[QUOTE="J-see, post: 418271, member: 31330"] I think I know what goes on. I was checking my focus just before and it's a bit misty. I set focus perfect with live on a pod, switched the lens to manual and when pushing the focus button to see what the cam indicates, it keeps jumping between its <o> indicators. It never settles to the focus dot. The last time the lens messed up, it was misty in the morning too and likely, even when I was shooting later on and no longer seeing any mist myself, there might still be have been a thin layer that messes up the AF. Or it's possible that creates some difference between the AF upon wide open and the shot taken closed down. I'll go shooting in a bit to know for sure. It's not because I no longer see mist, the AF can't be affected by it. It should also explain why I hardly ever had a problem before it got colder. [/QUOTE]
