The Sea Frogs SF-01 offers a phenomenal range of features and benefits. Combining high power, wide angle coverage and near instant recycling with thought through user friendly exposure functions and triggering options, the SF-01 leads the field outperforming many much larger and heavier underwater flashguns.

KEY FEATURES:
Powerful G.N. 32 and UNDERWATER coverage 120 degree
Yet lightweight and compact body, the SF-01 is designed to produce G.N. 32
Further more, the SF-01 has overcame drawback of high-power strobe which has long flash duration and reaches to FULL power after start flashing in significantly short period of time.

200 lumen, Shutter-linked AUTO OFF Focus Light
The built-in "Shutter-linked Auto-Off Focus Light" delivers 200 lm brightness to support when focusing a subject and cease in synch with the shutter release and automatically turns ON again.
To aim optical axis of the Focus Light in line with strobe light’s optical axis, the Focus Light has a fresnel lens in front supporting more accurate strobe aiming and improved usability.

Learning Mode /7 Steps Manual Flash Mode
A unique accurate auto learning mode LM has been further evolved. Accuracy of exposure is advanced providing more accurate exposure.
In addition, optimized high performance slave sensor never miss camera’s trigger signal even faint or partially damaged fiber optics cable can trigger the strobe to offer faultless triggering.
Precised 1/2EV. increments 7 steps Manual flash control is onboard to support professional use.

Both Optical/Electrical Trigger Supported
The SF-01 is equipped with a 5 pin sync connector as well as slave sensor to trigger optically to adopt wide variety of camera system.

Automatic Power Off
The SF-01 strobe will turn OFF automatically if it´s not being used for more of 180 minutes. You need to turn the mode knob to OFF and ON again.
