The Manfrotto 200PLARCH-14 Architectural Quick Release Plate finally provides a solution to the tired problem of unwanted movement between gear and quick release plate. This plate, which works with the Manfrotto RC2 Quick Release, features a metal lip which can be positioned in front or in back of the camera/tripod collar to eliminate rotation. Especially ideal for vertical shooting.
When I explained to the Tripod Guy that I was worried about my Canon 5D Mark IV and 11-24mm heavy lens slipping off the tripod when I went from horizontal to vertical shooting he said, no problem and produced this little metal plate. I balked at the price, but that was stupid: this has changed my photographic shooting life because I NO LONGER FEAR SLIPPAGE when I got from one direction to another. It holds and protects the camera like a parent to a child and I can even leave the camera alone on the tripod for longer exposures without worrying about slow dips as gravity does her thing. Get This. Don't think about the price, just get it.
Works perfectly at keeping the camera stable and in place. However, between ordering it and receiving it, I switched to Gitzo tripods so...it looks nice sitting in my drawer.
