Does anybody know a way to make flash working in auto mode while using M mode?
I use G3 in macro shot (reversed 50 mm or closeup lens using an intarnal flash diffuser similar to one shown on http://www.iaw.com/~pturton/diffuser/index.htm) and when I shot macros outdoor in sunlight, often the standard synchro speed (1/60) is slow enuogth to get shot moved (even if camera shakes or subject moves). Of course using highest available synchro (1/250) fixes the problem, but the only way to set such speed still controlling aperture (I must use f8 to have max DOF), is to use M mode causing flash to be switched to manual mode loosing in this way the E-TLL automatic flash exposition.
According with 420EX external flash unit users's manual, it seems to be a G3 limitation since 420EX can work in automatic mode with M mode (on cameras other than G3).
Regards
