Originally posted by Winder If you think that smaller apertures (as in the square area) allow in as much light as larger apertures they you are already down the rabbit hole.
The larger the aperture the more light you project on the sensor. Its a basic rule of exposure. Do you want to argue this point?
Then you do not understand f-stop at all. If you do not understand f-stop then you do not understand exposure. Ergo you do not understand photography.
For the record, aperture is NOT THE SAME as f-stop. Aperture by itself does not explain exposure. You are completely ignoring the effect of focal length. I will not attempt to educate you further. You are very deep down the equivalence-fu rabbit hole like that guy sherman. Getting out of that trap is worse than changing religion. I advise you to stay where you are and continue believing the BS.
