Thanks for that Eric, yes I usually have cameras set for 1/3 stop increments. I can see that two sets of variables, shutter speed AND auto ISO may have confused the system.

On the images with sky I should have expected some exposure error for the non sky parts of the image but those without sky have me stumped. I will stop using auto ISO with aperture priority and see if it fixes the problem. May switch to Manual with auto ISO? I like to control my DoF.

It's the garish saturation which hit me first, I had been using the 80-200 with no issues but as soon as I switched to the 24-120 all the car exposures are affected, it's only the image of the field which is OK.

I wonder if the strong reflections from the sunlight fooled the exposure control and caused it to under expose. I tried to position the camera so that I avoided the worst reflections of the sun but it was pretty strong.

I was a bit annoyed that having taken my time with the paddock shots they appear to be a disaster. Will have to see what I can recover...
