I tried lens tissues, the system above, in fact everything I could think of. Nothing worked. Then on a whim, I bought one of those (then new) "magic" micro-fibre cleaning cloths that you use dry. I breathed on the lens and gave it a gentle wipe. The smudge was gone! My cloth was from Pentax, but they're all over under various names. Sizes & prices vary. Best $10 I ever spent! Side benefit: no risk of any liquid seeping into the lens' interior. And when the cloth is dirty, you throw it in the wash! ----------- David Young: youngs@IslandNet.com
