Add the Ikelite INON UCL-165 M67 Close-Up Macro Wet Lens to the front of your underwater camera housing's flat port to get closer to your subject for beautiful high-magnification close-up photography. The lens can be used above and underwater, for both compact and DSLR/mirrorless cameras, and is usable throughout the zoom range, although some vignetting may appear at the widest-angle focal lengths. It is compatible with any port that features a 67mm thread on the front; the lens has a male thread on the housing side and a female thread on the front for stacking additional lenses. The lens consists of two elements in two groups and its optical glass bears an inner coating to suppress optical aberrations.
