NZtechfreak: They've clearly got different focus points, despite the pre-focusing.
Colours on the second are much more pleasing, although no way for me to know whether they are more accurate since I wasn't there.
I would think the first is the HOX one due to the exposure, likely as a result of the BSI sensor.
How about some full res versions of the images from somewhere so we can see how much noise is in each?
Woops, thought they would be, must be geekzone's backend at work
The first captures the texture of the mouse a lot more, the second thinks it is a matte surface. And yes the second picture represents the colour of the desk better. Halogen light 30cm above the mouse, explains the slight light reflection on each image
