The A-HG74 is a hand grip support option, providing three cushioned hand grips for the A-CA74E adaptor base & camcorder. There are two hand grips at the front while the third handle at the rear provides support to the chest area to add extra stability. The angle of each hand grip can be fully adjusted & locked in position as required. Using the A-HG74 hand grip supporter with the A-CA74E enables smoother & more precise operation of the system, minimising vibrations & unwanted camera movement. It can also significantly reduce the weight strain placed on the operator's arm & wrist area which can occur when using just the camcorder palm strap. The hand grip supporter also has an integrated tripod adaptor base for attaching the complete system to a tripod plate. When the A-CA74E is used without the hand grip supporter, the tripod adaptor (model M-TR74) can still be utilised & is available separately.
