the focus and aperture rings in the same place relative to the lens mount, so that you don't have to reset your follow focus when you change lenses. There may be other differences in coatings, etc.

is this mean that I do not need metabones to using this lens? since its already for MFT?
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

What is the difference between the AS UMC and the DSX lines?
The difference between the Rokinon AS UMC DS series and the Rokinon DSX series is that the Rokinon DSX series has weather sealing and a 9 blade iris. The Rokinon AS UMC DS series does not have weather sealing and has only an 8 blade iris.

question
What is the focal length equivalent for Super 35mm CMOS on Canon EOS C100 Mark II?
Super35 is, for all intents and purposes, has the same angle of view as APS-C. With both of these, there is a 1.6 difference in their angle of view as compared to Full Frame. So on the C100's Super35 sensor a 50mm will have about the same angle of view of an 80mm lens on a Full Frame sensor.

Can I use this with a Blackmagic Pocket Cinema 4K or do I need an adapter ring of some sort?
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.
