An included flash diffuser improves lighting quality when the camera's built-in flash is used. A built-in flash is effective between 1-3 feet (0.3-0.9m) from the subject in clear conditions. For best results a color correcting filter or external lighting is recommended. External lighting is more powerful than the camera's flash and can be placed in a position to virtually eliminate the backscatter - or "snow" - from your underwater images.

The optional AF35 strobe triggers and provides automatic TTL exposure by watching the camera's built-in flash, without the need of fiber optic cords or sensors. Alternatively, two ports are provided for the connection of up to two Ikelite-, SEA&SEA-, or Olympus-type fiber optic cords.

The housing port is designed to accept color filter, wide angle, and macro options for 3.9-inch diameter ports. Light is absorbed very quickly as it passes through water. A subject will look darker, less colorful and somewhat grainy when viewed through even a few feet of water. The addition of a compatible wide angle accessory expands the camera's field of view underwater, providing the opportunity to get as close as possible to the subject and reduce the amount of water light passes through. The results speak for themselves - photos with the best color, exposure and clarity possible.
