The Inon UCL-67 M67 underwater close-up lens is designed to deliver high magnification yet superior image quality best suited to full frame SLR macro lenses of focal length 60mm - 100mm with comfortable long working distance enabling easy lighting. The lens also supports mirrorless as well as compact system.
This close up lens is for underwater use only, +15 diopter, yet has a working distance of 52mm when used with 105mm camera lens.
This lens mounts on ports with 67mm threads. The lens is also available as an LD mount version.
An optional adaptor is available from Inon which permits mounting this close-up lens on flip lens holders from Nauticam and others. The mounting ring supplied with this lens is removed, and the Inon M67 Flip Mount Adaptor for UCL-67 is installed in it's place.
