tez przez chwile bylem zainteresoiwany ta lapa, zapytalem producenta i potwierdza on, ze lampa nie dziala z 300D

Much to our regret we have to inform you that the CULLMANN flash 34AF/C does not
work together with the digital camera CANON EOS 300D.

We recommend you the digital CULLMANN-flash unit D-4500 C #60130 which is fully
compatible with your CANON EOS.
