The YS-110 strobe is packed with ground-breaking features designed for the new age of digital photography. When it's connected via a fiber-optic cable to a compact digital camera with TTL metering, the YS-110 strobe offers DS-TTL (Digital Slave Through-The-Lens) light adjustment. DS-TTL follows the camera's TTL-adjusted flash for automatically accurate flash photography. You can use two YS-110 strobes for creative effects with subtle light balance. For example, you can set one strobe to DS-TTL mode and the second strobe to manual mode. The YS-110's mode compensation function provides a light level control dial for just the right balance of light.
The YS-110 also provides full manual control that sets flash intensity that is independent of the camera. The 12-step manual control provides a finely graded variety of light settings up to a powerful maximum setting of guide number 22. Three xenon tubes positioned in the strobe provide a flat balance all the way across a circular beam angle of 105°(with Diffuser), with even and consistent light that will satisfy even finicky professionals.
The YS-110 contains a high-luminosity white LED target light located in the center of its front face. The target light turns on with a convenient button press on the strobe's rear panel, and turns off automatically when the YS-110 flashes. You can connect the strobe to digital SLR cameras and film cameras using the same cables that connect conventional YS-series strobes. You can also connect the strobe to compact digital cameras using a fiber-optic cable.
