Nauticam MFO-1 Mid-Range Focus Optimizer 1 M67 Macro Diopter Lens

Nauticam's newest Water Contact Optic, the Mid-range focus optimizer or MFO-1. The MFO-1's main function is to cancel the focus distance limitation of macro lenses underwater and provide ample focus distance for different sizes of subjects which were previously limited by using SMC-1 or CMC lenses. The MFO-1 also greatly improves optical performance by minimizing aberration.
