This is a well made part, however it does allow the Canon MIII to shift position in the mounting plate. Also it would have been good to include an attachment pin so that cameras could easily be changed into the bracket.
I deal with PMG because they do offer HIGH QUALITY gear that fits precisely and tight. They are also LOCAL to Chicago and I believe in support of my local businesses. The other cool thing, regarding things like their base plates is they work modular with other pieces of equipment they make. So, the base plate for your camera, attaches to their Boomerang Flash Bracket and not from the Arca Clamp. It's modular, so it's low-profile and light weight. Good stuff
This is a very well-made solid bracket. I'm using it on my pro Canon 1Ds Mark III.
The plate is a perfect fit, and I'm glad I purchased it. If there would be a 'Con' it would be it doesn't release quickly from the bracket.
I bought this product to work with my Flash Bracket boomerang and the product works fine but there is no instruction and it's hard to obtain production support/information. It's difficult to understand what is needed and what isn't.
