[QUOTE="okulo, post: 502117, member: 40687"] I'm afraid I haven't got around to speaking to Nikon yet; too many balls to juggle at the moment, But I have created an exposure graph which I want to produce before I phoned them which I have added to the page I posted previously. I took an 11x11 sample from the same point on each image (bottom right) using a grid in Photoshop to ensure I got the same area. I then took the RGB values and an average to plot the graph. It's not as smooth as I expected but there are clear increases in exposure in the mid f-stop range which approximate to 33% higher than the extreme f-stop values (f3.5 and f22). None of this is completely scientific as RGB values in Photoshop do not equate to exposure but it is indicative of exposure inconsistencies.
