I've been out in Canada for the last couple of week and been snapping away. Its been pretty dark, Cloudy Rainy out there, most of the time i was have to shoot a fast speeds, being on a boat so i had to bring the ISO up to 400 to get any decent sort of lighting.
When i'm looking at the shots at 100% on Adobe Raw there seams to be so my noise. I can reduce it a little in pp but i loose the sharpness, to be honest i never really expected to see noise at 400iso.
My question is, if i upgrade to the 40D will the noise at high iso's be significantly less than the 400D. I was contimplating the 5D but i would have to save for the rest of my life.
