The following is extracted from the manufacturer's website; please use it as a reference. Brand: Ulanzi Product Dimensions: 5.3 x 3.8 x 1.3 cm 【One-Touch Attachment and Detachment】The Ulanzi F38 quick release saves time when attaching and detaching equipment, which secondarily increases opportunities to utilize your shooting equipment. Attach and detach the camera with one touch; it locks automatically when you slide and insert the plate. You can quickly switch multiple cameras to the same equipment. Alternatively, you can quickly switch a camera to multiple pieces of equipment, which is very convenient and saves you time. 【Improved Secondary Lock Structure】Compared to the conventional lock method of pulling out the knob, the new structure can be locked twice by simply sliding it, making operation more convenient. The lock function reduces the problem of the button not pulling out well. The board automatically locks when you slide and insert it, and you can easily perform the second lock and unlock by sliding the side button. Especially in overhead shooting, the safety of the camera during shooting is increased. 【Wide Compatibility】There are 1/4'' screws *4 and 3/8'' screws *1 on the bottom of the quick release plate.
