Review on 📸 GODOX TT350o Wireless Camera Flash Speedlite: High-Speed Sync, TTL, GN36, Compatible with Olympus/Panasonic Mirrorless Digital Cameras by David Sanchez

Works very well. It's a small flash that's easy to carry along with the Micro 4/3 camera. This really makes a difference when you're shooting indoors, even in good light. I saw a review that said the zoom function got stuck at 14mm. Here's the solution. "Make sure your wide diffuser is fully inserted into the flash housing (you should feel a click when it is fully seated - this is the internal switch that tells the flash that the wide diffuser is being used). and ignore any zoom information from camera or flash UI)"
