CANON BNC LENS FD 300mm 1:2.8 L SUPER FAST CAMERA LENS KIT BROAD CAST CASE XTRAS. The lens is supplied as a complete kit with all the accessories visible in the pictures that include, filters, lens cap, aluminium flight case, tripod mounts and rails. I believe this lens to have a BNC lens mount making this a conversion suitable for broadcast quality, but I am open to correction. The lens is used as can be seen from the cosmetic condition in the images. Th glass is in good condition. Mechanically the lens is in excellent working order.
