I have a Canon EOS 50D which I got for a bargain price. I did an initial inspection but was not able to check the sensor properly due to the location (and probably inexperience on my part.)
The sensor is filthy - looking through the lens is like looking at my dog's bed - bits of hair, fluff and spots. The question is: Can this be fixed with a normal sensor clean by my camera store or am I likely to have to replace some expensive part? The camera itself still has the remainder of the original owners extended warranty though I am quite sure that does not extend to the camera rolling around a dogs bed

I do have it booked in for a sensor clean tomorrow but was hoping that I could get your opinion on whether it can be cleaned or did I blow my dough.

I am attaching a photograph I took of the blue sky when I returned home - dust Nazi's beware, you will find this image disturbing
