The Nauticam Mid-range focus optimizer 3 or MFO-3'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-3 also greatly improves optical performance by minimising aberration. Compared to the MFO-1 the new MFO-3 offers an even greater working distance although the maximum magnification is reduced.
