The first step in shooting impressive underwater images is to get close to a subject. If you shoot distant subject, you may get bluish or whity blurred image because of the amount of water between the lens and subject. It is essential to use a wide conversion lens to shoot wider at close distance.


A wider lens enables you to shoot • • • • •
• wider underwater landscape
• group photo with more divers in clear image
• bigger subject like manta in single image
• bigger subject clearly for closer shooting distance

[When using a wide conversion lens]

*When shooting without an external strobe, it is recommended to use ambient light only instead firing the built-in flash since the built-in flash light may be blocked depending on a housing design, shooting distance or angle of view etc.
It is recommended to use compatible external strobe (Z-240, D-2000, S-2000 etc.) connected via "Clear Photo System".

*Set the camera to wide end. If you observe vignetting at wide end, zoom to telephoto side minimum necessary or crop the image after taking image. The lens is designed to get optimum performance at above setting.
