I had the grid for the BMCC and sold it together with the camera. I didn't keep it for the URSA. It's not, IMO, accommodating and a bit bulky. I'm also looking at the 502 combo... they are very nice but just cost almost the price of the BMD EVF so that can be a toss-up if I ever go that route. They're beyond my budget for an EVF too. I'm still trying to look for a practical and lower price point product without sacrificing quality. The Cineroid EVF is interesting too. I just don't know what the rez scale-down would do to the viewing image on the Cineroid when used with the URSA.
