The HDLA-3501 allows operation of the HDC cameras together with large studio/OB lenses and viewfinders. It provides a very simple one-touch cable-free mounting of the camera head so that it can be quickly and easily converted from hand-held to tripod configuration. This is an affordable and lighter model with its simple features while allowing you to utilize the rear panel operations on the combined camera head by the wider open area of HDLA-3501 mechanical exterior design.
