Godox flash photography gear

The photos in this gallery show the following photography gear: Fujifilm X-T1 digital camera plus Fujifilm MCEX-11 extension tube and Fujinon XF80mm macro lens; Godox XProF radio flash trigger; Godox TT685F external flash, Godox PROPAC PB960 Lithium-Ion Flash Power Pack; and Quantum Instruments CZ2 Power Cable (for Turbo Series Power Packs).

The Godox TT685F flash head is the same size as a Canon 580EX II Speedlite so slide-on plastic light modifiers that work with a 580EX II will work with the TT685. That said, some work better than others. The “Sto-Fen Omni-Bounce OM-EY” is a tight fit — too tight in my opinion. The “Vello Bounce Dome (Diffuser) for Canon 580EX II Flash” is a perfect fit.

The Godox radio flash trigger and external flash unit are compatible with both TTL and HSS (high-speed sync flash).

The Godox TT685F external flash can function as either a radio master or radio slave. According to the B&H Photo Web page for the TT685F, current as of 01 November 2018, the flash can also function as either an optical master or optical slave.

Much to my surprise, the TT685F cannot function as either an optical master or optical slave. I had hoped to be able to use the TT685F as an optical master to remotely trigger other Fujifilm-compatible external flash units such as my Nissin i40 or Fujifilm EF-X500. This is a BIG disappointment, especially since the TT685C for Canon Cameras features both optical master/slave and radio master/slave modes. Although both the TT685F and TT685C sell at the same retail price point of ~$110, you’re paying for less-capable hardware in the TT685F and that’s just not right! Hey Godox, are you listening?

The Godox PROPAC PB960 Lithium-Ion Flash Power Pack can be used with the TT685F to enable burst mode flash photography. A follow-up blog post will feature a short video clip showing that burst mode flash works quite well.

Editor’s Notes

I contacted B&H Photo on 10 October 2018 via an online chat with a customer service representative named “Dan W.” Dan admitted the B&H Photo Web page for the Godox TT685F is (or was) incorrect. The following quote is an excerpt from the transcript of my chat with Dan W.

“Optical master/slave transmission is available for working with other standard flashes.”


I asked “How do we make this right? I don’t want to return the TT685F but I’d be happy to settle for a discount on another Godox flash.” After talking with a manager, B&H offered to give me a $5.00 discount on another flash unit. B&H misrepresented the product I bought in good faith and their best offer to make it right is $5? Please, get serious.

I have always raved about B&H Photo and its extraordinary customer service. Whenever there has been a problem with an order, it was always resolved quickly in my favor. B&H’s latest offer of a $5.00 discount is an insult and NO WAY TO BUILD CUSTOMER LOYALTY!


As it turns out, the Godox Web page for the TT685F, current as of 12 October 2018, says the flash can also function as either an optical master or optical slave.

It’s noteworthy that the graphic of the flash LCD shows the icon for radio master/slave mode. Hey Godox, does anyone fact-check your Web pages before they are published? This is false advertising!

  2. Godox TT685C Thinklite TTL Flash | walter sanford's photoblog Says:

    […] Godox flash photography gear, published on 09 October 2019, features my initial review of a Godox TT685F Thinklite TTL Flash that I bought from B&H Photo. In short, the flash doesn’t work as advertised by both Godox and B&H Photo, and B&H has failed repeatedly to “make it right.” (More about that in a follow-up blog post.) […]
