AODELAN P6 Wired Shutter Remote Control (LANC cable)

“For the longest time when I was shooting with my Panasonic GH3, I would just use a wired length controller, and I would set my GH3 to start recording when the shutter was pushed, and since those length cables have a shutter release button, I could just grab my focus with half pressing it and then full press it to start the recording.”
