Light is absorbed as it travels through even short distances underwater, making colors appear dull or monochromatic. To preserve the natural colors of your subject, it's important to stay within arm's reach—no more than 3-4 feet (1m) away. For the best results, we recommend adding an external flash or high-powered constant-on light if you'll be diving regularly below 15' (3m).
This housing supports your choice of shooting strobes by electrical sync cord or fiber optic triggering.
You can enjoy the fastest and most accurate TTL exposure on the market by adding the DL2 DS Link Sony TTL Converter Ikelite ST1 Hotshoe and B1A Bulkhead Kit # 46045 and a compatible Ikelite DS strobe. Exposure compensation may be used added or subtracted in the camera. Reliable locking connectors between the hotshoe and bulkhead make it easy to install the optional TTL electronics or carry back up parts when traveling.
The camera's built-in flash is suitable for firing an external strobe, but not for lighting a photo underwater. Two fiber optic ports are built into the front of the housing provide an attachment point for fiber optic cords from most major manufacturers.
A bright constant-on video light can be used instead of or in addition to a flash. A constant-on light is not as bright as a strobe flash. Constant-on lights do provide added versatility because they can be used for focus assist and for improved colors when shooting video.
There is a simple rule that brighter is better underwater. A high-quality lighting system can produce professional quality results.
Fiber optic slave flash units require the camera's flash to fire every time. This creates a shutter lag as you wait for the camera's flash to recycle in between shots, drains your camera's battery life, and builds up heat inside of the housing. Ikelite electronics translate direct electrical impulses from your camera, triggering your strobe and precisely adjusting its power without the need to fire the camera's flash. This eliminates the slave TTL strobe issues of signal interference, inconsistent exposure due to weak fiber optic transmission and false triggering caused by light rays bouncing off the water's surface or your buddy's flash going off.
