A high-performance YS-90AUTO strobe has been added to the SEA&SEA YS-90 series. Designed to fully utilize the advanced features of digital cameras, YS-90AUTO is adjustable through a range of 12 f-stops (f22/f16/f11/f8 /f6.7/f5.6/f4.7/f4/f3.4/f2.8/f2.4/f2) and offers improved performance. For digital cameras with manual aperture control or program auto function, you simply turn the dial to adjust the aperture level of YS-90AUTO and you are ready for auto strobe lighting. No more trial and error adjusting of manual light level controls. Just leave it on the auto sensor and YS-90AUTO supplies the appropriate amount of light. This strobe has excellent performance characteristics including the pre-flash mode. Connection with the optional YS-90 fiber optic cable makes this strobe compatible with most compact-type digital cameras. Auto strobe lighting is also available with the digital SLR housings with our strobe sync cord (s).
