The distance between the sensor and the lens flange is different for each make of mirrorless camera.

Welcome to our forum. I don’t understand your problem, could you please elaborate more?

got a very capable custom built desktop, using the usb-c port on camera->motherboard. 200mb files are quite cumbersome.

I am having similar problems with my YN 560 mark 3 and mark 4 flashes, When set to Multi mode they fire as they should (in multi mode) when I press the test button on the gun. But when the 560 TX transmitter is set to fire the flashes I only get the one flash. The transmitter is communicating with the flashes and is in Multi mode.  What am I (we) doing wrong??

Hello guys, This is a problem we have been experiencing for a long time. I have added a visual example below. There are many more examples on our YouTube channel. Is there a solution? https://prnt.sc/-0qIR9EpahIN Device settings: Shutter - 40 Aperture - 5 ISO - 500
