Ashok,

Ignore this information the Nikon rep was either very new at the job or
was not a Nikon rep! Its well known and promoted by Nikon reps knowing
the CLS wireless system that once the master/slave grp's are set that's
all you do any information set on the master will be transmitted to the
slaves in the pre flash sequence.
I can back this up by the fact I use CLS on almost all my shoots
requiring flash, I use 6 sb800's, 4 sb200's and a sb900 all run from a
commander and I have no trouble with changes in iso or lens at any time.

Regards paul
