The SL560 Pro Dive Camera Set includes everything a diver needs to professionally document underwater adventures. This kit will have underwater photographers of all skill levels shooting like pros. Operational up to 164 ft, the 35mm Reefmaster RC camera features a wide angle lens, big sports viewfinder, large shutter lever (for easy use with gloves) and automatic winding. It's also equipped with a special built-in "coral flash" that compensates for the blue effect on closer objects but leaves the aqua blue color of the water untouched. SeaLifes large External Flash unit provides additional light for brighter underwater pictures with more vivid colors. SeaLifes External Flash is positioned 12 inches away from the cameras lens, and a deflector covers the cameras built-in flash, to reduce annoying backscatter -- small particles in the water that reflect light and cause white spots to appear in the picture. The unit allows divers to aim the flash at most any angle. The flash unit can function reliably at distances from two to eight feet from the subject. The Macro 3x Close Up Lens is easy to attach.
