I need a bit of an education from you guys.
What effects noise at higher ISO or longer shutter speeds? Is it purely processor related or does the pixel size of an APS-C body contribute as well?
I own a 500D and I was put off by the 7D not having a definite advantage when it came to noise.
I so hope this is the one area they focus on. The top Canon APS-C body, that many will attach their 400mm+ glass to should be just better.
Sensor temperature - quite strongly, apparently.
