550EX meteringgreenspun.com : LUSENET : Canon EOS FAQ forum : One Thread |
I know that the 550EX in ETTL mode links it's exposure metering to the camera's selected focusing point (EOS3 in my case); does this act like a spot meter for the flash? This would make FEL extremely significant. Is the metering area for the flash that small?Derrick

"...does this act like a spot meter for the flash?"No, it just biases the exposure to favor the area surrounding the AF point.

Thanks Jim.Follow-up question: Is the flash exposure linked to whatever focusing point I am using, or is it tied to the center (I think it is linked, but someone please confirm this for me)?

CF 13-0 is for using only the center AF point as spot meter. The CF you want is CF 13-1. ECF or manual selection. But you are limited to the 11 elliptical AF points.
