Is it normal to have rattling noise - 550D

[alokthapa]

Anyone's DSLR make a rattling sound when shaken horizontally (front and back) ?? Is this normal?
Don't ask me... "why did you do that???"

But now I can't get it out of my head... and have been eying my camera with trepidation, I'm smiling but I'm worried. hahahaha

For my peace of mind... HELP!!

It could be the mirror or the sensor used to determine horizontal or vertical positioning. Moving it back and forwards like that isnt a normal movement, so it would be a lot of things.

Yes, it's normal. See the second item on page 221 of the t2i/550D manual.
