Vibration felt EF 100-400mm L IS USM

I have just received one of these lenses, 2nd hand.

It is very, VERY nice but I have noticed there is a faint vibration felt when IS is triggered by half pressing the shutter button. I also notice that, at times, the image seen in the viewfinder moves slightly during this vibration, I am not sure if this movement is one way or "there and back again".

Also, one or two seconds after the shutter button is released, there is a similar though perhaps weaker vibration felt. If the image seen in the view finder moves during this second vibration it is very little, so little that I can't differentiate with certainty between such a movement or the consequnce of my head moving.

Are these vibrations etc. normal in this lens?

Thanks for any assitance/answers.
