I received my Really Right Stuff Arca-Swiss compatible camera plate today. Excellent fit and looks, as typical for RRS gear. It adds about 3/8" of inch (9.5mm) of the height to the camera so is now very much like the HLD-6 landscape portion of the grip mounted on an EM-5. I was really surprised at the height difference of the EM-5 and landscape portion of the grip compared to the EM-1. For me it just made the camera fit better and easier to hold in my hands. So now I have that same feel with the EM-1. Since the Arca-Swiss style dovetail is wider than the EM-6 camera body there is a slight overhang yet provides a place for my pinky to rest. RRS chose to run the dovetail the entire length of the body so I can set down the camera and not have it tipping around. The plate has a strap boss at the right side end which my new Gariz leather XS-CHLSNLB neck strap now runs through, acting as a semi sling for me to carry. The RSS also has a center point marked on the back of the plate, so I know where the center axis of the lens is for mounting on the tripod and will help for panoramas.
