The LB450 from Benro is an Arca-type lens support bracket designed for use with telephoto lenses up to 500mm. The bracket features a solid aluminum construction with a built-in bubble level and can support up to 61.7 lb.
The bracket utilizes a sliding Arca-type clamp which adjusts along the main bar to accommodate lenses of different body lengths. A height adjustable forward support uses two rotating discs which allow the lens to be held steadily without hindering the use of the focus, zoom, or rotation collars. All components of the bracket use an Arca-type dovetail which is compatible with most Arca systems. An Arca-type lens plate or collar is not provided with the bracket and is required for use.
