And you will see that a Fuji FZ50 (1.97µ) does iso 13,500 just as well as a Canon 450D (5.7µ)
Could you please explain that? I always thought that sensor size mattered (even if we may agree that the number of pixels does not have to be detrimental for S/N).
I can try. What you are looking at is an image recorded by EQUAL AREAS of sensor, at equal magnification, and therefore it shows you how good a Fuji FZ50 _would_ be if it had an APS-C sensor. The outcome is that a 400D with a 1.97µ pitch using the Fuji sensor design would be a better low light camera than the 400D is, even though the 400D has a wonderful 5.7µ pitch. It illutsrates that those people who think lower Mpixel sensors offer some kind of iso/noise advantage over denser sensors are just... wrong. The Fuji sensor technology would give the 400D an 84 Mpixel sensor AND be better in low light at 13500 iso. Soon, hopefully, people will begin to understand that fewer pixels does NOT mean better low light performance. It\'s the myth that never wants to die, but we must all kill it if we want better cameras.
Please read this if you want to understand this better and avoid being misled by the large number of outspoken commenters who do not understand this issue but propagate and defend this falsehood like a religious doctrine: http://cyberphotographer.com/megapixelmyth
This is why I look forward to a 50 Mpixel DSLR. The sensor technology already exists and works well, and the benefits will be real and visible in large photographs. When used in good light, such a camera will provide great freedom to crop (i.e. carry fewer lenses).
