Thank you for viewing. This is a Godox TT600 flash for Sony cameras. I mainly use another flash, so this unit has rarely been used. It has only been tested a few times indoors, and the number of flashes is low. The protective film is still attached. I have confirmed that it fires when attached to an α7RV and α7CII for this listing. It also fires in S1/S2 mode, synchronized with light from other flashes. The 20mm-200mm zoom function is also working. The original box and case are included. Batteries are not included. Accessories are also included as a bonus, so please check the photos. Thank you for your consideration.
