[When using UFL-M150 ZM80]
*The UFL-M150 ZM80 is a special conversion lens to capture a small subject in entire image when shooting at very close range to obtain so-called "insect eye lens imaging". Its optical design makes lens diameter relatively small and provides minimum aberrations when shooting a subject just in front of the lens. So if you shoot whole underwater landscape with focusing to infinity as like using ordinary fish-eye lens, it may not produce intended result.

*This product is designed for underwater use only. Not usable on land. Use a tank or bathtub filled with water when conducting test shot on land.

*When shooting, zoom towards to telephoto side at approximately focal length 80mm (35mm film equivalent) until no vignetting is observed. Shooting at wide end setting will give you a circular fisheye image (view angle 150 degrees).

*Since the lens has small diameter and enables to focus at 0cm from the lens surface, depth of field gets enormously shallow when shooting in few mm distance. In such a case, it is recommended to use small aperture setting.

*This product is not compatible with any of INON "Lens Holder" due to product feature to adjust mount position back and forth by screwing it.

*The built-in flash light could be blocked depending on housing, shooting distance or angle of view etc.

*Be well conscious of marine environment and marine lives not to stress and harm them when shooting with this product.
