Everybody can enjoy TTL strobe photography with this affordable, easy to use, compact underwater strobe.
Circular beam angle of 100°x 100° and guide number of up to 20. The YS-03 is a compact-type slave strobe that can be used for all applications from wide-angle to macro photography.
Easy and Versatile Slave TTL
As the YS-03 has been designed to mimic the light intensity of the camera's built-in flash, it is not necessary to manually adjust output. The YS-03 is compatible with any camera with a pre-flash and that has a TTL flash exposure function, regardless of make.
Comes with diffuser as standard
The half-translucent section diffuses and softens the light from the strobe. Using the diffuser gives softer, more evenly exposed images. The diffuser will also help reduce effects of overexposed images or when strong light produces shade/shadow in the image.
The YS-03 has been designed for any underwater photographer to use and is easy to understand. The only control is the rotary power switch and by simply turning the switch from OFF to TTL you can take beautiful images.
