Inon Z330 Underwater Strobe

S-TTL Auto /13 Steps Manual Flash Mode

Proven and reliable INON's unique super accurate auto exposure system "S-TTL" Auto mode (patented) is onboard to support easy and solid underwater shooting with appropriate exposure.
In addition, optimized high performance slave sensor never miss camera's trigger signal even with faint signal or partially damaged fiber optics cable can still trigger the strobe not to bother you with unstable flashing.
Precise 1/2EV. increment 13 steps Manual flash control is onboard as well to support professional use where fine power adjustment is required to provide highly accurate lighting..

EV. Controller to Adjust Exposure of S-TTL Auto

It is simple to fine-tune flash power in S-TTL Auto by dialing the EV. Control Switch on the back control panel. Adjustable range is 3 steps to increase and 6 steps to decrease. It is easy and simple to suit to your intended exposure or different exposure control characteristics among camera models.

Bundled "Strobe Light Shade" to Prevent Shining Camera Lens

Radiation System to Release Generated Heat Inside

The Z-330 strobe is equipped with circular metal heatsink carrying high thermal conductivity around light emitting area. The heatsink is directly connected to inner circuit component to release generated heat from strobe usage effectively.
Improved heat tolerance has resolved heat problem typically accompanied with powerful strobe. No stress with sudden stop of flashing to cool down.

Minimum Recycle Time "approx. 1.6 sec." at Full Flash

Minimum recycle time at full flash (how fast the strobe ready lamp shines and the strobe is ready after making full flash) is approx. 1.6 sec.(*3) achieving fast recycle time even delivers powerful light.

(*3) With recommended Panasonic "eneloop pro", BK-HCD, 1.2V, Min.2,500mAh. Recycle time based on INON test data.

On-board Wireless TTL

The high sensitive slave sensor enables wireless S-TTL Auto mode using a mirror instead of an optical cable. Attaching optional Wireless Connection Kit on the Z-330 and combined with an underwater housing via Shoe Base Set or Grip Base D4 Set creates a handy S-TTL Auto shooting set.

* Not compatible with camera's on-board wireless system such as Olympus wireless RC flash system or Nikon creative lighting system as wireless flash system differs.

Integral Pre-flash Mode Detecting Function

Fully compatible with a camera which alters number of pre-flash between once or twice making total flashes twice or three times depending on shooting condition. The Z-330 automatically detects number of pre-flash to activate adequate program to support proper functioning of Manual as well as highly accurate S-TTL Auto mode.
INON unique Advanced Cancel Circuit benefits you with faster recycle time and more images per battery set to eliminate drawbacks when using Manual Flash mode with a pre-flash type digital camera where the built-in flash always burst full dump.

As of December 2017. Specifications/product design/price subject to change without prior notice.

(*1) Compatible flash mode/connection method varies depending on combined camera system and usable flash mode differs depending on connection method. Refer to the user manual for detail.
(*2) Measurement in air/ISO100 at 1m without "Strobe Dome Filter SOFT", nominal value.
(*3) Underwater, nominal value.
(*4) Calculated from a spec. chart of LED manufacture, nominal value.
(*5) Measured with FULL strobe output at 30-second intervals with both Focus Light and Advanced Cancel Circuit OFF, at 25ºC/77ºF with test batteries giving 5 minutes cooling period every 50 flashes.
(*6) Operable duration is accumulated time of continuous mode with 5 minutes cooling period every 30 minutes at 25ºC/77ºF with test batteries.
(*7) Recycle Time/Flash Capacity/Focus Light operable duration based on INON test data. Actual values may vary using different battery manufacturer, battery type etc.
(*8) Not all Ni-MH batteries are confirmed compatible as some "conventional" or "high-capacity" NiMH rechargeable batteries have significant self-discharge and heat-generating characteristic causing difficulty to keep their performance during usage. Only when "eneloop" or "eneloop pro" batteries are not available, use good quality of Ni-MH rechargeable battery having less problem described above.
