sianz... i conclude...

the wireless trigger, working, no problem...
the minolta FS-1200 is working... no problem also
the minolta HS-5600 & HS-3600 is working... no problem also...

the problem i guess lies in this... the timer in the wireless trigger... cos most flash, just need 1/*** very fast short circuit to activate, then minolta i think need a longer timing... which is y, other cameras cannot activate minolta's flash... (the SECRET IS OUT)

cos i disassembled all the parts & test, strange enuff... minolta need 1 metal place there then activate, and the flash trigger just give a super short pulse to it... but it triggers other flash without a problem.

forgot to thank:

Drudkh for organising
muko for a look at the really cool 5D DIY vertical grip
eow for the focusing tips

and

DCA for the CMI flash experiment
(jk only lah. but hope you can figure out a way to use all the stuff)

this is possible...
Pulse width spec can be different...

but have a bit doubt...

if my assumption is correct.... i think no wonder we always have flash shutter lag... cos the time to activate flash is longer... (lagggggg)

you got osciloscope?
can measure what is the time required..

then maybe we can do something with the experiment..he..he..

just now went to change my sunblitz flash, den talk to the technician there... cos wanting to buy 1 of those flash to act like my slave...

he mentioned something that minolta have a delay flash which is different from other brands... forget to ask in depth... aiya... perhaps thats the problem...

 

[muko]

dont have...
he.he..
only office got one...
but very difficult to smuggle my cam inside...
later cannot go out...

hmm... this is probably one of the weakness of our flash system...
