The Kraken Macro Lens +13 M67 Diopter "Lucky 13" produces tack-sharp macro images with maximum magnification of 2.5x (area ratio x 6.3) with a 105mm f/2.8 lens and focusing range of 60mm-85mm. The lens is also known as "Lucky 13", with a +13 diopter with 4 elements, 3 groups, and up to 2.5X magnification. It can be attached to 67mm threaded lens ports on underwater camera housings. This diopter contains four broadband anti-reflection coated elements arranged in three groups, allowing for clear images with corner-to-corner sharpness. Built for durability, the lens barrel is made of Type II anodized aluminum. This is suitable for your macro and super-macro needs. More magnification can oftentimes be better, and the new +13 rates higher than most of the existing diopters on the market.
