Despite of compact body, the S-220 spreads high-power GN22. The full-scale performance coupled with a wide underwater beam angle provides unparalleled performance as a main strobe in all areas, regardless of whether for wide-angle or macro photography or compact digital camera or SLR camera.
A precisely calculated and uniquely designed fly-eye dome lens for the light-emitting part attains extraordinary underwater beam angles of 140° horizontally × 100° vertically with minimal light distribution variation.
This wide beam angle perfectly fills the "UWL-95S XD" + "Dome Lens Unit III" underwater coverage of horizontal 140° x vertical 100° (at 4:3 aspect ratio), enabling a single S-220 strobe to illuminate the entire image.
Equipped with reliable and proven INON original high-precision automatic "S-TTL Auto" flash control system and 12 step "Manual Flash" function with -0.5EV. increment.
The S-TTL Auto system can be used not only with camera's built-in flash but also with INON original TTL converter equipped with INON housings, "X-2 R6 Mark II","X-2 R6" and "X-2 R5" for even more precise TTL system. You will never miss a shutter chance.
Redesigned large control wheel and switches significantly improve operability. In addition, the rear control panel is white-based highly illuminant phosphorescent material, ensuring easy-to-read usability both during day and night diving.
The battery box is waterproofed with a double O-ring system, consisting of an oil-bearing yellow O-ring and a black O-ring. This greatly reduces the risk of accidental flooding.
Ball adapters such as the "Z Adapter MV" and "Direct Base Ⅲ" is located forward close to the light-emitting surface, instead of rearward in the previous models not let an optical cable to interfere lighting flexibility.
The S-220 strobe is powered by four AA batteries that are widely and reasonably available. Especially rechargeable nickel-metal hydride batteries such as "eneloop" and "eneloop pro" are recommended, as they can be used repeatedly and reliably, and can withstand cold temperatures.
The S-220 strobe is equipped with a bayonet mount to use various dome filters.Packaged dome filters are "Strobe Dome Filter S [SOFT]" which increases strobe beam angle to horizontal 150° x vertical 110° while reducing light intensity by -0.5EV. and "Strobe Dome Filter [ND]" which reduces light intensity by -4EV. specifically for macro imaging.In addition, two optional strobe color filters are available: Strobe Dome Filter S [4900K] and Strobe Dome Filter S [4600K], which warms native strobe color temperature 5500K to either 4900K or 4600K.
Using "Quick Base S" or "Quick Base M6W" with the "Quick Holder Set Z" attached on the strobe adapter mount enables one-touch attachment/detachment of the Quick Holder System. The "Quick Base M6W" is especially recommended as you can remove the LED light when shooting still images.
