Just wondering if anyone has any suggestions as to where I can purchase an L plate that would fit my Canon 40D.
Really Right Stuff sells them but, cost wise, it's more than I want to spend if not necessary.
I'm using a Manfrotto tripod/head system so, if I was to get the RRS L plate, I then either have to buy a RRS clamp and a reducer bushing to make things fit on the Manfrotto ballhead or, one of their ballheads and matching clamp.
