In essence, the are very simple. They are long quick release plates that can be mounted in an Arca-Swiss-type tripod head (including 3 Legged Thing’s) instead of a standard plate. Their extra length and additional fixing points mean that you can mount things such as lights, microphones, monitors or scopes onto the plate, as well as your camera. 3 Legged Thing makes the Ultra Plates in , 150mm, 200mm, 250mm and 300mm. They’re constructed from anodised aerospace-grade and the shortest one weights 81g while the longest is still only 143g. They all feel very strong and I’m unable to bend any of them, even the longest, when using my full strength. Each plate has a that runs for most of its length, enabling precise positioning of whatever camera kit you’re mounting. This positioning can be guided by the measuring marks on each long side of the plates. Helpfully, the zero point is at the centre of the slot, which makes it easier to ensure that weight is evenly distributed for better balance. 3 Legged Thing supplies the 250mm and 300mm plates with two 1/4”-20 stainless steel in the slot, while the 150mm and 200mm plates have just one. But it’s possible to add additional screws or remove the existing ones if you want. Either side of the screw slot, each plate has a series of for mounting accessories. These can be mounted directly or via an arm. There’s also a at one end of the plates, which could be useful for holding a flash, or anything else with an appropriate mount. This shoe has a 3/8”-16 thread at its centre, adding to the mounting point options. Next to the cold shoe, there’s a , which is useful for keeping cables neatly to one side of the camera. That’s especially helpful for videographers who may have a bunch of cables protruding from their camera, but it could prove handy for flash cables too. At the opposite end of the plate, there’s an ‘ ’, which enables it to be mounted at 90° to the standard position. I found it’s possible to mount the plates securely, but I’d be inclined to remove the small security screw in the bottom of the plate so it sits properly in the tripod head. 3 Legged Thing has also introduced the (£50/$54.99), which connects with an Ultra Plate to create a more stable
shooting platform when using a long lens with a tripod foot. It connects to a plate via the 3/8”-16 thread and has an angle adjuster that enables it to be mounted onto the base of a camera. 3 Legged Thing’s Ultra Plates are more versatile than the average long quick release plate. They’re also extremely well made with a very durable build, lots of mounting options and rubber pads to help keep everything in position.
