550EX metering

greenspun.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?

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.
