Q: 1. Is this lenses all manual (focus and iris)? Can it be used with BlackMagic 2.5k mount MFT?

A: The BlackMagic Cinema MFT mount camera requires use of manual focus and manually adjustable aperture lenses. The black Rokinon Reflex 300mm f/6.3 ED UMC CS Lens will mount on the camera but will not allow you to adjust the aperture of the lens as this lens has a fixed aperture of f6.3. The benefit of the camera using the MFT mount is the availability of adapters which will allow one to mount various manual focus/manual aperture lenses to the camera.
