Mid-range Focus Optimizer 3 (MFO-3)
Nauticam once again demonstrates its commitment to underwater photographers with the introduction of the Mid-range Focus Optimizer 3 (MFO-3). As full-frame mirrorless cameras become the go-to choice for serious underwater imaging, a key limitation has emerged: the lack of close-focusing, wide-angle macro lens options—especially for blackwater photography. The MFO-3 is designed to solve that problem without requiring new camera lenses or ports.
