I want to build a sensor for my Canon EOS 5D III that automatically takes a picture whenever a lightning strikes. I know that you can as well simply keep the shutter open and set the aperture etc accordingly, but I want to try this approach as it feels more "healthy" for the camera.
The sensor is definitely very fast and will trigger a shot almost instantly, but I wonder what delay the camera itself brings into the game? To be clear: I'm not talking about the shutter speed (e.g. 1/200 sec) but the delay, thus the amount of time between triggering a shot (via shutter button or remote control) and the camera actually starting to record the image.
I could not find any info on that. The delay will surely be quite small, but I'd like to be sure that it is small enough before I start building my sensor.
