The Pro Max has the highest power output of the new Retra Flash Series, a fresh OLED back panel display and offers the highest level of versatility that is appreciated by all underwater photographers. Engineered to Perfection For over a decade, a group of engineers and underwater photographers have teamed up with a single goal in mind: develop a true lighting tool for underwater photography. To reach this goal, we continuously examined feedback from photographers during every step of the development process. The end result is a travel friendly strobe that delivers top-tier performance in any lighting condition. So, whether you're a professional or just diving into the world of underwater photography, the Retra Flash will be your trusted companion on all your underwater adventures. 4th Generation of Underwater Strobe Technology With our 4th generation series, we listened to all your comments and made changes to the Retra Flash to better suit your needs. Electronics were completely redesigned with efficiency and performance in mind 4th Gen. Retra Flash uses less power for the same light output Optical triggering system is more reliable and able to read optical input even from sub-optimal fiber optic cables. Intuitive Back Panel Controls We've spent hundreds of hours analyzing feedback from photographers on the field and tweaking our designs to bring you a back panel you are immediately familiar with. We're also introducing a brand new innovation that is the centerpiece of the new Retra Flash Pro Max. The OLED display shows relevant information based on selected mode. The information is uncluttered and clearly displayed - even in sunny shallow waters! Information that can be seen on the display: Current mode Power setting Battery life indicator Capacitor recycle indicator And more! A reliable power source is the key Our 4th generation Retra Flash models have a completely redesigned battery compartment that can now hold 8x AA cells without the need for a separate battery compartment, when using the Booster. The Retra Flash is also the only underwater strobe with a built-in leakage detection system that warns you if water gets into the battery compartment. 

The Retra Flash Pure is a new addition to the Retra Flash family. The Pure is our entry level strobe, designed for anyone looking to dive into the world of underwater photography. The Retra Flash Pure features a smaller flash tube, which makes it a perfect match for the LSD snoot, allowing you to take breathtaking macro images. Performance in numbers Flash power: 70 Ws Power source: AA rechargeable batteries Circuit protection TTL Bluetooth connection Bayonet connection type: A1

The Wide angle diffuser shifts the color temperature by -500K and softens the light by reducing the overall light output by -0.6 F-stop. The Wide angle diffuser is designed for all types of wide angle photography in blue waters.

The Shark diffuser shifts the color temperature by -1000K and reduces the overall light output by -0.8 F-stop.  The Shark diffuser is designed to prevent overexposing shark bellies and to give an especially warm light output for a more vivid blue background. The Shark diffuser is suitable also to other large animals and schools of fish. 

The Wide angle diffuser shifts the color temperature by -500K and softens the light by reducing the overall light output by -0.6 F-stop. The Wide angle diffuser is designed for all types of wide angle photography in blue waters.

The Soft diffuser shifts the color temperature by -200K and softens the light by decreasing the overall light output by -0.3 F-stop.  The Soft diffuser is especially suited to green water dives and general wide angle or close focus wide angle situations where a soft light is required with minimal color temperature Offset.

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.

The Reduction ring narrows the light beam of the Retra Flash and helps reduce backscatter for macro or low visibility photography. The Reduction ring is used as a base module for the Reflector and Macro rings accessories.

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.

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.

If you want to change the Mounting module on your LSD you can buy it here. 

Das kreative Maskenset besteht aus: 6 elliptische Formen, die nützlich sind, wenn das LSD in einem Winkel zeigt und Sie dennoch einen kreisförmigen Scheinwerfer erstellen möchten. 4 Doppellochformen mit größeren Durchmessern für Tiere mit größeren Augen 4 quadratische Formen mit einer größeren Abmessungsspanne im Vergleich zum Standardmaskensatz

The round mask set is designed for photographers looking for the perfect spotlight. You can choose from 12 different diameters ranging from 2mm to 24mm.
