Selling up all my camera gear as kids came along it’s not getting the use it should. This viewfinder I paired with an Mini URSA 4.6k Also Comparable with Blackmagic URSA Mini Pro 12K Blackmagic URSA Mini Pro 4.6K G2 & others that used the BNC and proprietary 4-pin XLR Perfect working order. Comes with two bolts to attach to camera
