The best \"pixel\" size is around 7 um for current CMOS designs.
That\'s photon physics and not marketing ad jingo.
Small pixels are not Hardy pixels.
May I ask you, did you take the statement \"Small pixels are not Hardy pixels\" from a textbook on \"photon physics\"? If yes, can you give me the link, please?
You can check any number of current textbooks on Semiconductor engineering design - warning they are college and quatum math level.
Its basicly signal vs noise and leakage currents.
I have been out of college for over 30 years so dont think you want you want the few I have left.
Actually you should check current or take some optics and engineering courses.
Thats where folks learn this kinda stuff. Not Photo forums.
There would be way too many pages to scan and dont think many could understand the formulas.
Alternatively, you could just look at actual fair tests done between concurrent cameras with radically different sensor pitches to see if your armchair quantum physics misunderstanding has any truth in it. If you do that you will see that a 1Ds3 (6.4µ) does iso 12800 just as well as a D700 (8.5µ):
And you will see that a Fuji FZ50 (1.97µ) does iso 13,500 just as well as a Canon 400D (5.7µ) PER SQUARE INCH OF SENSOR:
..and the more you look into it the more you will discover that your preconceptions about 7µ being \'magic\' are simply nonsense.
