I'm trying to finalize my hardware/accessories package for Epic and wondered if anyone could answer the following questions. I couldn't find the info anywhere in the RED store.
What are the length and weight of the Arri Dovetail Mounting Plate (long)?
What are the length and weight of the Arri Dovetail Mounting Plate (short)?
If measuring each isn't handy, I'd appreciate just an opinion from those who've used both whether the short plate gives a reasonable amount of fore/aft travel to establish balance while maintaining complete contact with the dovetail receiver in the x Bridgeplate or similar baseplate. I plan to buy 3 dovetails, leaving one each on tripod head, crane head, and something like the Sumo 1 handheld rig from Shape. Besides the great price at B&H ($403.92), the Shape system has attracted me because it offers what looks to be a well padded, well-rounded shoulder pad with a back pad for mounting battery plate and/or additional accessories to really help with balance AND it has handles onboard (which impressively can be adjusted with one hand via a pushbutton on the side, although I'd much prefer if they had extensions.) So my idea is to have a lean, compact setup when the camera is anywhere but on the shoulder, mounting the V-Mount battery plate to the back of the camera via x's Quick back system, and then be able to simply slide the camera quickly of the tripod or other mount, slide it onto the Shape system, quick release the Quick Back/battery plate/battery from the camera and mount it to the back pad of the Shape. For the latter, the back pad would have permanently attached to it something like http://the View Factor Shuttle Mount. This setup would consolidate handles, shoulder pad, and displaced battery mount on one rig so that no weight is added for all other scenarios where those items won't be needed or used.
My instincts tell me that the longer dovetail plate would work best on the shoulder rig to afford greatest play for balancing, but I'm not sure whether I should use the long plate for all applications, including tripod, and I don't know what my weight tradeoff will be. The longest/heaviest lens I plan to use with any regularity is a Canon 70-200, sometimes with a doubler, and a clip-on 2-stage 4x6 Petroff mattebox on the front of that. I offer that if it helps in gauging whether the long or short plate would work best for me.
Much thanks in advance to all who reply. ETA: The title of this thread should have included "Arri" instead of "Arris".:-0
