The Mid-range Focus Optimizer 3 (MFO-3) is a distinctive lens primarily designed to complement longer macro lenses such as the Nikon 105mm, Canon and Sony 100mm, and Sony 90mm. When utilized in conjunction with these lenses, it effectively expands the field of view to that of a 60mm lens. This focal length is particularly favored for capturing larger macro subjects and for black water diving. The MFO-3 offers the flexibility to be detached and reattached in water, providing the option to switch between a 100mm and 60mm focal length on a single dive. The MFO-3 can be securely mounted on a flip holder, bayonet, or threaded directly to the macro port using the provided adapter.
