This Fantasea BigEye Accessory Wide-Angle Lens M46 fits housings that have a 46mm filter thread on their port. It 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 lens 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 lens to your housing.
