To those who know,
I am suffering vignetting in four corners of the image with the following
combination: EOS3, EF 20mm f2.8 USM and B+W 72 Circular polarization filter
F-Pro. Removing the (original) lens hood doesn't help and the filter is
visually clean (holding the filter againts the light) bes

Hi Craig, Chip, and List,

Henry P is both right and wrong!
Vignetting caused optically from within the lens (i.e as a result of the
distance and angle of exit of light from the diaphragm) is lessened as the
lens is stopped down.
Vignetting caused mechanically from outside the lens (e.g as a result of
filter ring(s)/too l

Hi everyone,
I have just discovered vignetting on some slides taken with my Sigma
70-200/2.8 EX HSM. It's not nice, I can tell you.
It looks like vignetting is strongest in the 70-90mm range, slight around
100-140mm to disappear completely towards the 200mm point. I'd have to
