Inon Publicizes S-220 Strobe

Inon has introduced the discharge of its new S-220 strobe. The S-220 boasts a information quantity (GN) of twenty-two and a beam angle underwater of 140° (horizontal) × 100° (vertical). The strobe affords S-TTL auto and 12-step guide flash modes.

The S-220 is supplied with a “fly-eye” dome, which expands the sunshine protection. The strobe options a big wheel dial for higher controllability, whereas the phosphorescent management panel ensures glorious visibility even in low-light circumstances. It operates on 4 AA batteries and options double O-rings to cut back the chance of flooding.

The S-220 is suitable with a wide range of bayonet-mount filters: (i) Strobe Dome Filter S [SOFT], which will increase the beam angle to 150° (horizontal) x 110° (vertical) whereas decreasing gentle depth by –0.5EV; (ii) Strobe Dome Filter [ND], which reduces gentle depth by –4EV for macro imaging; (iii) Strobe Dome Filter S [4900K], which adjustments the 5500K native colour temperature to 4900K; and (iv) Strobe Dome Filter S [4600K], which adjustments it to 4600K.

Obtainable quickly from retailers similar to Backscatter, the S-220 is priced at $420.

Extremely Vast, Excessive Energy, Compact Underwater Strobe

  • Compact physique but delivers GN22
  • Geared up with a fly-eye dome lens enabling tremendous broad underwater beam angle of horizontal 140° × vertical 100°
  • Dependable and confirmed “S-TTL Auto” and 12-step “Guide Flash”
  • Massive wheel dial for dramatically improved operability. A phosphorescent panel for simple readability
  • Double O-rings tremendously cut back the chance of flooding
  • Entrance positioned base contributes extra versatile lighting
  • Operates on 4 AA batteries, available and fairly priced
  • Suitable with varied strobe dome filters
  • Helps “Fast Holder” for simple one-touch attachment/detachment

Regardless of of compact physique, the S-220 spreads high-power GN22. The total-scale efficiency coupled with a large underwater beam angle offers unparalleled efficiency as a most important strobe in all areas, no matter whether or not for wide-angle or macro pictures or compact digital digicam or SLR digicam.


Tremendous Vast Beam of 140° Horizontal x 100° Vertical Underwater Created by Fly-eye Dome Lens

A exactly calculated and uniquely designed fly-eye dome lens for the light-emitting half attains extraordinary underwater beam angles of 140° horizontally × 100° vertically with minimal gentle distribution variation.


This broad beam angle completely fills the “UWL-95S XD” + “Dome Lens Unit III” underwater protection of horizontal 140° x vertical 100° (at 4:3 side ratio), enabling a single S-220 strobe to light up your entire picture.


Dependable “S-TTL Auto” and 12-step “Guide Flash”

Geared up with dependable and confirmed INON unique high-precision automated “S-TTL Auto” flash management system and 12 step “Guide Flash” perform with -0.5EV. increment.

The S-TTL Auto system can be utilized not solely with digicam’s built-in flash but in addition with INON unique TTL converter geared up with INON housings, “X-2 R6 Mark II”,”X-2 R6″ and “X-2 R5” for much more exact TTL system. You’ll by no means miss a shutter likelihood.

Massive Wheel Dial for Enormously Improved Controllability and Phosphorescent Management Panel Improves Readability

Redesigned giant management wheel and switches considerably enhance operability. As well as, the rear management panel is white-based extremely illuminant phosphorescent materials, guaranteeing easy-to-read usability each throughout day and evening diving.


Double O-rings Considerably Scale back Flooding Danger

The battery field is waterproofed with a double O-ring system, consisting of an oil-bearing yellow O-ring and a black O-ring. This tremendously reduces the chance of unintended flooding.


Entrance Adaper Base for Versatile Lighting

Ball adapters such because the “Z Adapter MV” and “Direct Base Ⅲ” is positioned ahead near the light-emitting floor, as a substitute of rearward within the earlier fashions not let an optical cable to intervene lighting flexibility.

Operates on 4 Readily Obtainable, Cheap AA Batteries

The S-220 strobe is powered by 4 AA batteries which can be extensively and fairly accessible. Particularly rechargeable nickel-metal hydride batteries similar to “eneloop” and “eneloop professional” are really useful, as they can be utilized repeatedly and reliably, and might face up to chilly temperatures.

Varied Dome Filters

The S-220 strobe is supplied with a bayonet mount to make use of varied dome filters. Packaged dome filters are “Strobe Dome Filter S [SOFT]” which will increase strobe beam angle to horizontal 150° x vertical 110° whereas decreasing gentle depth by -0.5EV. and “Strobe Dome Filter [ND]” which reduces gentle depth by -4EV. particularly for macro imaging.As well as, two elective strobe colour filters can be found: Strobe Dome Filter S [4900K] and Strobe Dome Filter S [4600K], which warms native strobe colour temperature 5500K to both 4900K or 4600K.

“Fast Holder” for Straightforward, Speedy Dealing with

Utilizing “Fast Base S” or “Fast Base M6W” with the “Fast Holder Set Z” hooked up on the strobe adapter mount permits one-touch attachment/detachment of the Fast Holder System. The “Fast Base M6W” is particularly really useful as you’ll be able to take away the LED gentle when capturing nonetheless photographs.
