This port features a longer base which is required with certain very large diameter zoom lenses including the Canon EF 11-24mm lens. Refer to the DL System Port Chart for compatibility.
External filters are not compatible with dome ports. Look for filters that attach to your lens prior to installation. We recommend Magic Filters (not sold by Ikelite).
This port can be attached directly to housings featuring the Dry Lock (DL) port system or combined with DL extensions.
