The Kraken Macro Lens +6 M67 Diopter 'Pro Series' produces tack-sharp results for your macro and supermacro applications. This lens is quite sharp and is much easier to shoot with than a stronger diopter. We recommend this lens for underwater photographers using a 100mm or 105mm macro lens, especially if you haven't used a wet diopter before.
