juergen Posted October 7, 2010 Share #2 Posted October 7, 2010 Hard to tell, but depending on the conditions under which the lens has been stored over the last three years, it could be fungus. Jürgen Link to post Share on other sites More sharing options...
earleygallery Posted October 7, 2010 Share #3 Posted October 7, 2010 It doesn't look like fungus to me. Have you tried cleaning the lens surfaces (front and rear) with some safe cleaning fluid or one of those moist lens wipes? If it really is inside the lens, the first image looks like dust spots, but the second image does appear fluid like - maybe oil from the aperture blades but it would be an excessive case. Try the cleaning first, if not send it off for a CLA. Link to post Share on other sites More sharing options...
PasMichiel Posted October 7, 2010 Share #4 Posted October 7, 2010 can be separation of the coating. Link to post Share on other sites More sharing options...
k_g_wolf ✝ Posted October 7, 2010 Share #5 Posted October 7, 2010 Weird, never seen this in a lens. Appears to me like a pattern of condensation drops or an overspill of lubricants. Best GEORG Link to post Share on other sites More sharing options...

Best GEORG indeed condensation. So try to wipe it! Hoping the coating is not damaged. Link to post Share on other sites More sharing options...
masjah Posted October 8, 2010 Share #7 Posted October 8, 2010 Advertisement (gone after registration) Stefan Can you confirm that the deposits are on the outer surface(s) of the lens? If so, I also think that it might be the residue of dried-off condensation droplets. Under what conditions was the lens stored though? I agree with James, try cleaning the external surfaces; the Carl Zeiss lens cleaning kit is very good. Link to post Share on other sites More sharing options...
drstefanlenz Posted October 8, 2010 Author Share #8 Posted October 8, 2010 hi, it is inside the lens and it is no fungus, but sth liquid. leica said maybe oil from the iris diaphragm. it was stored all the time in the original case, inside living room area with a lot of others lenses. it cant be water, should have evaporated long ago. i will send it in soon but i hope they will not make me pay a lot for i think even when garantee is over this should never happen. the lens was at solms with the M8 in 2007 for 6bit coding. what seems strange that is happens after years.. well, i will see, thanx for the comments! stefan Link to post Share on other sites More sharing options...
adan Posted October 8, 2010 Share #9 Posted October 8, 2010 "what seems strange that is happens after years.. ' Not strange - it takes years for oil to evaporate and redeposit on the glass. Personally, if I have a lens that sits unused for 3 years (or even 3 months) I start wondering why I have money tied up in it and sell it for something with more use potential.
