So what happens when a noob's new cam's sensor's got dust in it?


You do what most will do: 'Clean it'

The other option is sell it.
 

Actually dust on sensor is a very common problem. Unless its affecting your images, i.e. you can *see* the effects of the dust bits on every shot you take, you can basically ignore it. Otherwise you'll be spending your energy trying to clean the sensor rather than shooting more photos or doing post-processing on your images!

Just relax on the dust, and enjoy shooting with your camera. :) Give it another 3 months or so later and you'll automatically forget about the 'problem'.
