This Fanatsea BigEye Accessory Dome M67 fits housings that have a 67mm filter thread on their port. The accessory dome corrects size distortion that makes everything appear 25% closer underwater. This allows you to get closer to large subjects.
By having less water between you and your subjects, your underwater photos will have more contrast and improved color saturation. The dome can be attached or removed underwater. It is perfect for shooting seascapes, divers, shipwrecks and schools of fish, without moving further away from the subject.
Note: Prior to purchase, confirm that no additional adapter is required to fit this dome to your housing.
