The iso was different, too, to compensate.

According to DXO Mark's measurements, the 7D has a rating of 854. If you normalize this to full frame, you get 2156, compared with 1815 for the 5DII. Thus the 7D sensor is more sensitive. (And, according to what I've read, it has lower read noise as well.)


I admit, however, that these measured results may differ from real world impressions.
