I have a question for anyone that reads this post.

One of the exciting features of the new generation of Digital SLRs is a function called sensor clean.  Every time you power up or power down the camera, it vibrates the sensor at an ultra-sound frequency to shake off any dust that may have accumulated when you change lenses.  My understanding that, in addition to the vibrating sensor, there is a statically charged plate below the sensor that attracts the dislodged dust particles.

My question is this – Does the orientation of the camera have an effect on how well the sensor is cleaned?  Is it better to have the camera sitting on its base (lens pointing horizontally)?  What if you’re holding it in your hand and pointing the lens down; is sensor cleaning still as effective?

If you have a thought on this, please feel free to leave a comment.

See the photographs on my website.
