Description
Versatile macro diopter — powerful enough for serious macro work, forgiving enough for beginner macro photographers.
The KRL-05S “Lucky #13” is a +13 diopter macro wet lens that hits the sweet spot for most underwater macro photographers. At +13 diopter, you get dramatically increased working magnification over a standard macro lens, while maintaining slightly more working distance than the more extreme +23 diopter option — giving you more time to compose, focus, and shoot before a subject moves out of frame.
The M67 thread mounts directly to any 67mm wet lens port or via adapter. Nicknamed “Lucky #13” because once you shoot with it, you’ll understand why macro photographers don’t leave the surface without a close-up diopter.
