in reading a 'blog' post from a sometimes DPreview poster....
i read this... in regards to fine tuning AF lenses...
" Perform this test with the aperture set wide open. Stopped down, depth of field will hide focus errors."
confused... aperture set wide open. Stopped down
the stopped down part - is he referring to metering since the aperture is already wide open??
the post is here...
