What is geometric QE? Never heard of anyone else using that measure.
I think the 30% QE figure is more correct for a 5D mark iii. That would be in line with colour CCDs using Bayer matrix. 15% would indeed be woeful but as we know that is not the case. I see about 1/2 the light sensitivity
60% QE ML8300 or PL16803 in my Canon 40D.
Are there low light high ISO samples of 5D mark iii done in RAW anywhere or are the only examples just jpegs?
I saw some samples showing low noise in jpeg form but obvious heavy noise reduction reducing detail quite a lot. A bit of a scary thought.
I hope the claims of low light high ISO performance isn't only in camera noise reduction performance. Posted RAW images are what are needed to confirm this aspect of the camera.
