I've now changed my own lens line up and so I have some old filters which I won't need any more. I have a Canon 77mm Circular Polariser + 3 x Canon 77mm Protect filters. All have been used and show some marks on the glass but these are only marks on the coatings (no actual scratches as such, just rubs or similar) which don't affect the images but do make the filters less than perfect. They are ideal for using in boats where they will protect against salt spray getting onto the front lens elements (which is what I've used them for). I'm open to offers on these. Send me a PM if interested (I'm in the UK).
