Hmm I have a set of 602's and they fires my SB26 from my Nikon FE2, f90X and F100. I havn't got them to work with my Yashicamat 124g through PC hotshoe adapter. In the near future Ill get a PC to PC caple and try that. Other than that I'm satisfied and glad I didn't paid a premium for a set of triggers.
Alot of "third party" stuff wont work with minolta speedlites because of their silly hotshoe idea.
Best regards
