12e- is not great Greg, but it's a 9x9um pixel and collects a lot of photons. A 7.4x7.4 um pixel is 2/3 the area so you'd expect read noise of 8e- assuming no improvements in the technology. As I mentioned, the Sony chips do much better. It's not that you can't produce good images with high read noise but it takes a lot more data... and it's not like we get a lot of good weather!
Cheers,
