I have been playing with my 2 cameras, a D1H and a D40, comparing the exposure metering on them. I shot the same scene (the view I get out of my front door every time I go out :smile using the same lens (12-24 Nikkor) at the same focal length (24mm) and same aperture (f/8) and same speed (ISO200). The initial idea was to see if there was any disernable difference between prints from the 2 cameras made at my usual 8.4 x 5.6inch on A4 print size. However when I downloaded the images into Lightroom V1.1 I was surprised to see that the 2 cameras idea of correct exposure were quite different, the D1H gave an exposure of 1/750th sec at f/8 which is just what I would expect from the sunny f/16 rule, here is the image: Subscribe to see EXIF info for this image (if available) Now I did bracket this and the shot with a third of a stop more exposure is probably technically ideal with the white walls of the far buildings just blowing but it is marginal. When I shot with the D40 the exposure was 1/320sec at f/8 with this result View attachment 108231 It needed -2/3 to -1 stop bias to match the D1H result. One other interesting point here is that as well as quite distinct metering differences the sensors, though both nominally ISO 200, seem to have different sensitivities; the D40 seems to be 1/3 to 1/2 stops slower than the D1H I obviously have to do some more controlled tests but would anyone care to comment?
