brainiac:
You don\'t seem to be thinking clearly: if you need to crop 10/18 of the 7D frame, then you also need to crop 10/18 of the 40D frame, given any particular lens and shooting distance.
I do not mean to prolong this discussion, taking too much time from you and others but I have to clarify the lack of my \"clear thinking\".
The comparison that I am trying to make is nothing else than comparing \"pixel noise\". I do know that this term does not really exist for you because you want to look at the whole image and capabilities of a camera in this respect.
I wanted to look at the same number of pixels images to see if 10 Mpixel images taken out of 18 Mpixels will give a better image than 10 Mpixels of 40D. If that is the case, everything is completely clear to me as far as the progress Canon has made. If not, I will have to find out what size of 7D full image crop is equal to 40D\'s image.
If I know that, I would be able to see if the increase of \"cropability\" is worth $1700 for me. I know, as I have already said, that you do not want to think about \"pixel quality\" and that is the closest, I can come to, in my quest to understanding how good 7D is.
