Dear members, I have a chance to buy a Metz 32-MZ3 with the SCA 3102 (Canon EOS) adapter for almost nothing. This Metz also operates in A mode (I have been using A mode on my Metz 45-CL1 exclusively, but this flash unit is very cumbersome). Can someone tell me If my R3 will trigger the flash with the SCA 3102 mounted? Thank You, Miha
