Just picked up a kit today, basically a 55mm 2.8 Micro Nikkor was thrown in due to its rough shape. The lens has all kinds of dust on the inside, probably mixed with fungus and who knows what else. The aperture mechanism and ring work, but the focus ring is incredibly hard to turn.
Seeing as how this lens is already a total loss, it's only uphill from here! Any suggestions on solutions or methods to get this thing cleaned up? I'd guess the coatings are already shot, so all ideas welcome
