Ikelite Focus Extension for Modular Ports

A special extension is available for use with Nikon 105mm VR Macro and Canon 100mm USM Macro lenses. Manual focus is adjusted with a large, easy-to-turn knob on the side of the extension. For use with either #5510.16 or #5510.22 Port Bodies.

Unlike the standard focus ports for these lenses, this combination allows the user to alternate between manual and auto focus while the camera is installed in the housing.

The Focus Extension can be used in place of the 1.75" Standard Extension in most instances. Note: The Focus Extension should not be used with the bayonet-style #5510.10 Super-Wide Angle Port Body.

Port Extensions can be added to any Port Body and Modular Dome or Modular Flat Assembly combination to extend the overall length of the port.

Extension length is added to overall lens length accommodated by a given port combination. Lens length is measured as the maximum extended length from attachment point on the camera body. Maximum lens diameter is limited to 8.4cm (3.3").
