Choose Your Configuration

The Backscatter Smart Control Optical TTL Flash Trigger is available in different configurations depending on your camera and housing. The universal triggers for Sony and Olympus/OM System are designed to fit into most housings and can use either single or dual LED trigger lights. The dual LED trigger lights are perfect for housings that accept LEDs in built-in optical ports or when used with the included foam blocks on a clear housing window. The single LED Trigger Light can be used with the optional bulkhead for a more direct fit. Utilizing built in LED trigger lights, the Nauticam Sony Trigger is custom designed for an exact fit in Nauticam full-frame Sony housings.

Sea Tech has the Smart Control TTL LED Nauticam Flash Trigger for Sony in stock. If you require any other Backscatter triggers, contact us and we can make arrangements for you.

Installing the Backscatter Smart Control Optical TTL Flash Trigger

Nauticam Sony Trigger Installation

The Nauticam Sony Trigger was custom designed to fit directly into Nauticam full-frame Sony housings. To install it, simply slide the trigger onto the camera’s hot shoe, then load the camera into the housing. The LED trigger lights align with the optical ports inside the Nauticam housing for triggering.

The Backscatter Smart Control Optical TTL Flash Trigger for full-frame Sony Nauticam housings is a direct fit.

PRO TIP: For the best data transmission, only use 613 multicore Fiber Optic Cables with the Backscatter Smart Control Optical TTL Flash Trigger, such as those made by Backscatter, Nauticam, and Sea & Sea.

The Backscatter Smart Control Optical TTL Flash Trigger provides super-accurate, automatic flash exposures with Sony cameras using Backscatter strobes. The Sony trigger is TTL compatible with the Hybrid Flash. The Backscatter Smart Control Optical TTL Flash Trigger is more than just a TTL trigger, it also can be used for manual triggering, rapid firing over 30 frames per second, and HSS (high speed sync), all built into a self-contained USB-C rechargeable unit.

The Hybrid Flash, Atom Flash, Mini Flash 2 and Mini Flash 3 all use SC and SC Macro mode when using TTL.

The Benefits of Automatic Flash Exposure

All TTL systems, including Smart Control Optical TTL, have major benefits for photographers of all skill levels. Here are some of the main use cases in which using TTL is beneficial.

Flattening the Learning Curve for New Photographers

Using TTL, flash power is automatically controlled, meaning no manual adjustments are needed to change flash power. For beginners, this makes practicing other fundamental skills such as strobe positioning or changes in camera settings less overwhelming. When using TTL, all you have to do is aim the flash, and concentrate on composition, making using a flash much more accessible to new photographers.

Changing Distances

TTL is perfect for subjects that are moving distances, as there is no need to make manual flash adjustments. When shooting manually, strobe power must be adjusted if the subject moves closer or farther away. If the subject moves closer, strobe power should be decreased to prevent overexposure. If the subject moves farther away, strobe power needs to be increased to reach the subject and prevent underexposure. Using TTL, the flash automatically adjusts power to compensate for the movement of the subject, ensuring correct exposure.

Rapid Settings Changes/Surprise Encounters

In addition to being great for novices, photographers of all experience levels will appreciate TTL for surprise encounters or when rapid camera settings changes are necessary. When rounding a corner and suddenly facing a subject, there may not be enough time to adjust strobe positioning, power, and camera settings if unprepared for the encounter. With TTL, flash power is automatically adjusted, allowing more time to capture the shot during fleeting moments.

Max Flash Output Warning

When the Hybrid Flash and Mini Flash 2 reach maximum flash output, they will sound a warning beep. This makes shooting TTL even easier by providing you with instant feedback if the max power of the flash is reached. If the flash beeps, and the resulting image is underexposed, get closer, or change camera settings to get back into the range of the strobe’s output.

Smart Control Optical TTL can easily and accurately create an automatic exposure. Even if you or your subject changes position, the flash will compensate for the exposure. When shooting with manual flash power, you will need to manually increase or decrease power based on distance from the subject.

TTL Limitations & When to Switch to Manual

TTL works great for most situations, however, there are some limitations to using TTL. This is true for all TTL systems, not just Smart Control Optical TTL.

TTL has one exposure for all strobes being used. If one strobe is closer to the subject than the other, you will need to shoot manually since the strobes will need to be set to different outputs based on their distance. The closer strobe will need to be set to a lower power, to not overexpose the subject, while the strobe that is farther away, will need to be set to a higher power, to reach and expose the subject. If shot in TTL, one strobe will be underexposed or overexposed based on distance.

For an even exposure with strobes set at different distances, you will need to manually decrease the power of the closer strobe and increase the power of the farther one, in order to not over or underexpose your scene.

Since TTL uses multiple pre-flashes, it will trigger slower than manual shooting, and can reach up to three frames per second depending on strobe output levels. Manual triggering, which uses just a single flash, can achieve over 30 frames per second. If you’re looking to shoot rapidly to capture as many frames as possible, manual shooting is the way to go.

Setting up the Mini Flash 2

Smart Control TTL with the Mini Flash 2 is only compatible with the Olympus/OM trigger. Simply set the Mini Flash 2 to SC or SC Macro mode, and you’re good to go.

Setting up the Hybrid Flash

The Hybrid Flash can be configured to work with either Olympus/OM or Sony TTL. By default, the Hybrid Flash is set to Olympus/OM but can easily be changed to Sony. If you are using the Sony trigger, refer to page 15 of the Hybrid Flash manual or watch the setup video for an easy tutorial. This explains how to switch between OM/System and Sony TTL modes and Sony camera models. Once the Hybrid Flash is configured with your camera, you won’t have to change modes again.

Required Camera Settings for TTL

Sony cameras will require simple settings changes in order to use SC Mode TTL with the Backscatter Smart Control Optical TTL Flash Trigger. The settings are easy to change. You can also easily switch between TTL and manual flash operation underwater for maximum flexibility. Please refer to page 10 of the Mini Flash 2 PDF manual and Page 14 of the Hybrid Flash PDF manual for detailed instructions or watch the Sony Trigger setup videos.

Advanced Settings and Features

Flash Exposure Compensation

The Hybrid Flash and Mini Flash 2 use in-camera flash compensation for convenient adjustments to your image. In-camera flash compensation is easier to manage than using strobe controls. This way, you don’t have to set the flash’s power dial in a neutral position, which is easy to forget, or misplace, causing inaccurate results. Using flash compensation in-camera allows you to brighten or darken the image by either increasing or decreasing flash compensation for a specific style. Positive flash compensation will result in brighter, high key images, while negative flash compensation will create a darker, moodier image. To learn how to use in-camera flash compensation, refer to your camera’s manual or check out the video.
