Hm. How do you get "photons" by multiplying the shutter duration (milliseconds?) by the aperture (f-stop? pupil diameter?) by the sensor area (mm^2 perhaps)?
That was actually a serious question.
Maybe I'll ask it another way. Here are the values to plug into your formula.
Using your formula, can you tell me how many photons are "collected" by the lens?
No, because I don't know how much light hits the lens. We are comparing sensor formats here, but since you have decided that you don't want to learn how equivalence works, I won't bother you. All the necessary explanations have been provided but you have chosen to ignore them, every time. Good luck with the further cultivating of your ignorance.
Edit: By the way, the lens doesn't collect photons. The sensor does.
I think one of the posters above was confused about equivalence, but I'm not (happily).
