This Smartphone Mounting Kit from Smith-Victor supports smartphone devices within a clamp that opens between 2-4" wide, and it's adjustable to hold the device in a vertical or horizontal orientation. Moreover, the cold shoe mount on the bottom of the ball head slides into both the 13.5 or 19" Smith Victor LED ring lights, which provide very pleasing portraits when used in conjunction with the Smartphone Mounting Kit and your smartphone. Additionally, there is also a 1/4"-20 female thread on the bottom of the ball head if you wish to mount it to a tripod.
The mounting clamp is removable from the ball head, which reveals a 1/4"-20 male stud. The ball head, which has a weight capacity of 6 lb, accepts mirrorless or DSLR cameras. The ball head has a single release lever that controls both the panning and the ball of the head.
