Conceptually, I wanted to know, whether rotating QR Platform(as in the case of RSS Pano clamp) is same as rotating ballhead system itself(as in the case of Acratech Ultima ballhead..).
You answered my question in
"....since the rotation mechanism is on the top of the head, it can be leveled with the ball head lock and will rotate while maintaining the level. the Acratech head allows you to use standard tripod screw thread attachment to your camera. the rotating base is at the bottom of the head and will rotate about the axis of the tripod mount. in general, this will not be level unless you level the entire tripod......"
I understand that I need L bracket, body plate, MPR rail, RSS pano head, Arca style QR platform..
Thank you verymuch Ramesh
they are for different purposes. the RRS clamp replaces the camera attachment on your existing ballhead and changes you over to the Arca-Swiss style QR system. since the rotation mechanism is on the top of the head, it can be leveled with the ball head lock and will rotate while maintaining the level. the Acratech head allows you to use standard tripod screw thread attachment to your camera. the rotating base is at the bottom of the head and will rotate about the axis of the tripod mount. in general, this will not be level unless you level the entire tripod. depending on the type of tripod you have, this may be easy or hard. 5 or 10 degrees inaccuracy is not going to make a difference in a panorama stitching program.. you usually need to overlap 30-50% to get good results. if you read further on the RRS site on creating panoramas, or on other sites such as Panoramic.net or panoguide.com, you will see that you need a ballhead with a rotating base and a panoramic rotator in addition. attaching the RRS pano clamp permanently to the Acratech head, if that is the one you like, is what will work best. you will still need an L-bracket system, and ideally, you will want one with fore-aft movement too so that you can set the nodal point, which an L-Bracket on a panorama clamp will not let you do.

you would think so but it doesn't. it's how they do market research to see if there is enough demand for the lesser volume cameras to justify them making a plate. they made one for my Nikon Coolpix 5000, but they are not making any for the Coolpix 8400. i have to use a generic plate that is bigger than it needs to be by a lot.

Even when placing online order for Universal L bracket, we are supposed to mention specific camera model. It means they may be having something specific to *itsD.
