Samyang further sells a V-DSLR cine version
of this lens. Its release in 2012 initiated the trend for the 8mm standard version with removable lens hood. Until then people tended to shave down the lens hood to use the lens on bigger format sensor cameras without vignetting as well.
The DH in version II abbreviates the detachable lenshood.
