Brand new EF 70-200mm f/4L IS USM clicks and whirring noise from IS
Apr 7, 2012

When I half-press the shutter on my 7D, the IS system on my new lens makes a clear click, then several seconds of whirring, followed by another click as the whirring ends. Neither of my other lenses (EF-S 17-85 and EF 100 f/2.8L Macro IS USM) make the same noises.

Should I take it back, or is this normal for this lens?

Thanks.
