I have been able to verify that the viewing image is affected by the blemish on the mirror. The affect is increased as the aperture is closed down (higher f-stop).
As it appears as a dark spot on the image, it can affect focusing ability.
What do you suggest the best solution might be? A partial refund or should I return the camera body for full refund?
