The Nikon Z 50 has no analog trigger, only the ML-L7, a bluetooth one.
I'm not sure what is the delay between said trigger and the photo (it cannot be too fast, there's Bluetooth in between), but in any case it has no external analog input.
I would like to trigger the Z 50 using sound (bursting balloons, or small explosions) so I'm looking for a way to use sound. For balloons of course I could trigger a flash with a long exposure on the camera, but small explosions don't work with flashes, so I really need an audio trigger.
What are my options?
