For those interested in the pros and cons of "professional" CCD versus CMOS
sensors, there is a brief (marketing style!) article in the latest professional
magazine Photonics Spectra. (available from most university libraries). Only
available as partial abstract online:

This is likely biased because the author works for Dalsa that makes mainly CCD
devices for industrial applications. A few claims : the CMOS sensors generally
have lower fill factors because of higher on chip complexity. The added
metalization layers are thicker putting the sensor at the bottom of a deeper
and narrower well. This leads to more color shifts and more stringent lens
requirements. This is true even when on chip micro-lenses are used. A pity the
article is not better written with a bit more detail.
