DPReview:What is equivalence and why should I care?

[CAT-THE-FIFTH]

I saw this posted elsewhere,and its really a good article talking about sensor size and aperture,and how it affects the quality of the final image:

It is really worth a read IMHO!!

Regarding the lens argument that is also making the assumption that larger sensors always have lower photo-detector densities than APS-C sensors,which is not always the case. When it comes to low light abilities,its the amount of light gathered by the lenses and the individual photo-detector area(but the back end parts of the chip,and other technology can complicate things),which are probably important determining factors IMHO.
