I understand their real QE to be about 30%.
Not sure about that Peter. Absolute QEs are quoted for a few Sony sensors on the Point Grey site - understand they do their own measurements.

Current mono ones (and even the 285, which has been around a while) have peak QEs somewhere between 60 and 80% and >50% through the Bayer filters for the colour ones. Most interesting is the high QE of the new back illuminated CMOS devices - they have no gates to get in the way. Interesting times on the way?
