Re: 50mm 1.8 STM AF Noise... Really?!

Maybe I have bad lenses too but my EFS 24f/2.8 STM and my EF 50 f/1.8 STM are both noticably louder to focus than my EFS 10-22 which uses a USM motor.   I know the STM  lenses focus smoother and don't have the fast start/stop of a USM  motor but I don't believe the silent part at all.
