WyoFoto has a solid side-by-side set of test shots (100% files) that show the image quality of the Canon 40D directly compared to that of the Canon 5D.
The IQ I see in the 40D images from ISO 100-800 is 95% the match of the 5D. At 1600 the shadow noise of the 5D looks to be a tad bit better than the 40D, but not by a large margin. The 40D’s tonality and richness in color gives the 5D a real run for the money. The only area I see the 5D looking better is in low contrast highlight regions. It manages to pull out a tad more detail. The 20D does okay in the shadows, but in the midtones and highlights just can’t match the richness of the 5D or 40D. It’s images while pretty good have a flatter tonal appearance. This subtle richness gives the 5D images the 3D effect people often talk about. (Read *and see* more . . . . )
