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.SeaLife's large External Flash unit provides additional light for brighter underwater pictures with more vivid colors. SeaLife's External Flash is positioned 12 inches away from the camera's lens, and a deflector covers the camera's 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. The lens slips onto the camera for close-up photos within 2 to 4 feet underwater and 10 inches on land. For distances over 4 feet, simply slip the lens off, even when underwater. The multi-coated lens enhances red and yellow color and reduces excessive blue color while providing exceptional clarity. The lens coating also reduces the possible over exposure of the ReefMaster cameras' built-in flash at close distances.
