No more darkness.
Focus on quality of light
User interface made by photographers
We've spent hundreds of hours analysing photographers feedback from the field and tweaking our designs. The end result is a back panel you are immediately familiar with. Controls are large and tactile, for all types of hands or gloves. You will always get what you expected when using the control panel of the Retra Flash.

Underwater flashgun for the 21st century
The new Retra Flash connects via bluetooth to your smartphone or tablet (patent pending technology). Check the status of your flashgun, set advanced features like HSS, Smart SL, Pilot Adjust and get firmware updates with the "Retra UWT" App. The new Retra Flash is a true system that is also built for the future.
Powerful central pilot light: ideal for snooting
Securely attached via bayonet mount there are many accessories available for the new Retra Flash. The most prominent is the LSD Ultimate. With a super powerful centrally positioned pilot light you will be able to find your light spot even in very bright conditions. The Retra Flash and LSD Ultimate are made for each other.
A testing regime worth noting
Over the course of development a combined total of more than 1,4 million test shots were made with prototype and pre-production units of the new Retra Flash. We were looking for failure in every condition and pushing the material to it's limits. The final result is a product that can withstand anything the photographer asks from it. No boundaries, no limits. Pure engineering. 
Made with 2x Retra Flash PRO (prototype)
Double o-ring and leakage detection
The new Retra Flash is the world's only underwater flashgun with a built-in leakage detector (patent pending technology). In the unlikely event of a battery compartment flood you will be notified by the Retra Flash to check the battery compartment at your earliest convenience. Our goal is to reach a 0% statistic in damage resulting from battery compartment flooding.
Design your light without boundaries
With the bayonet mount your Retra Flash can be transformed into a specialist lighting tool. Diffusers for blue water, green water and a special diffuser for sharks are available. For macro work there are several options to reduce the angle of the light beam. Secure mounting is the way.
