Ok - so what does this mean in terms of 5-10 minute subs? Simply lower noise?

The issue I think as well with SONY chips is that for the equivalent size probably double the cost?? e.g. QHY9 vs ATIK equivalent in a SONY (in terms of chip size) - although I should be more accurate and say in terms of the ATIK offering which then starts to use larger KODAK chips in the larger format cameras.

My Canon 400D provides a 47.9' x 32.0' field. I really don't want to go below about 40' x 30'

I can see why even though it's been around for a long time the KAF 8300 chip is so popular! and why perhaps the QHY9 is such good value.
