When this finally was there, I was able to test start:
Age Analog flash Canon works, my 2 other analog unfortunately not. Apparently not enough voltage from etc to solve old analog lightning over medium contact. (The Canon has several contacts)
Thus, I can therefore only with a lightning unleashed flashes or must get me new flashes. :(
The range is more than adequate ... had triggered 30 meters over a distance of approx. Without problems.
What say other recessions, agrees. Every now and then the flash fires, without which one triggers the camera ... read more does not bother, unless you're peeping into the flash. Come guess from other electrical devices, which transmit on the same frequencies.
Around, for the price and amateur photographers like me, totally ok ... Semi-professionals and professionals should engage wertigeren to something.
