The exif might give us some clues but it is missing.

Auto focus does struggle with brilliant snow scenes and on bright days it's hard to be sure how it looks on the screen.

There's always the chance it was accidentally nudged onto macro or something.

Thanks for moving this jane.

4WD I was using manual focus at the time, ive tried using the same lens today and it seems ok. Must of been a combination of using it at the wide angle end of zoom, and my focusing error.

Was the centre of the lens steamed up in the cold? This can cause a soft focus in the middle of the pic.
