Spot/flare/dirt in the viewfinder?!?

If it was on the sensor it would be in the shot

It could also be stuck between the focusing screen and the pentamirror/prism. This is fiddely to get to.

How bad is it? I would recommend just living with it. The service techs would charge you a lovely premium to clean it.

Yeah I know about the sensor cleaning, however feel it's a bit overkill to have it clean after every startup. I clean it on a regular basis manually instead.

why? this is what the feature is for..... I have it set to clean on start up.... you always start up after swapping lenses and this procedure can shake the dust before it settles.....
