Designed for medium to large format cameras, the Sunway Foto DP-610R View Camera QR Plate allows you to quickly and easily mount and remove your gear from tripods and other support systems. The plate measures 4" long with a long 2.9" (74mm) center groove that is outfitted with both 1/4"-20 & 3/8"-16 mounts for the camera plus two safety stop screws that ensure your camera won't accidentally slide off your tripod. It is made from one piece of machined 6061-T651 aluminum, treated with a satin anodized finish, and features an integrated strap mount for fastening a strap or wrist lanyard to increase the comfort and security of the lens or the camera when you're carrying it.
