When adding a Shoulder Pad to your Camera Rig, you'll often want this to be placed the best possible balanced position. But if you're also trying to add a QR plate to your rig so you can quickly throw it onto a Tripod, this also needs to be in the same placement as your shoulder pad. To solve this dilemma, Cool-Lux has designed a folding Shoulder Rig base called the Shift Baseplate.
At $975, it's a pretty expensive piece of kit, but if you're serious about getting good balance with your Rig both on the shoulder and while on a set of sticks, there's not a whole lot of other similar equipment options. The Cool-Lux Shift Baseplate is available now, check it out over at the Shift Baseplate product page (here).
Just a quick intro on the Cool-Lux Lux Gears. These can be added over the focus ring if you're working with non-cine lenses and have to use a follow focus system. It's a flexible material that is still firm enough to where it won't slip under your FF. They make a variety of sizes so that they can fit perfectly with your lens.
Earlier I posted about how you can use a rotating flash bracket to add an extra hotshoe to your camera. The rotating flash bracket is nice, because it acts like somewhat of a half DSLR cage, but here's another option. This dual bracket mounts to the top of your Canon EOS 5D Mark II or Canon 7D. Not sure if I would put this type of weight onto a 550D / T2i, but that's your decision. Available through the links below.
