So, I have a vintage hotshoe flash that I have for my 120 rangefinder & 35mm slr, however I was thinking since it's small and portable, I could also use it for my EOS-M. Unfortunately, it doesn't seem like the M will trigger the hotshoe flash trigger if it doesn't have a flash with TTL electronics to communicate with the camera. Or am I missing something? I verified it works with my 5D3 in the hotshoe, just not on the EOS-M.
