Review on 📷 Fotga 39.4" Remote Control Shutter Release Cords Cable for Panasonic GH2 GH3 GH4 GH5 GH5s RM-VP1: Enhance Camera Control and Efficiency! by Rich Ferguson

I really like this article. Something wireless would be better, but the cord is long enough for minor inconveniences. For the price I like it very much, but I can't give it a 5 because I can take photos and shoot videos on the GH4 in M mode. The trigger doesn't know the difference. I assume this can be configured via the menu settings as these Panasonic cameras are very "customizable". Until then, straight out of the box and into the camera, you can't use the shutter button even in manual mode (the record button in M mode doesn't do anything).
