Well let’s stir the pot a little more, because, a three sensor camera had to push the light through a prism which didn’t (literally couldn’t) perfectly distribute the light to those three sensors. So it’s foolish to think that the “resolution” of one of the old HD cameras was any more accurate a description of the image captured than the terminology used in the present day. Back then you had less precise lenses as well, which then pushed chromatic aberrations and other lens artifacts through a prism, then you still had an interpolation step after each sensor pass where the data had to be merged based on a particular company’s color science approach. There is truly nothing magical about the word “resolution” then or now. And in general, the effective resolution of a modern Bayer sensor sitting behind modern low-dispersion and chromatically corrected glass (and no prism) is going to be appreciably better than the old 3 sensor systems. So I think perhaps Mr. Chapman-who I’m sure is well meaning in his commentary-has not taken the time to consider the technical corner into which he has boxed himself.
