New dome lens design

Newly designed high performance fly-eye dome achieves ideal even light distribution underwater with a 110 degree beam angle without sacrificing strobe power. High performance, multi-function and easy handling due to the light-weight underwater all in all you get an excellent underwater strobe. 

Strobe functions

The S-220 is equiped with with a sync flashsystem that work together with the pre-flash and main flash in camera’s built-in flash or optical TTL converter/Trigger, the S-220 can deliver full power even at 1/1000 high shutter speed setting without cutting power. The S-220 strobe is equipped with circular metal heatsink carrying high thermal conductivity around light emitting area. The heatsink can release heat generated inside of the strobe by each shot effectively to underwater. Improved heat tolerance has resolved heat problem typically accompanied with powerful strobes. No sudden stops in firing you strobes for them to cool down. 

The built-in Auto-Off focus light delivers 220 lumen brightness as support when focusing a subject and it works in synch with the shutter release and automatically turns off when firing the strobe and on again after a second. The back pannels symbols and text are made with a high-intensity phosphorescence material to improve visibility both during day and night dive.

S-TTL auto mode or 12 steps manual flash mode

The S-220 has the proven and reliable auto exposure system S-TTL that will benefit you with easy yet reliable accurate exposure and high firing rate. In addition the high performance slave sensor never miss the camera’s trigger signal even faint or partially damaged fiber optics cable can trigger the strobe to offer faultless triggering. With highly accurate increments, 12 steps, the manual flash control is onboard when the situation requires fine manual flash output. 

The "Strobe Light Shade" is bundled as standard accessory. It dramatically suppresses flare or "ghost" reflections of the cameras lens and backscatter when a strobe is positioned in the vicinity or ahead of the lens port by blocking the light that can reflect of the lens port.
