Will this work: G2 + Nikon SB-600? I am worried about frying up the innards of the G2 if the SB-600 were not set right.... I believe the Nikon SB-600 was the last flash Nikon made that would couple (I think the term is TTL?). I almost never use a flash so I know very little about them, however, I'm considering buying a G2 and don't want to have to buy that Contax TLA-200 flash if I can get by with the Nikon SB-600? Any G folks out there? Sean, Rich, others know?
