Re: Adaptor reflection fix

Firstly there was a lot dust,  secondly On-Of changer was a bit loose. And there is in the rear of adapter(closest to sensor) a narrow ficure(2-4 mm). It is black but looks different than other black inside adaptor. looks like a marker drawing. Are ghosts in picture coming there. I did not notice those circular artifacts when zooming in the house inside. Has tightening ON-OFF ring helped in tha problem.
