Neewer Telephoto Lens Bracket chemistry type_Developer as you might have deducedIt looks like it's made out of leftover tripod parts, and it kind of is, but the Neewer telephoto lens bracket is a sturdy, all metal system designed to balance a camera and lens on a single long Arca plate. The camera bracket is adjustable back and forth, and the lens support can be moved up and down. In addition to the bubble level knobs that you can see in the pic, the 20cm baseplate has an inset bubble level, too. In excellent condition.
