Canon 20D With Canon 18-85IS Lense Dark Corners (Vignetting)

Hi all

Anyone else heard of problems with dark corners on photos shot at wider end
of the lens, using a Canon 20D and 18-85IS lens?

I initially thought that maybe it was due to the lens hood or maybe even the
UV filter, but even with these removed I still get vingetting.

It is worse during dusk/dawn and is particularly noticeable against a clear
sky.

A fault, or so called characteristic?

Cheers

 

the 17-85 USM IS is a toy. Return it and grab a 17-40 L instead

 

I agree with that. I'm just getting a body and that as well as other
lenses. I'm not getting any of the EF-S lenses.

You can get a body and that lens 2049 and change at B&H and have a
far better system.

The 10-22 is a _lot_ of fun. It focuses _amazingly_ close, too.

If you shoot a cheap consumer zoom wide open, and a L lens stopped down to
f/5.6, you should be able to see the difference. Things like CA, soft
corners, light fall off are visible in prints.

The argument for cheap zooms, however, is that _any_ photograph is better
than _no_ photograph.
