An integrated TTL circuit is fine-tuned to the Olympus Stylus 1s flash exposure protocol for the most accurate exposure possible. The circuit is powered by the strobe for zero maintenance and no batteries to change. Exposure compensation in TTL mode is supported using the camera's built-in control. At this time, only Ikelite DS strobes are capable of powering the circuitry . SEA&SEA, INON, and Nikonos strobes will still enjoy fast recycle times and improved battery life, but must be used in manual exposure modes only.
This housing provides a direct electrical connection to the camera's external flash hot shoe. Cord attachment is as easy as screwing in a lightbulb, and the threaded fit prevents accidental detachment during use. The bulkhead connection has been moved to the top of the housing to keep cords out of your way and reduce strain on the cord ends. A variety of sync cord terminations are available for Ikelite, SEA&SEA, INON, or Nikonos strobes for ultimate versatility.
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. Use of a fiber optic connector requires the camera's built-in flash to fire, reducing battery life and bypassing the TTL functionality of the housing.
Two 1/4-20 threaded mounting points are included on the bottom of the housing for the attachment of a tray and handle system. Handles provide improved ergonomics underwater and are the foundation for your lighting mounts.
The port is threaded for the direct attachment of 67mm threaded accessory macro lenses. We recommend a macro lens which is designed for underwater use like those from Epoque, INON, Subsee, Nauticam, and other manufacturers. 67mm threaded wide angle wet lenses may be attached to the front of the lens port, but will exhibit vignetting (dark shadows around the edges of the image). Vignetting can be reduced by zooming in or cropping the photo in post-production
