Just purchased this lens.
Tried it out in the store and didn't notice a constant whirring from the vibration control. Got it home and now hear it all the time when vibration control is activated.
Description of noise: The whir lasts from the 1/2 shutter depression, through the focusing lock and on until about 1/2 a second after I actuate the shutter. Frankly, I expected some clicks, but I did not expect the long whir...it is making me think the VC motor is bad.
Any similar experiences or did I get a bum lens?
Help would be much appreciated.
