Review on Versatile Camera Base Plate with 15mm Rod Rail Clamp for Enhanced DSLR Rig Support System by Melvin Goerge

I mounted this on my F55 to have 15mm rails to the matte box in front and I could put the 501 plate on the bottom to attach to my shoulder pad or them put on a tripod. I really like this system because it allows me to store the matte box and other accessories with the camera without having to disassemble the setup to go from a shoulder to a tripod or slider or whatever.
