Ricoh GV-2 Mini External Viewfinder

This is an expensive little addition to my Ricoh GR III pocket street camera. It works as it is supposed to. But you should be aware that if you wear glasses this little dude will seriously scratch your lens. To be able to see the full frame brightline you will have to put your eyeglass lens in contact with the view finder, but it is coated with a very hard and abrasive material that will definitely scratch your eyeglass lens.. I suppose you could use a fine sand paper and smooth the rim of the finder. What I did with mine was to paint the rim with a liquid rubber polymer that comes in a tube using a #1 soft artist brush. That works, though it does not look very good. It is hard to imagine why they make these things with such an abrasive surface. So250 for this viewfinder and450 for new eyeglass lens, I could have almost bought another camera. So, I cannot recommend this view finder to anyone who wears glasses, and if I had it to do over I would try the Ricoh GV-1 which is100 cheaper,
