Hi Roy the noise is there at lower ISO but I don't think its any worse than the 50D although I don't look that closely. Most of the photos I have taken since I got the 7D have all been high ISO. With the bad weather I haven't been able to go below 800 I have also shot a lot of indoors without flash, using available light. The High ISO is definitely much improved over the 50D.

I post most of my photos on the web at reduced sizes which doesn't show up any noise anyway. As long as the photos are sharp with plenty of detail I really don't bother about it, I can soon clean them up.
