The Godox Speedlite TT685 is a powerful external flash with LCD screen. Thanks to the guide number of 60, this flash has a large maximum range, making it easy to spot a model or subject at a distance. The LCD screen shows all information about selected settings. By turning on the backlight in the dark, you can also adjust your settings effortlessly. The zoom head has a range of 20-200mm and can be adjusted manually or zooms automatically, so you can be sure that the lighting is correct. You let the flash easily communicate with the camera thanks to the built-in master and slave receiver. This allows you to experiment with low key lighting.
