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. Extension can be used with the Nikon 105mm VR Macro lens and either 5510.16 or 5510.22 Lens Extensions. Canon 100mm USM lenses require the 5510.16 Lens Extension.

The Focus Extension can be used in place of Lens Spacer 1.75 in in most instances. The Focus Extension should not be used with the bayonet-style lens extensions 5510.10 or 5510.11.

When used underwater, flat ports bend light in such a way that the resulting image is magnified. This makes flat ports ideal for shooting small subjects with a standard, macro or zoom lens.

The Modular Glass Flat Front features a durable, optical grade glass front element. Lens Extensions are available in a variety of lengths to accommodate most popular portrait and macro lenses. The Modular Glass Flat Front does not attach directly to a housing. A compatible Lens Extension is required. Each Lens Extension simply threads into the base of the Modular Glass Flat Front. A strap wrench is included for easy removal.

Note that if a port is long enough to accommodate the full length of a 1:1 macro lens, the lens may vignette at infinity when used behind a flat port. A flat port reduces the angle of coverage of a lens when used underwater. If you're shooting a wide angle or super-wide angle lens, we recommend using the Modular 8-inch Dome instead to preserve the full angle of coverage of the lens.
