 Re: Canon 7D | |
Brainiac,
Many people do not print images, but instead view onscreen. I find I have only so much wall space and far more pictures then can fit on the walls in my house.
So we are looking at a full size image on screen, and clicking it to 100% to view detail in the images. That is where the per-pixel noise does become an issue.

Larger pixels do not give significantly better low light performance. That is a myth. The factors which affect low light performance are sensor size, technological maturity, and manufacturer. This camera would have about the same low light performance whether it was 10 Mpixels, 18 Mpixels or 30 Mpixels. You, and the majority, are confused because you are considering noise per pixel instead of noise per square inch of print. Even famous review web sites like DPR make this mistake, so it is not surprising that many are misled. Noise per square inch of print is the real measure of a camera\'s ability to capture a picture in low light, and noise per square inch of print is largely unaffected by changing the pixel pitch, whereas it varies dramatically with sensor size, sensor age, and to a lesser extent, manufacturer.

Everything about this camera seems great, except the 18mp on that small sensor. For people who work outdoors, at lower iso\'s (which, I will grant, is the majority, especially birders and sports shooters) this will be a benefit. I do most of my work indoors in low light. This same camera, at 12 or maybe even 15 mp, could have been the lord of darkness.
