The VP-350 Telephoto Lens Support Quick Release Plate from Sirui enables you to mount a camera with a telephoto lens on a Manfrotto quick-release equipped tripod. The camera attaches to the standard 1/4"-20 mount Arca-type quick release on the upright support while the foot of the telephoto lens attaches to the horizontal bed via its 3/8"-16 and 1/4"-20 mounting studs. With three mounting points, plus a rubberized non-slip surface, the chances of unwanted camera movement are reduced significantly. To aid in lens alignment there is a spring-loaded alignment pin incorporated into the lens plate.
The locking camera support can slide up or down to adjust to specific camera models. You can then use the incorporated bubble level to ensure perfect balance. If the shooter wishes to work in portrait mode the standard release plate can be replaced with an optional 'L' bracket.
