Re: Canon 580ex Mark II
Sorry Mark, I think its just me confusing things. Let me try to be a bit clearer.
C.fn-05 of the 580EX II has 4 options.
0-ETTL II
1-TTL
2- External metering: Auto
3- External metering: Manual
I set the flash to C.fn-05-2 External metering:Auto. With Auto external metering, the camera's ISO and aperture will be set automatically in real time by the speedlight........I missintrpreted this statement. I thought of it like auto ISO. In fact it just means that whatever ISO and aperture I set on the camera, will automatically be set on the flash. The flash does not change anything unless I change it on the camera.
In External metering: Manual.......I have to set the ISO and aperture on the flash myself to correspond with the camera settings. Then if I adjust the cam while shooting, I have to adjust the flash as well. This 'manual' setting applies to other Eos bodies, with the 1DIII I can use Auto.
So when you say you use your Metz on auto, I assume you are using the Canon equivalent of Auto External metering: (am I making any sense yet)
So, The question is......would you think Auto external metering would be better than ETTL II. I know you have not tried it with the 580EX, but I would still value your opinion.
