I have a Canon M50 and mount this lens on it with the shooting set to M, but no response in shooting, why?
Asked by: Cary
You would need to set the camera in the Menu in the Custom Functions section to shoot without a lens. The function is called Release shutter w/o lens, it needs to be set to enable.

question

Is this lenses all manual (focus and iris)? Can it be used with BlackMagic 2.5k mount MFT?
Asked by: Anonymous
The BlackMagic Cinema MFT mount camera requires use of manual focus and manually adjustable aperture lenses. The black Samyang Reflex 300mm f/6.3 ED UMC CS 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.
