A review of the TURTLE

In the latest issue of Underwater Photography Web Magazine (UwP 95) Alex Tyrrell published an article about his experiences with the TURTLE TTL-converter’s Nikon version.

The renowned underwater photographer who tested our product regularly runs UW photo workshops as well. So we were really curious about his opinion. We’re happy to share his conclusion: “Overall I am very impressed with the TURTLE and consider my money well spent. I’m also happily surprised at how well the TTL performed, particularly the shooting speed.”

We highly recommend to read the full in-depth review with the test shots and detailed experiences. We would like to thank you for choosing and reviewing our product, Alex- we wish you nice shots with the TURTLE!


Sony owners, the TURTLE is coming!

When we started planning our first TTL converter certainly we chose the camera to use with what we owned: we made a TURTLE for the Nikon cameras. The next step was the Canon version. So when we’re started introducing the TURTLE for the world of underwater photography we felt the majority of the photographers will happy with our TTL converter solution.

In January we visited the Boot Show in Düsseldorf. We met some partners in the diving industry, showed the converter underwater housing makers and distributors. While they were interested in the product many of them asked us: when can we make a similar product for Sony cameras?

After a little bit of research we found out the Sony became more and more popular in underwater photography. This made us thinking and to cut a long story short, we decided to develop a TURTLE TTL converter for Sony cameras.

We’re happy to announce the completion of the first version. We added a gallery of test photos to show the TURTLE works with Sony as nicely as with the Nikon and Canon cameras. Certainly we still have a lot to do, we’re preparing for extensive testing and fine tuning with different cameras and strobes. But hopefully we can start shipping the TURTLE TTL converter for Sony cameras in a few weeks! Are you interested? Please write to us (info@trt-electronics.com) and we can tell you more about the details!

Camera: Sony Alpha 6000 (you can find EXIF data in the photos)

Strobe: Inon Z240

Functions: 1st curtain,  Rear curtain, flash exposure compensation, full ISO range


A TURTLE for every setup

The TURTLE TTL-converter is really small so it fits in any older or newer underwater camera housings. There are Nikon and Canon versions, it works via fiber optic cable or sync cord, you can use it with many kinds of strobes. If you upgrade your setup, buy a new camera, new housing or new strobe, you can use the TURTLE with them.

We tested the different setups but the most important is the satisfaction of our customers. We’re really happy when we can help improve an older camera setup’s capabilities with our TTL-converter. Would you like to see how the TURTLE fits into different housings? Here are some examples!

One of the setups consists a Nikon D60 in Sea&Sea housing and Sea&Sea YS-110 strobes with sync cords. The other setup is a Nikon D300 in UK Germany housing with Sea&Sea YS-D1 strobes which works either sync cords of fiber optic cables.

Guys, thanks for choosing the TURTLE TTL-converter! We hope you will share the photos which you shoot with these setups!


The TURTLE in the Nemo33

Last weekend we visited Brussels and dived in the huge pool of Nemo33. A pool like that is a good place to test a TTL converter, because of the very different lighting conditions depending the depth and the place inside the pool. We were sure the TURTLE will work fine but we always look for chance to test, review and improve.

We are satisfied with the results of the short dive. 40 minutes is not enough to make a serious model photography session but we tried to test the setup (Nikon D7100 camera and Sea&Sea YS-D2 strobes) in the shallow and deep parts and in the artificial cave. We share the photos we took to prove the TURTLE TTL converter worked fine as usual.

We are grateful for the Nemo33 because they let us dive with the full camera and strobe setup!


The TURTLE in the boot

We visited the boot show in Dusseldorf to meet some of our partners. We talked to underwater housing manufacturers, we got a lot of feedback and discussed the possible developments. Stay tuned for the news- we have exciting plans for the future!

We are happy to announce you can find the TURTLE in several shops, so you can visit our partners’ websites if you want to order you TTL converter from your local webshop.




Happy New Year!

We had an exciting year in 2016: we started selling our products, the TURTLE TTL converter for Nikon and Canon cameras. After many tests and redesigns we finalized the small but powerful gadget which will make life easier for demanding underwater photographers. Stay tuned for news and reviews and if you have any questions, feel free to contact us. We would like to thank to everybody who helped us and we wish a Happy new year! Hopefully all of us will have awesome dives in 2017 and those who use TURTLE TTL converter will share their exciting photographs!



Canon 7D Mark II and Sea&Sea YS-D2

Our goal was to create a TTL controller which works with the widest range of cameras and underwater strobes. That means we are continously test different combinations and if we should, modify the software of the TURTLE.

We’re happy to share this test video of a Canon 7D Mark II camera and Sea&Sea YS-D2 strobe combination. The D2 is one of the newer, popular compact but powerful strobes from the Sea&Sea while the 7D Mark II is one of the best APS-C format cameras for underwater photographers. In this video you can see as they work flawlessly with the TURTLE TTL controller.


Wide Angle photography by Damir Zurub

We’re really proud when renowned photographers test the TURTLE TTL-controller and share their shots with us.

Recently our friend, Damir Zurub visited Raja Ampat in Indonesia with a Nikon D810 camera in BS Kinetics housing and Inon Z240 strobe set with fiber optic cord- and certainly with a TURTLE inside the housing! We find the wide angle photos convincing- hopefully you think the same!

New feature: manual control!

The TURTLE V1.0 controller provide TTL exposure control for many Nikon DSLR camera and underwater strobe combinations, the device automatically sets the exposure on your strobes when the strobes fire. We tested it with all available Nikon models, it’s compatible with even older models like D200 or newer ones like D5. It works with Sea&Sea, Inon and Ikelite strobes both with fiber optic or electrical cords. So with the TURTLE you can use a wide range of Nikon cameras and different underwater strobes in TTL mode.

But for more creative control we added a new feature to the TURTLE: now you can switch to manual control easily even under water with Nikon cameras. If you switch on the LCD backlight with the power button, you can change between TTL and manual control. If the camera goes into standby/sleep mode, when you turn it on, the default mode of the TURTLE will be the TTL exposure control.

Hopefully this new feature will be popular amongst demanding underwater photographers. Both control modes work with fiber optic and electrical cords.
