Link AF Point and AE: If set to On, this function links the AF point to the Autoexposure calculation in matrix metering mode. If enabled, the subject brightness under the AF point will have increased influence on the exposure determination.
I wish that the Operating Manual had just gone this bit further to explain things. Now I understand.
If it wasn't for this group then I could've gone years without knowing that. The *istD is phenomenal to me and I love it... the manual is at best... inadequate ( I am being polite here

Maybe someone will publish a third party handbook.

I have enabled this, and disabled it, taking a variety of photos in varying conditions, and they all look the same with the same exposures.
What should be happening and when should it be enabled?
Thanks,
Malcolm
