I often use my Q2 on a tripod in combination with a Sirui mounting system. I also have the original handgrip mounted on my Q2. To securely mount the Q2 on the bullhead of my tripod I use the small Sirui TY-C10 plate. This makes a quick and secure mounting/demounting of the Q2 on the tripod possible. The problem is that the plate blocks the big screw of the handgrip. I have to demount the plate to be able to reach the battery and/or memory card compartments. In my view this is simply a design weakness. (Another designers weakness is that the screw-hole in the handgrip is not central to the lens (as it in on the camerabody). I have to use several accessories to correctly mount the camera in central position on the tripod).
To make the access of the compartments easier I have cut a small piece of thin (sheep)leather (0,2-0,4 mm) and put it under the plate. Now the Sirui plate fits solid on the camera body and the screw of the handgrip can be used without each time having to demount the Sirui plate.
