lingo confusion
Mar 25, 2013

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...
