(Updated - see Pentax *istDL exposure corrections)
The following are 100% (1 image pixel to 1 screen pixel) crops from the exact centre of the frame. All the cameras were tripod mounted. Adobe Photoshop CS2 Smart Sharpen @50% radisu 1 pixel has been applied to each image.

Canon EOS-350D (Digital Rebel XT)
ISO 800


ISO 1600

Konica Minolta Dynax 5D (Maxxum 5D)
ISO 800


ISO 1600

Nikon D50
ISO 800


ISO 1600

Olympus E-500 (EVolt)
ISO 800


ISO 1600

Pentax *istDL
ISO 800


ISO 1600

The above are clearly underexposed, so I have re-done them with +0.5EV correction:
ISO 800


ISO 1600
