Has it not been firmly established in this forum that the linear resolution of a Bayer sensor is between 50 and 75% of that implied by the MP value, and is it not the concensus of this forum that, on average, the said number is 70% in the real world of color images - not "luminance equivalent", whatever that obfuscating phrase means.

This article says it pretty well , IMHO:

http://www.melbpc.org.au/pcupdate/2303/2303article4.htm

So, 30MP at 3:2 aspect ratio = 6708x4472px. Effectively, 6708x0.7x4472x0.7 =4696x3130px = 14.7MP.

In other words, the OP has said nothing new, in spite of the exclamation mark in the title - sorry, Gary.

Please do pardon me for providing a reference and quoting actual numbers
