The 6147 housing for the Canon G7 includes special conversion circuitry to utilize the Canon eTTL system with any current model DS SubStrobe, providing total compatibility as the DS SubStrobes emulate a proper Canon strobe. See strobe requirements by serial number .

The housing includes a diffuser to allow photos to be taken with the built-in strobe of the camera.

The Release Handle and Tray included allow easy attachment and removal of optional SubStrobe mounting arms at the touch of a button.
Housing measures 7" wide (10" wide with the removable handle bar attached), 6" high, and 6" deep. It is molded of corrosion free clear polycarbonate and operates to 200 feet (60m).
Every camera function except the self timer and continuous button is accessible in this very sophisticated housing installation. Complete housing and camera weighs less than 6 pounds.

Optional Inon UWL-100, Epoque, and the #6420 Ikelite wide angle lenses attach directly to the port, but extreme lens length precludes any advantage.

SPECIAL #9305.92 Optional Flat Port slightly limits camera's zoom range, but allows for effective use of 67mm threaded external wide-angle lenses

An optional #6441.41 UR Pro removable color correcting filter for use without flash is available.
Non-Ikelite strobes can be used operating as manual strobes, but not with the EV Manual Controller. They will require a special sync cord . The Ikelite DS-51 SubStrobe offers the best of everything from its compact size to providing eTTL or six manual powers by rotating a single knob on the strobe.
The Ikelite DS-125 SubStrobe provides TTL and choice of full, 1/2, 1/4, & 1/8th manual powers.
