Sea&Sea YS-55 TTL/E
€ 299.00

The YS-55TTL/E is the first E-TTL compatible YS-series strobe designed for both Canon digital SLR cameras and compact digital cameras. E-TTL photographyÅñ (available on Canon digital SLR cameras) allows electronic through-the-lens flash metering in digital photography, automatically providing just the right amount of light for perfect subject exposure. When the YS-55TTL/E is connected to a Canon E-TTL compatible camera in a SEA&SEA housing using the Sync Cord GN, the strobe's slave function is deactivated to enable E-TTL by depressing the camera shutter. E-TTL eliminates hit-or-miss manual adjustments to strobe power for proper exposure. The YS-55TTL/E is a compact and highly mobile strobe. You can easily configure it for just the lighting angles you need. To conserve power, the YS-55TTL/E comes with energy-saving auto-power-off circuitry that shuts off power if the strobe is not used for seven minutes. To prevent gas build-up in the strobe, it comes with a SEA&SEA standard over-pressure release valve that releases any excess gas generated through operation. The YS-55TTL/E has a fiber optic cable connector and a 6-step guide number controller that can be used with compact digital cameras that don't have E-TTL. The strobe's built-in pre-flash controller makes it compatible with most compact digital cameras on the market. This versatile strobe is a superb companion for simple compact digitals as well as fully professional digital SLRs. Use its enhanced features to bring home images cast in a perfect light.
