I wanted to do some studio work with my Mamiya RZ67. I use an inexpensive hot show mounted wireless flash trigger. The mount works fine on my Nikon products, but it won't physically go into the hot shoe on the RZ67 (yes, the hot shoe on my RZ67 is a "hot" hot shoe that works). Does anyone know if the MF cameras would have used a different standard for a hot shoe? Thanks for your advice!
