Have you got the Alpha logo and the buzzing sound...

...when you turn off your NEX-5N?

Since the last firmware update, an Alpha logo is displayed when you turn off the NEX-5, but that's not the case with the 5N.

I may have since the alpha logo at the start up the first time I turned on the camera. Since then I have never seen the alpha logo on the screen of my 5N, is it normal?

Another thing is when I turn on or off my NEX-5, I can hear a buzzing sound (the sensor cleaning system I think). My 5N doesn't produce that sound, is it the same for yours?
