NIKON SB 24 as OCF

hi,
I've been using ocf for a few months now.

I'm used to yn 460 II / yn 560 no iso / aperture

I just got my hands on the legendary NIKON sb 24.

I will use it on pure manual mode ...

Trigger is rf 602's

my questions...

1. will sd9 work / compatible?
2. Why is it on maual mode I could still adjust Apeture / iso ? it should only affect the power output of flash on powersetting right/ zoom?

3. if 1/1 its at full power right even if i put high iso / low f stop.. ( it should not matter right )

Thanks for answering my dumb questions

since no one has answered as of the moment...

Found out that in manual mode ASA/Fstop ( on the flash ) has no Bering at the flash output.

now,

if only some one knows that sd9 will work
