Nauticam’s Midrange Focus Optimizer (MFO-1) is a new underwater photography tool designed to improve macro lens performance. It helps reduce focus hunting, allowing for smoother focusing in challenging conditions. By enhancing image quality and extending the focus range, it offers more flexibility for capturing underwater subjects. The MFO-1 can increase magnification, achieving up to 1.6x when used with certain lenses, making it easier to capture detailed images of marine life.
