Hi all,
A few weeks ago i tried some long exposures in Canberra from the mountain. I didn't take my glasses so wasn't able to view my shots well as i took them. What i found was that they were all blurry. I put this down to a breeze blowing and my camera strap flapping the camera around.

Today i tried a long exposure just for testing. My prime lens mounted on the tripod in my kitchen shooting through the window. I used the timer to make the shot so i wasn't touching the camera and still my shots were blurry.

At some point (in frustration) and looking for reasons i turned off the Vibration Control and hey presto! my my shots were not blurry anymore.

Is this an expected result. Should VC be OFF during long exposures. I thought VC was supposed to help but in this instance it is much worse.

For reference my shots were 4 seconds.
