I bought this lens "for parts only" thinking I could fix the aperture control easily. However, I was wrong. I took the lens apart and re-assemble it. Now the lens does not focus properly and it would not zoom to 28mm.
So, if you are handy fixing lens, it is yours for free.
The optics is in average conditions. There are some dents and scratch marks, and some dusts inside as expected. The rear lens element is not bad. It still takes pictures at 85mm within 1 m.
I have the repair manuals as well if you need them. It was too complex for me.
Lesson learned for me. Zoom lenses are far too complex to play around with. Never mess with the focusing helicoid. |
