I just made the move to all arca and am buying extra plates to leave on my cameras.
In case anyone happens to know... RRS used to make a plate specifically for the Canon 70D, model B70D. It seems to have been discontinued. Anyone have any idea if the new model for the 80D would work on the 70D. The style looks different enough that I am afraid it might not, though it seems it still works with the BG‑E14 grip so maybe?
My wife is using my 70D but she hates grips so I have a Canon BG-E14 grip and the Kirk one piece L bracket sitting around.
