This is a very good comparison of the portrait shots between Nikon D200 and Canon 20D. The Canon 5D is usin EF 135mm/F2 lens and hte Nikon D200 is using AF 85mm/F1.4 lens. Both uses different focal length in order to get similar photos from both cameras. Both of these lens are highly popular lens for portraits for each camera. Standard settings on both camera are used, which does represent some slight differences in camera default sharpness, saturation, etc. From most of the photos from the website, looks like 5D is obviously better than D200 in terms of ssharpness, clarity, ISO noise.[newline][thumb:596:l:l=g][thumb:595:I:l=g][newline]
