Hello and welcome to my first blog post related to flash photography.  Today I am going to tell you more about speed light  Godox TTL685.

GODOX Thinklite TTL TT685C Camera Flash 2.4GHz High Speed 1/8000s GN60 for Canon EOS DSLR E-TTL II Autoflash (TT685C)

 I am a Canon shooter, and after a year of using I will tell you my impressions. Let’s start with the company who produce this flash unit and explaining some terms and features for which I think that are very important for one speed light.

About Godox Company

According to the Godox official website (Godox) , company has been founded in 1993 as GODOX Photo Equipment Co. Ltd .

They are producing “full line of studio photography equipment, including studio flash and portable power inverter, outdoor flashes, continuous lighting, studio flash accessories, camera flashes, macro lighting, speedier power pack, camera flash accessories, flash triggering and control system, and other studio accessories”.

Similarity and Compatibility with other Flash Units

The Godox TT685 is similar to the V860II, so the specifications are pretty identical. The Godox TT685 acts as a slave or master flash, so it can control other flashes like the Canon 600EX-RT, 580 EX, and can receive signal from them as well as pop-up flash commands from the Canon 7d mk2, 80d or similar. The Nikon variant of the controls is SB-900, SB 910 and the like. Just as it receives commands from a Nikon dSLR camera. A similar situation is with the Sony model, which controls the HVL-F60M, HVL-f43M and the like.

For which Camera Brands this model is available?

Model appear in 5 variants Godox Thinklite TTL TT685 

  • C (Canon),
  • N (Nikon),
  • S (Sony),
  • F (Fuji) i
  • O (Olympus and Panasonic.

What Package include?

The Godox Thinklite TTL TT685 comes complete with a carrying case and stand. Without batteries it weighs 410 grams  while with 4 AA batteries it weighs 530g and measures 64 x 76 x 190mm. A firmware update via USB port is also available.

Battery Characteristics

Unlike the Godox V860II, which has a 2,000 mAH Li-ion battery for the power source, the Godox Thinklite TTL TT685 is powered by 4 AA batteries, like most standard flashes. The Godox Thinklite TTL TT685 delivers approximately 230 flashes at full power and 0.1 – 2.6 seconds recovery (measured on a 2500mA Ni-Mh battery). The so-called. Power Saver, which switches off the flash after 90 seconds or 60 minutes if set to “slave”.

High Speed Sync

High-speed sync flash is your DSLR’s ability to use a flash at shutter speeds faster than the camera’s native sync.

This is very useful function which can help you when you find yourself in the situation that requires faster shutter speeds in order to capture the action. Otherwise it is possible to capture blurred image.  This flash allows you to capture images, to set your shutter speed up to 1/8000, which is really great feature.

Exposure Compensation

Great feature which allows the photographer to add exposure compensation to output power of their flash units, which allows a photographer to reduce dynamic range by brightening dark areas without effecting the exposure or brighter areas. 

Exposure Compesation

(FEC) is available in +/- 3 EV in 1/3 EV steps

TTL, Manual and Multi Mode

This flash has 3 operating modes; below you have in short explanation for each of them.

  • TTL   mode is practically automatic flash mode on your digital camera. A TTL flash will automatically use the camera’s built-in metering system and the distance to the subject (based on the focal point) to determine how much light to put out.
  • M or Manual mode allows you to set all flash features as you want.
  •  MULTI mode allows the flash to go off multiple times per shutter click. You are able to set how many times it will fire and at what time interval those flashes will go off. With MULTI mode, you can uniquely capture movement in one exposure.

Of Camera Use

There are a few simple ways to use this flash of the camera:

  1. First requires to use at least 2 flash units, one is going to act as your master controller from the camera position.
  2. Another way is to use dedicated wireless transmitter/trigger, Godox X1
  3. And the third way is to use pop up flash (if your camera has built in flash).

Slave 1 and Slave 2 mode

This flash has 2 slave modes, S1 and S2. The main difference between these 2 modes is when you have a camera or flash that has pre or metering flash. For example, if you are using built in flash to fire your external flash, every time you half press your shutter button in S1 mode, you will have pre flash on both flashes, pop up and external flash. In case you are using S2 mode you are not going to have pre flash on your external flash. That is the main difference.

Conclusion

My opinion is that Godox TTL 685 is the best option you can get on the market, when you compare price-quality ratio. For about 110 usd you will get a reliable device with   many features like exposure compensation, auto (ettl) mode, you will be able to trigger other flash units with this speed light, to have about 230 flashes at full power.

Auto TTL mode is very important, especially in situations like children birthdays, when you don’t have enough time to set your light. Flash photography requires a longer learning curve, I am not saying that it is complicated, but surely has a lot of to learn. I will try to explain in the future posts, in the simple manner some basics of flash photography.

Cheers,

Pick your perfect Camera.
