I previously asked this question and I understand as well I can use a flash to use as a master to command the SB-R200 units.
I know the SB-800 or the alternative Debao can command 4 channels and three different groups of flashes (A, B & C).
I saw the Nikon SB-910 have exactly the same settings (4 channels + 3 groups) but it is quite expensive. On the other side, the SB-700 seems it can only controls 2 groups (A,B) instead three (I am not 100% sure, but this page seems to confirm it).
Is there any other cheaper flash alternative with these settings:
- A flash (any brand but Nikon iTTl compatible)
- Compatible with Nikon CLS
- Can be Master(commander) with
- 4 channels
- 3 groups
I did like the Metz brand as well but did not find clear information about that specific Master setting on the models I have checked.
