[QUOTE="WayneF, post: 335410, member: 12496"] This sounds correct if you do not want the exposure to vary. I doubt VR matters if not AF, but it does not hurt to turn it off. If exposure is varying, then look at your Exif on the problem shots, and verify these parameters in fact are not varying (I don't see how they could vary if all is Manual. Auto ISO will vary Manual exposures, but you said Auto ISO was off.) My point is, check Exif to make sure you know the numbers are in fact not varying. The camera tells you what it did. Then, if all is manual and unchanged, and yet exposure is still varying, it would seem like it must the light that is changing. A cloud passing over the sun perhaps? It can make a serious difference. Partly cloudy skies can be a pain. :) If your scene shows shadows, the shadows can tell the difference - dark distinct shadows vs weak vague shadows when cloudy. Did the shadows change? [/QUOTE]
