About Yin Yan BY-24ZP flash installed in digital camera!

The fact that high-voltage contact flash will harm automatic cameras (there were no digital cameras at that time, only film machines with high automation such as EOS and Minolta A series used non-mechanical contact to trigger the flash) was just a hype of flash manufacturers as a promotion means of low-voltage flash. At that time, although the network was not developed now, there was really no report of high-voltage breakdown of the trigger circuit inside the camera! ! At that time, I had a Yin Yan 32-index double headlight, which was a high-voltage contact. It had been used on my EOS and never broke down.
