The Cavision Lens Support with Metal Lens Fastener bears a portion of the weight of a large DSLR lens or a mini 35mm lens adapter and keeps the lens stable as you pull focus. The device can also provide support for wide-angle or telephoto attachment lenses. The Lens Support is designed for use with standard 15mm rods systems with 6 cm spacing.
The internal diameter of the lens-fastening ring is 85mm, and the ring attaches to the lens via adjustable screws. (Cavision ARP3 series step-down rings are available for smaller lenses – not included.) The height is adjustable.
