Alpha a33 video - should I get a lot of noise on the audio?

Just bought an a33 secondhand. Pictures look great, and it's in great condition. But video, whether taken in AVCHD or MPEG4 format, has a lot of noise on the audio from camera operation. Even whilst recording, I can hear the camera working inside, is that normal? And this noise is quite significant on the audio on playback. Plus if I switch to manual focus, I also get a very high pitch constant tone on the audio. Is this normal?
