have been playing with this flash i just got. i put it on the camera so i can set it to ttl but when i shoot it's way too bright. just figured out searching the threads to put my d70 in commander mode manual for the strobe was setting off the sigma to early. which brings me to my next ?. is it the light that fires the sigma flash? i was hoping i could turn off the built in some way so i was only getting side light or where ever i put the flash. seems like a good enough falsh for the money but have to admit that the manual isnt worth spit. if anyone knows of a 3rd party written guide or something that would be even better.
