Question about Canon Speedlite 580EX II (1946B002)
I have two 580ex II's and I use them on both my 7D and my 40D. Occasionally while shooting quick candids and manually adjusting aperture and shutter speed, my flash will switch it's self from ETTL to TTL and the only way that I've found to get the flash back to ETTL is to turn everything off, remove the camera batteries, including the internal battery and reset the camera. Does anybody else have this problem?
