Hi,
Juts wanted to check if this use case is possible now or if it could be with a new firmware update?
(e.g. the hardware could do it but it's currently not supported)
I want to feed the exposure signal externally. The frame rate will be lower than the max frame rate for that resolution.
If the exposure duration is taken from the signal or set in the menu is not important. Both will work.
If there is a delay between the ext. trig signal and the actual sensor exposure. I would need a signal out from the camera to drive a synchronized flash.
Alternatively and even better. The delay is fixed and can be calculated upfront for any given setting.
The background is this.
I have designed a Xenon flash that I can control in many different ways with a built in MCU. I would like to take a sequence of images (20 or so at 2k fps) with an exposure time of 6us.
I can't drive the Xenon flash continuously. It can withstand 20 flashes or so but needs to cool down before the next sequence.
I also have a LED based flash for the same purpose. To produce the same amount of light the LED flash needs to be much bigger. Since I am driving it very hard it also has a similar limitation of 40 or so flashes in sequence before it needs to be cooled down.
