[QUOTE="uksweetheart, post: 591616, member: 42933"] Hi, I have a small problem that to be honest could be user error :) I go to the local Parkrun on a Saturday to photograph the runners, have never noticed this problem before but this morning but while I was there my ISO kept changing drastically from one shot to the next. today I had my camera set at shutter priority 1/2500, f/2.8 and ISO on auto: sensitivity 100, maximum sensitivity 2500. I won't go into a long story so I'll make it short. The sun was over my right shoulder and as I took a shot of a runner, shutter and aperture stayed the same in all the shots I took this morning but occasionally the ISO went from 250 up to 2500 yet the weather conditions stayed the same. I didn't move from where I was stood and I tried to take each shot as the runner came to it in the same place so the lighting didn't change. I'm hoping someone can help me by explaining why it would do this?. Lens was a 70-200mm and the focal length I used was 200mm. thanks for any help [/QUOTE]
