Product Information
The Fantasea SharpEye Lens M67 +8 (Cat. No. 5123) is an accessory macro diopter lens that threads onto the outside of an underwater camera housing's lens port to magnify close subjects and let the camera focus at much shorter distances. It has a 67mm thread mount, a +8 diopter rating, and a 200 foot depth rating. It can be attached or removed between dives or even during the course of a dive.
Who it is for
This lens is built for underwater photographers who want sharper close-up and macro shots of fish, coral, and fine textures without switching camera lenses mid-dive. Because it mounts externally on the housing port rather than inside the housing, divers can add or remove it between subjects, making it a practical choice for shooters who split a dive between wide-angle and macro opportunities.

Frequently Asked Questions
Can I change the SharpEye +8 lens underwater during a dive?
Yes. The Fantasea SharpEye M67 +8 is designed to be installed or removed from the housing port while diving, so you can switch between normal shooting and close-up macro shots without surfacing or opening the housing.
Will the Fantasea M67 +8 lens fit my housing port if it is not 67mm?
The lens has a 67mm thread mount and can be attached to ports with smaller or larger threads using optional adapters.
How deep can the Fantasea SharpEye M67 +8 lens be used?
The lens carries a depth rating of 200 feet, so it can be used on housing ports with matching threads within that depth.
What does the +8 diopter rating mean for macro shooting?
The +8 diopter magnifies the subject and lets the camera focus at short distances for sharper close-up images.
