The SharpEye Lens M67 +8 from Fantasea Line is an accessory macro lens with a +8 diopter that fits over an underwater camera housing's lens port. It can be installed and removed during the course of the dive. The lens is great for shooting close-up images of fish, coral, textures, and more. It magnifies the subject and enables the camera to focus at short distances, allowing for very sharp images. The lens has a 67mm thread diameter for mounting onto ports with matching threads and can also be attached to ports with smaller or larger threads by using optional adapters.
