New TURTLE Mobie TTL converters

We are redesigning our product line in 2018, and now we would like to introduce the new TURTLE Mobie TTL converters.

Tha new models have the same basic features: they offer TTL for many camera models (we have Nikon, Sony and Olympus/Panasonic versions) and they work with a lot of the underwater strobes manufactured by Inon, Sea&Sea, Subtronic, Seacam or Ikelite. The new TURTLE Mobie models can be charged via micro USB socket.

We offer the Mobie converters for those underwater photographers who use housings with smaller space to place the converter. We already manufactured these TTL triggers for Nikon, Canon and Olympus, but now it’s available for Sony as well. The new TURTLE Mobie for Sony will be useful for the owners of Sony A6000 series camera models or those who use Nauticam housings.


Introducing the 2018 TURTLE TTL converters

As you may noticed, our TTL triggers changed a bit recently. From 2018 we will sell redesigned units for Nikon, Sony and Olympus. The new, smaller, smarter units get the new, stronger LEDs, and can be charged via Micro USB socket.

The basic capabilities are the same, the Nikon, Sony and Olympus models work with many camera models, and the strobes can be controlled by sync cords or via fiber obtic cables. We tested it with the most popular underwater strobes (Ikelite, Inon, Sea&Sea, Seacam, Subtronic), and the list of compatible strobes is growing.

Thanks to the experience we gained in manufacturing during the last year, the new units will be cheaper than the old ones.

We have new plans, so check back regularly to learn about the new products!

Adjusting the light level of Sea&Sea 110a strobes

As you know, we try to test all the strobes with the available settings of the camera to ensure you get a perfect exposure when use TURTLE TTL converters. But some of the problems don’t occur when we test the setups.

After some feedbacks we started testing the Sea&Sea YS-110a strobes again with every possible settings. Although in TTL mode it shouldn’t matter the setting of the light level we found out if we set the light level to the minimum the TTL converter can’t work correctly with the strobe. In this case the photos will be underexposed especially between the F4-F11 range.

When we made the test photos after adjusting the light level of the strobe to the maximum, the results were completely different, all the photos were perfectly exposed in the full range. (In the photo below we made a shot from F4.5 to F22, with a Nikon D7100 camera and two Sea&Sea YS-110a strobes.)

So for those who use the TURTLE TTL converters with Sea&Sea 110a strobes we recommend to set the maximum light level all the time- except when they use the manual mode.

Sorry for any inconveniences! Please if you have any problems, contact us, and we try to solve them.


Boot 2018 Special Offer!

The TURTLE TTL converter automatically sets the exposure on your strobes when the strobes fire. With our product, you don’t have to worry about setting your strobe power for each shot. You’ll get a good exposure even when your subject is moving fast. But we built in the manual setting feature to the TURTLE TTL converter so whenever you want to set the power by yourself, you can do it.

The TRT-Electronics released its first TTL trigger for Nikon DSLR cameras a bit more than a year ago. Since then we developed Canon, Sony, Olympus TTL converters which work with many camera models and a wide range of underwater strobes (the most popular Sea&Sea, Ikelite, Inon models). We were happy to see the photos taken with setups which included our trigger from our satisfied customers.



The demanding underwater photographers who want to use TTL strobe control under water like our products, but we always try to improve them. Although the basic features are the same from the beginning (works with many cameras and strobes, you can change between TTL and Manual mode, the battery lasts for many dives without recharching, it’s small and easy to use), we listen to the feedbacks. So we will offer a bit modified TURTLE TTL converters from 2018.

We decided to give you a chance to get one of the 2017 TURTLE TTL converters which we have in stock now so we announce a great TURTLE TTL trigger sale for the Boot show in Dusseldorf.

Canon 5Ds with TURTLE project

One of our customers had a dream. He planned to travel to the Lake Baikal and wanted to shoot photographs above and under water. So he bought a Canon 5Ds camera with 11-24 lens.

We offered our help to assemble the complete underwater setup. We suggested an NA 5DSr housing with Ikelite DS 161S strobes. As he needed remote control as well, we designed and built one which works from 10 meters distance.

Certainly our customer needed a reliable TTL trigger as well for his camera and strobes, so our e-TURTLE 5Ds trigger was a perfect choice for his setup. In the photos below you can see how we built it inside the underwater housing.


Great news for Olympus users

We’re really proud of the feedbacks from our customers who are satisfied with our Nikon, Canon or Sony version TTL-triggers. But certainly some people ask about our plans or share their ideas what should be our next development.

We listened to you and because we were asked about a TTL-trigger for Olympus cameras we decided to work on it. And now we’re happily share the first test shots with the new o-TURTLE for Olympus cameras.

We have to finalize the product, but in a few weeks you can order your o-TURTLE from our webshop or purchase it in one of our dealers’ shop. If you have any questions, feel free to contact us!

Nikon D810 test

As our customers use different camera models for underwater photography, we try to test as much models as we can. Recently we had the chance to test the TURTLE for Nikon TTL-trigger (more exactly, the tiny TURTLE XS) with the Nikon D810 and Inon Z240. We tried it with different aperture and ISO settings and here comes the test shots with the different settings. What do you think about the results? We’re quite satisfied!
