But that’s not all that this flash has. It’s got a radio receiver built in, TTL, groups, channels, manual control, multi-stroboscopic flash abilities, and full incorporation with what Sony’s platform offers.
If you’re a strobist, looking for a budget friendly option and the most bang for your buck for your Sony camera with a multi-interface shoe, then you’d honestly be stupid not purchase this–and I say that with complete and total honesty.
Pros and Cons
- Super reliable
- Automatic transition to high speed sync
- Stroboscopic mode
- Incredible TTL output that meters will with the Sony system
- Well built
- Pretty much gives you an awesome studio option in a small size with loads of features

Looking at the Godox TT685S TTL is like looking at many other very standard flashes. For the newbies, it will be intimidating. For the photographers with experience, it will be a bit of a learning experience, but you’ll get there.
With that said, the back of the flash is dominated by the LCD screen, buttons, and some branding.
The front of the flash has an IR sensor and otherwise lets you look at the rotating head. It’s very much like every other standard flash in terms of how it rotates around.
Turn to the side of the flash and what you’ll find is a cover that exposes ports. If you’ve got other Godox flashes then you can see if your receivers will fit into here. However, the flash has a radio built in so it doesn’t need it.
The other side has the battery compartment. It lays it out in a straight row, which is rather odd and not normal so to speak.
The flash also comes with a fairly flimsy shoe for its foot. There are much better built ones out there that feel much more solid for what they’re worth. Then again, the whole package is affordable.
The Godox X1T-S is the transmitter. On top you’ll find a hot shoe for another flash and a test button. Additionally, you can also spot the branding here.
Turn to the back and what you’ll find here is the large control LCD screen. Plus there are buttons to control the according variables along with a wheel to scroll through.
On the side, what you’ll find are the on/off switch and the back bulb light on/switch. You’ll probably only work with the former.
Both units are built very well and if you put a Sony badge on it, you’d probably think it were true. The transmitter and flash are both not weather sealed though, so be careful when shooting in tougher conditions. Despite this I’d be very confident using the flash and transmitter on any gig that is thrown at me.
It still doesn’t come close to the LumoPro LP-180, which is by far the best built hot shoe flash out there.
Ease of Use
Going through the menus and navigating the buttons accordingly isn’t that difficult if you’re used to many of the flashes that have been coming out in the past couple of years. They’re not simple, but they’re as direct as they possibly can be.
Again though, I recommend that every photographer really goes through the manual unless you’ve got a lot of experience with a variety of flashes. Chances are that many of you don’t work with as many flashes as I do due to my job of reviewing the gear.
This flash does an awesome job at offering TTL transmission with a Sony camera and a lens with electronic information passing through. As long as this was happening, the results were stellar. I’m very happy not only with this but also the manual flash output which seems to be right on par with many other flashes out there in the same category.
For that reason again, I’ve got no issues with this flash.
Some of the images on my personal website and in my latest project called “The Secret Order of the Slice” were shot using this flash. It’s super reliable and offers exactly the image quality I ask it to with exposure compensation and HSS when I need it according to Sony’s metering system.
Let me state this: there isn’t a single reason why this flash shouldn’t receive the Editor’s choice award. The Godox Thinklite TT686S TTL flash is reliable, compact, and simply works. Not only that but it gives the user a whole load of options. You can do slow sync with Sony, second curtain flash, first curtain, it doesn’t matter. You’ll get it and more importantly you’ll get it at a damned affordable price point.
If you need TTL flash output and radio transmutation for your Sony camera, this is honestly one of the best bang for your buck options out there.
The Godox Thinklite TT686S TTL flash wins five out of five stars and the site’s Editor’s Choice award. In nearly seven years of reviewing products, this flash is the biggest no brainer out there for every Sony photographer and you should all pick one up.
