I was referencing Kayaker. I should have mentioned him in my post.

I do notice noise at low ISO's with my 1Ds III in certain landscape situations. It's super minor and I don't really now what it is viewing it at full screen as I usually add a touch of NR even at ISO 100. Pretty much with any camera, there is usually barely touch of noise.

Also I just use a HD monitor, so it doesn't have the finest pixel pitch ever. So it's hiding the really fine stuff better when viewing an image at full screen.

Obviously I cannot comment on your experiences, but I wouldn't doubt it.
