A high-magnification close-up (macro) wet lens providing approximately +6 diopters (165mm) of magnification to reduce the minimum focus distance for macro photography. It uses 2 elements in 2 groups of high quality optical glass with an inner coating to reduce optical aberrations. The lens has a male 67mm mounting thread plus a female 67mm front thread that allows stacking of additional lenses. It works above and underwater throughout the zoom range, though vignetting can occur at wide angles. Approx. 2.8 in diameter.
