As of September 2018. 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.
(*9) Measured in fresh water (25ºC/77ºF), nominal value.
