I recently noticed a strange noise on my 17-55 2.8. When I point the lens up it makes a slight humming or buzzing sound, kind of like a low pitched vibration. When I point it back down it makes the same noise for a couple of seconds and stops. The lens does this both when it is attatched to a camera and when it is not. Has anyone else noticed this? Is this normal or should I contact Nikon?
wow, that's odd. maybe there's a bee inside? ok j/k - it couldn't hurt to ask nikon the question. it certainly doesn't sound normal to me. maybe something came loose inside.
