SLR Magic 12mm for Pocket

I'm on the Noktor website just about ready to order an SLR Magic Hyperprime Cine 12mm T1.6.
I have the option between the one listed above at 549$, or the Cine 12mm T1.6 / with 77mm HOOD RING at 599$.
Question: For this lens to work on the Pocket cam, do I need to HOOD RING?
Thanks for anyone who can help answer this.
