The Sea & Sea YS-01 is a compact slave strobe that can be used for wide-angle or macro photography. With its circular beam angle of 100 x 100° and a guide number of up to 20 it is the perfect strobe for small Point & Shoot cameras or DSLRs. The DS-TTL (Digital Slave TTL) feature gives you automatic exposure control when shooting in slave mode. It is best to connect the strobe to the housing with a fiber optic cable. For finer lighting control it is best to shoot in manual mode. This is easy since the YS-01 has a ten-level power dial located on the back of the strobe.
The YS-01 is powered by 4-AA batteries. You can get up to 330 flashes at full power with NiMH batteries. With NiMH batteries you will get a blazing fast 1.9 second recycle time, so you will not miss all the action on the reef. The YS-01 has a bright 1W LED target light that is bright enough to use as a dive light on night dives.
An external flash is your most important accessory. The ocean is one big, blue filter. As you descend, the reds and oranges quickly become muted shades of blue and gray. Using a color corrected strobe light will bring back your subject's natural color. The included Sea Arm VII is constructed with fiberglass-reinforced plastic resin offering a lightweight yet strong arm. With the included components, you can create a custom arm setup for your lighting needs. The tray is included.
Also included is the Sea & Sea fiber optic L-type cable that connects the built-in sensor on a Sea & Sea strobe to the built-in flash on the camera. When the camera's internal flash fires the cable will fire the external flash. The L shaped connectors resist bending and have improved light conducting efficiency.
