i just picked up my first external flash (430ex II) today and i was wondering if you could help me with something. when i have it all set up and ready to go, i don't get a reading in the zoom section nor in the maximum effective range section.
all i see on the flash's lcd is: ETTL Zoom --mm
according to the manual, i should be able to see this info if i press my shutter half way.
any ideas why this is the case? i have fresh batteries in the flash and i am using an xsi.
