I initially bought one like this hoping i could use it in place of the support arm. As it was shaped i hoped it would attach and let my camera slide in and out without having to remove my lens or undo the support.
Unfortunately again the seller did not accept returns so i couldn't send it back so i was a little unsure of what to do next.
I then purchased two of these below. The plan now is to remove and replace the entire Filmcity Cage unit with the Gini parts.
Although this has increased the cost of my rig i do think it will enhance it considerably.
Video to follow.
