Wow... Thanks guys !
neuroanatomist : Not using mirror lock up ! I don't know why I neglected this !!?... I'll try MLU and silent mode, think that'll do.
bob williams : Thanks for test method, will try that too.
andnowimbroke : Exposure about 1 sec, outside, slight wind, column extended.

Thanks again.

Exposure about 1 sec, outside, slight wind, column extended.

MLU will help, but a 1 s exposure is getting to the point where MLU becomes less relevant (as the duration of the vibration gets very short relative to the exposure, it matters less).

Extending a tripod center column adds substantial instability - avoid it unless you absolutely need the additional height. When choosing a tripod, get one that provides a comfortable working height without extending the center column.
