-5 stops of vignetting??? Is is true?
Good radial gradient filters are expensive, but professional optical
shops make them.
Melles Griot comes to mind.

Again, what the f.ck is wrong with you? He's talking about one camera.

Vignetting problem on EF 24-105/f4L IS
Julius Wong Photo.net Patron, oct 02, 2005; 03:04 a.m.
I have used this new lens for over two weeks on an EOS 20D with
satisfactory results. Yesterday I mount it on my new 5D and took a test
shot wide open (24mm at f/4). When I examined this picture on my
computer, not only were all four corners vignetted, the left and right
sides were darkened as well.

I am puzzled over such poor performance of this new US$1250 "L" lens at
the edges. I am wondering whether the old EF 24-70/f2.8L would fair
better.

I took a second shot at my floor tiles. This time not only were there
vignetting around the corners, but straight lines were converging like
my EF 15/f2.8 fish eye lens. Is this suppose to happen at 24mm? I am
considering returning this lens to Canon in exchange for the EF
24-70/f2.8L. Such performance on a full frame sensor is simply not
acceptable.

Full Frame Sensor - The Canon 5D has one, the 20D doesn't
