75/300 USM IS shake during focusinggreenspun.com : LUSENET : Canon EOS FAQ forum : One Thread |
Hi! I just bought a new lens 75/300 USM IS. I found a strange thing. When I hold the camera in vertical & foucus on a object, there is a sound with a slight shake thru' the view finder. May I know if it is normal or not. Anyone can help? Thanks a lot!

Normal, don't worry about it.
