Thanks for responding with your suggestions. I tried to loosen that chrome knurled ring just with my fingers but it would not budge. Before I try putting a tool to it I jut needed to know if in fact it was made to screw off. <br>
If in fact it does then I could reverse the ring on the taking lens with the one on the viewing lens where a filter would not be needed. I did try the filter on the viewing lens just to make sure it was the right size and yes, it did work fine on the viewing lens. So I guess my next question is it safe to apply light pressure with a tool to remove the chrome ring. </p>
