    • Clamps adapters

    Clamp adapters hold a lens or other cylindrical part by gripping its outer surface.

    Browse by clamping diameter

    Choose the outside diameter of the part to be held. Check the individual product for its clamping range and the connection on the other side.

    Browse size ranges

    Use the Front Side and Rear Side filters in the product listing to narrow down both connections.

    Clamps: selection guide

    Choosing a clamp

    Measure the outside diameter at the point where the clamp will sit. Check that there is enough straight surface for the clamp and that screws will not press on moving parts.

    Tightening and support

    Tighten the screws only enough to hold the lens securely. Overtightening can damage the barrel, jam its mechanism or damage optical elements. A friction connection can slip; support heavy lenses and check the grip before use.
