Rokinon Cine DS Focal Length Question

Hi everyone!  I'm just starting my adventures in shooting video on MFT and have a basic question about focal length, crop factor, etc...
I'm looking at buying a few Rokinon Cine DS lenses for MFT mount and want to make sure I'm properly understanding the focal length conversions.  My basic understanding is that it's a 2x crop factor from full-frame sensors.  i.e. a 24mm lens on a MFT camera will have the same framing as a 48mm lens on a full-frame camera.
Specifically my question is about finding a lens that closely matches the field of vision of the human eye.  Without going into a discussion about what this ideal length would be, let's just accept for now the time honored tradition that a 50mm lens is the most 'natural' focal length. 
Rokinon Cine DS lenses come in 10mm, 12mm, 14mm, 16mm, 24mm, 35mm, 50mm, 85mm, 100mm, and 135mm regardless of lens mount.

Am I correct that if I bought the 50mm EF mount lens and put it on my Canon 6D, and the 50mm MFT mount and put it on my GH4 and compared the two the images. the GH4 could be cropped 2x (appearing similar to a shot taken on the 6D with a 100mm lens)?
And, to get back to my point, if I wanted a natural, 50mm-esque lens for my GH4 I would then have to go for something half the focal length?  (In this case, the 24mm MFT mount being the closest.)
Thank you, in advance, for you help and insight!
