Re: Are those figures for "print" or "screen"? (nt)

The OP is really more interested in whether a 6Mp compact will be a

an artifact of other design choices made that reviewers don't like.
In particular, what are the theoretical and practical limits in IQ if
you downsize to 6Mp?

The only downside of fewer MPs is that you cannot print as big at high resolution. 6MP allows you to make a 10 x 8 print at 270 dpi, and for ordinary purposes (a print framed behind glass and displayed in living room light and viewed from a meter or two) 270 dpi is plenty. So it is uncontroversially true that a 6MP compact will not be a worse performer than an otherwise identical 12MP compact unless you want to make very large prints. On the other hand, there is no such thing as otherwise identical 6MP and 12MP compacts, and if a 6MP compact had a less good lens that a 12MP compact it's images might be visibly worse, despite the advantages of bigger pixels. The excellent advice to pay no attention to MPs cuts both ways!
