Theo, since you are an Engineer by training I will reply using the familiar to you terminology. Any optical system such as a lens acts as a low-pass-filter and has its own resolution. You want the sensor matrix to sample the image at this resolution or better. Since in the real world people own multiple lenses with different resolutions (and you have one of the most impressive collections I have seen) it makes sense to sample at the highest rate to be consistent with the best lens you have. Oversampling does not hurt if the software can gracefully resample to the appropriate output resolution.

I've mentioned that before in one of my statements Leo... I do understand that nobody can possibly read all statements if a conversation have advanced, but if you look under my comments, I am sure you'll find it... By the way, you was posting at the time I was supporting (kind of) another statement of yours...

In fact the key words in your post are "Oversampling does not hurt if the software can gracefully resample to the appropriate output resolution." but the thing is that because of diffraction (of which the size differs with lenses) there is sometimes "false analog oversampling" by the lens that is (inevitably) magnified by digital....
