RetraFlash PRO Underwater Strobe

This item is discontinued. Please find accessories and technical data here.

Product number: RE10003

Developed by underwater photographers for underwater photographers - with this claim Retra UWT has dedicated itself to the development of one of the best underwater flash units in the world. 

Focus on light quality

With a unique flash tube design and a completely new reflector, Retra-UWT has achieved a light output that no other flash unit of this size can offer. But it is not only about guide numbers.

"All you need to remember about guide numbers is not to use them as a guide when buying a flash. The guide number is determined by both the light output and the spread of the beam. A focused beam produces a much higher guide number than a widely scattered beam, but the latter is more desirable underwater." Alex Mustard in the Underwater Photography Masterclass (2016)

The user interface created by photographers

By listening to underwater photographers using the original Retra Flash, the developers have optimized the user interface. The interaction and functionality of the new Retra Flash is even more intuitive and precise.

Double O-ring and leak detector for the battery compartment

Our goal is to achieve a 0% statistic for battery compartment flooding. Therefore we introduce a double O-ring on the battery cover and on the optional leak detector. In the unlikely event that the battery compartment is flooded, you will be notified by the Retra Flash to check the battery compartment as soon as possible.

Macro rings for RetraFlash
The macro and super macro rings reduce the angle of light and are perfect for getting up close and personal with your subject. The larger diameter Macro ring is mounted into the Reduction ring and locks via o-ring friction. The smaller diameter Super Macro ring is mounted into the Macro ring and locks via o-ring friction. Macro rings work only in combination with the Reduction ring.  The Reduction ring can be purchased separately.

Reflector for RetraFlash
The Reflector increases the light output by +1 F-stop (in water) and narrows the angle of light. The light output is ideal for macro and CFWA photography in manual or TTL mode. The Reflector is securely mounted into the Reduction ring and locks via o-ring friction. Compatibility: The Reflector works only in combination with the Reduction ring. The Reduction ring can be purchased separately.

LSD Ultimate Light Shaping Device
Blitzmodell: RetraFlash PRIME/PRO
Das Lichtformungsgerät ist speziell für Ihren Unterwasserblitz entwickelt worden. Die Lichtformungseinheit (LSD) funktioniert wie ein Projektor, der das Licht von Ihrem Blitz- und Pilotlicht nimmt, um einen Strahl mit einem scharfen Bild im Fokusabstand zu erzeugen. Das LSD verwendet Elemente wie Linse, Maske und Diffusor, um den Lichtstrahl zu erzeugen. Der Lichtstrahl Es ist einfach zu bedienen, auch bei deinem ersten Tauchgang! Wenn Sie die Kontrollleuchte einschalten, können Sie genau sehen, wie das Bild aussehen wird, bevor Sie den Auslöser drücken. Auf diese Weise können Sie schnell die richtige Position für Ihr LSD finden und mit der Aufnahme beginnen. Scharf - Weichzeichnung Du kannst Licht formen, seine Kanten schärfen oder verschwimmen lassen. Das linke Bild ist mit dem fokussierten Lichtstrahl. Der Fokuspunkt liegt bei 175mm vom Rand des LSD (in Wasser!). Das rechte Bild ist mit dem Lichtstrahl leicht unscharf.  Doppelloch-Präsentation Beleuchten Sie zwei Stellen mit der Doppellochmaske. Zwei Spots zu beleuchten war eine unmögliche Aufgabe, mit dem LSD ist es einfach! Sie müssen die Doppellochmaske einsetzen und den richtigen Abstand zwischen den Löchern finden. Die Positionierung ist ein Kinderspiel, denn Sie haben die Kontrollleuchte, die Ihnen zeigt, wo die Projektion sein wird.   Verwenden Sie das LSD für kreative Beleuchtung.  Der starke gerichtete und gebündelte Strahl des LSD ist perfekt, um mit der Position Ihres Blitzes in Bezug auf das Motiv zu spielen. Verwenden Sie es für die Seitenbeleuchtung oder die Hintergrundbeleuchtung.  " Eine leistungsstarke Verwendung der LSD besteht nicht darin, einen Spot in Ihrem Bild zu erzeugen, sondern einen Spot zu erzeugen, der groß genug ist, um Ihr Motiv und Ihren Vordergrund, aber nicht den Hintergrund zu beleuchten. " - Alex Mustard Beleuchten Sie größere Flächen im Weitwinkelbereich. Das leistungsstarke LSD kann auch für Weitwinkelaufnahmen eingesetzt werden. Das ist besonders interessant, wenn wir dem Thema näher kommen.     Das LSD ist zukunftssicher Wenn Sie Ihren Blitz wechseln, wechseln Sie nur das Montagemodul. Jedes LSD besteht aus zwei Modulen: dem optischen Tubus und dem Montagemodul. Sie sind über vier Schrauben verbunden und können in wenigen Minuten ausgetauscht werden.

Bumpers for RetraFlash
Blitzmodell: Pro X / Prime X / PRO / Prime
The Bumpers are fitted to both ends of the Retra Flash to protect the edges during rough seas. Both Bumpers feature double o-ring seals which keep them firmly in place and need to be mounted dry. All accessories for the Retra Flash (Supercharger, diffusers, LSD, rings, etc.) are mounted normally when the Bumpers are installed. The Bumpers do not get in the way of other accessories and keep the edges of your Retra Flash protected. For maximum protection we highly recommend using the Bumpers in combination with Neoprene for Bumpers.
