Don't you mean the sensor?
I would have thought that the mirror isn't as critical? In that it doesn't form part of the shooting equipment (IE Lens > Sensor).

Anyway, I took the lens off last night, pointing the camera down and sort of craned my head, and glinting the light off the mirror, there are dusty bits on there, but nothing major (certainly not a sterile environment, but I don't think there was anything major there).

Talking to Steve last night, he (rightly) made me wary of going near the guts with my brush/lens pen, as it I don't want it or anything or dirt to get on the sensor.

That said, I am looking to get it done.

So I've narrowed out the lens, the outside of the viewfinder (as far as I can see anyway), the mirror. So it's either the inside of the VF, or on the mirror inside or the bit mentioned above (forgive the n00b SLR talk )

If I hold my eye back from the eyepiece a little, it stays in exactly the same spot, WRT the whole area I can see. If I move my head around a little, it doesn't move at all, which if it was on the inside of the eyepiece, then I assume it would at least move slightly?


I understand dirt in the innards is a plausible hazard, given the nature of the whole SLR system, and how exposed it is inbetween lens changes etc.
That said, surely it's shouldn't be fair to expect the customer to 'accept' an amount of dirt in a brand new camera. Not an amount that shows up on shots anyway.
Paying £600 to over £1000 for a camera, I expect them to at least send it out from the factory sterile, or as near as possible.
