Even though it's the least expensive of the ML macros, I was quite excited when I managed to get this lens (mounted on an FR-1) for 45 euros on ebay last week.
However, my enthusiasm waned considerably when the lot arrived yesterday; both camera and lens were unspeakably dirty and grimy and reeked strongly of stale cigarette smoke. The lens had two nasty dents in the filter ring, but I had known this before and dismissed it as quite irrelevant for my purposes. What the seller did not tell me was that the aperture blades were completely stuck in wide-open position...

So I took the lens apart up to the point shown in the second image and then decided not to proceed any further but to put the whole thing into a marmalade jar and bathe it in lighter fluid so that both sides of the blades were fully immersed. When the aperture was clean and snappy again, I put a tiny amount of grease on the helicoid until that grinding metallic sound stopped and it moved smoothly again.
Seems to be working fine now so I think I can make some first tests with my S2 tomorrow. There are a couple of frames left on the film I used for the Tokina 135mm so there's going to be some interesting (if slightly unfair) competition...
