Compact yet Powerful GN22
In spite of its 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.
Super Wide Beam of 140° Horizontal x 100° Vertical Underwater Created by Fly-eye Dome Lens
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 M67/M55" + "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.
Reliable "S-TTL Auto" and 12-step "Manual Flash"
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.
Large Wheel Dial for Greatly Improved Controllability and Phosphorescent Control Panel Improves Readability
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.
Double O-rings Significantly Reduce Flooding Risk
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.
Front Adapter Base for Flexible Lighting
The adapter base to install mount adapters such as the "Z Adapter MV" and "Direct Base Ⅲ" is located forward close to the light-emitting surface, instead of rearward as in the earlier models to prevent optical cable interference.
Operates on 4 Readily Avaiable, Inexpensive AA Batteries
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.
Various Dome Filters
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.
