Comments about Acratech Acratech 6" (152 mm) Long Arca Style Quick Release Plate for Lenses.:
Really nicely made shoe. Fits perfect on my sigma 500 lens. Solid and really light. What I really like about these shoes made by acratech is that they are flat so you can leave them attached to the camera body or lens and they dont get in the way or make your camera unstable when you set is down.
