Excuse my unscientific language, I am just an amateur. I was thinking of a model to describe resolution in terms of photons registered vs photons sent out from a strict pattern. How many photons travel the lens and arrive at the proper positions in space. Or maybe it's total nonsense.

Like counting all the photons and their energies?

Thank you for the info. Could you pass me any link to such calculators? It's good to know that the issue is understood and long resolved among professionals. Out of curriosity, how do you define resolving power of astrophotography glass? In lp/mm? TIA.

Thanks. I ordered the book from. Time to brush up in optoelectrical engineering.

There is a strong belief among some photo pundits that a higher resolution sensor will always extract extra resolution from all existing lenses.This is supposedly based on Fourier transforms of modulation transfer functions of the imaging chain. Is it true? Do math models of imaging sciences...

I placed this in quantum department but since no comments came either it belongs here or is too trivial. Please comment. MY POST IN QUANTUM PH. FORUM ... " This problem I encountered in my photography forum. A new model of camera comes out with a much higher megapixel sensor (Nikon D800...

Or does this issue belong to classical physics? I mean, in my mind I see a lemon running out of juice at some point of the squeeze. Isn't the information coming through any given lens limited then? No more photons to be converted into electrons? On one hand it's the issue of quantum efficiency...

This problem I encountered in my photography forum. A new model of camera comes out with a much higher megapixel sensor (Nikon D800, 36mpix). I argue that such sensor will need new lenses to be meaningful. Others claim that a given lens performance (here resolution) is always utilized by a new...
