divingbeetle Posted October 5, 2009 Share #1 Posted October 5, 2009 Advertisement (gone after registration) My new item arrived just now. It is Summicron Rigid lens. But I was disappointed see it. It has problem, like seeing from the pictures below. I would like to know what are these stains in lens and why. Link to post Share on other sites More sharing options...

cbretteville Posted October 5, 2009 Share #2 Posted October 5, 2009 My guess would be that it is what is called "balsam separation". This means that the cement that binds two or more lens elements has deteriorated enough that the glass elements are separating. This will happen some times on older lenses. Have a look at pictures in this thread: http://www.l-camera-forum.com/leica-forum/leica-collectors-historica/80747-slightly-ot-contarex-lens-refurbishment.html#post844866 Regardless you should ask for your money back.
