3 Legged Thing QR4 Quick Release Plate 38 x 38 mm (QR4-EQ)

These are excellent quality and obviously fit my Three Legged Thing AirHed perfectly.But I bought them as a slightly cheaper alternative to the Peak Design plate as they claimed to be Pro-Capture compatible.Sadly they’re not totally compatible: there are two Allen-key machine screws on the base which help with locating the plate on the Three Legged Thing AirHed. But they totally prevent the plate from being used on the Peak Design Pro-Capture clip unless they are removed. No suitably-sized Allen key is provided for that.Also, unlike the Peak Design plate, the 3LT version can only engage with the PD Pro-Cap in a single axis only, unlike the PD item which engages in both the X or Y axis. So with the 3LT version you need to make sure that you attach the plate to your lens or camera the correct way around, unlike with the PD version.The machine screws act as safety pins on the 3LT AirHed so give a bit more security.So if you’re not going to buy a Peak Design Pro-Capture, then these 3LT plates are a superior design. But if you are going to use the Pro-Cap then these are inferior.I’ve knocked one star off as the product is not fully Pro-Capture compatible without modification and fails to make that clear and fails to include the necessary Allen key to remove the screws.Since writing the above review I’ve discovered another minor incompatibility: this plate is about a hair’s breadth narrower in all directions than the PD plate. What that means is if I adjust my AirHead Switch (the one with the lever) to grip my PD plates then it fails to grip these 3LT plates at all. And as I’ve had to remove the safety screws from the bottom of the 3LT for PD Pro Cap compatibility that’s a real problem. If I adjust the AirHed to grip the 3LT plate then the locking lever becomes almost impossibly tight to operate when I use a PD plate. Also the 3LT plate is a much sloppier fit in the PD Capture clip (and is non-adjustable).So you need to choose to standardise with just one clip system: if you’re not going to use PD Capture plates, and only use 3LTs AirHeds then these 3LT QR4 plates complete with their safety screws, may be the best choice for you. But if you’re going to use the PD Capture or intend to use any other ARCA-Swiss compatible heads, then stick to the PD plates.One other point against these plates for me is that the PD version has a mounting screw fitted into a slot, so that I can adjust the position of my plate. This 3LT version does not; and on my OM-D E-M1 mk ii the tripod hole is quite far to the rear of the camera baseplate. That means a lot of the surface contact area of this 3LT plate is not used, but with the PD plate I can slide it forwards on the adjustment slot before final tightening so that the entire surface area is against my camera baseplate.

This is perfect! I now have 3 3 legged tripod attachments and all of them are superb.It might seem like a lot of money but this should last for ever. Attaching with an Allen key ensures it never comes loose.

One came with the tripod but easier to add them permanently to devices you would use on it.Well made and feel very secure.

A gift that was received well,very neat was the feedback
