This is a clever follow-focus / manual zoom lever for DSLRs and pro video cameras. It will fit virtually any lens, including those with narrow zoom or focus rings on the lens barrel. This is an easy way to get whip zooms or selective-focus effects. The lever is a high-quality component made from copper, zinc, and silver. It will not bend or break. The part that touches the lens is plastic, and it won't scratch or damage your lens. It attaches with common zip ties / cable ties...there are no proprietary parts to replace later. I'll include 5 ties with the lever. It has an anodized blue knob. I'll ship anywhere in the lower 48 states for $2.00 (additional levers will be shipped for FREE). Payment must be received within 7 days.
