I have a Sirui PH-20 tripod head that I use for my Canon 500mm lens. I use the plates that came with the head, but last time in Yellowstone, a photographer had an extended plate that gave his lens more stablilty by having a longer surface area. Lucky him..his friend had made it for him.
Any ideas on where I would get a longer plate. Have not seen any on the obvious sites. Thank you.
