Put it back together. Good luck. Good luck for sure! There is no way I would ever recommend anyone taking their lenses apart. There are issues of centering, and minor adjustments and what kind of lubrication might be used, and excess being applied. Leica's lenses are given a minimal amount of lubrication. Too much attracts dust inside, and it also ends up making it sloppy when the lens gets broken in. I will take apart my comptuer and mess with the innards, but NEVER a lens. That's why we pay them the big bucks! To make sure they go together right. =========== Eric Welch Grants Pass, OR A husband said to his wife, "No, I don't hate your relatives.
