This is so hard to find, countless people have attempted and tried to obtain.
There has been some figures given, but not 100% verified by any data from the manufacturer.
Figures of QE's as high as 40% for the 5D, which is pretty good, as it loses 20% in the debayer process, so really around 70% if it was mono.
QE's of 30% for the 300's and 350's, and the 20D up to about 40% as well.
Like i said take it with a grain of salt, these are not verified, but overall from many many peoples averages.
Again, they lose 20% in the debayer process, and show just how much closer CMOS is comming to compete with Astro cameras.
But its got a long way to match this
