I recently moved up from the 300D to the 20D, which means I am new to pentaprism viewfinders, and have a question.... My viewfinder has a speckled appearance, as if the image were covered with tiny little black dots. They are hard to see, you can only pick up on them against a white background. It gives the whole thing a textured appearance.
The pictures I take show no sign of this, they are fine.
Is this a normal thing, or do I have a faulty mirror or pentaprism? Or could it just be dirty?
TIA
