YS-01

Compact design with multiple functions

This new compact type slave strobe can be used for everything from wide-angle to macro photography, and can be switched between DS-TTL (Digital Slave TTL) and 10-step manual control function, allowing subtle adjustment of light intensity to suit the photographer's intention. DS-TTL (Digital Slave TTL) and 10-step manual control function can be switched to allow subtle light intensity adjustment according to the photographer's intention. The strobe is powered by four AA batteries, making it powerful and long-lasting. The power is powerful and long-lasting, using four AA batteries, so you can enjoy shooting all day long without having to change batteries. The recycle time is 1.9 seconds with NiMH batteries (2700mAh), allowing stress-free continuous shooting. Equipped with a high-brightness white LED target light (1W) on the front face to indicate the optical axis of the strobe, which is also effective for night diving. The YS-01 can be used with a wide range of cameras, from compact digital cameras to digital single-lens reflex cameras, either as a main or a sub lens, and allows you to use your creativity to the fullest.

*1 Number of emissions and recycle time are values at FULL emission and may vary depending on battery manufacturer, temperature, and frequency of use.
*2 Data for the number of flashes and recycle time of Ni-MH batteries were measured with 2500mAh batteries (eneloop pro).

*When synchronizing the YS-01 with the camera's built-in flash, please use a fiber-optic cable.
*When using the YS-01 with a waterproof case (for compact digital camera) made by another company, a strobe mask set, etc. may be required together with the fiber-optic cable.
*Using a fiber-optic cable other than our genuine fiber-optic cable may adversely affect the light modulation performance or otherwise prevent the strobe from delivering its full potential. Use of a genuine Fiber-Optic Cable is recommended.

[Precautions for use]
Do not use unspecified batteries (primary lithium batteries, etc.). Leakage, heat generation, or rupture may cause injury or burns.
