Question about CZ24-70 -strange noise from within lens
Jan 21, 2013

I have had little chance to experiment with my new lens, but I have noticed, today, that when I tip the lens upwards, there is a pronounced and highly audible 'click' almost a 'thunk!' emanating from the lens which seems to relate to some element moving inside the lens.

I am used to floating elements but this seems a little more radical.

Happens on or off the camera, and I am pretty sure (90%+) wasn't there whn I first got it. Can any other 24-70 users please confirm that something is probably loose inside my lens. Thanks

Rob
