Bought this off of ebay supposedly in great condition, and being ebay it obviously wasn't and the seller was a total naughty word.
So this lens "in great condition" actually had very stiff focusing, numerous small scratches to the front elements, heavy marks to the coating on the rear element, a dodgy zoom mechanism, didn't focus to infinity, and had obviously been at least partially stripped before and was cosmetically far from great.
So not trusting thet**t seller enough to return it to them that left only one option, fix it.
first up was to take it to bits
If your interested the bits are:
1. Front element section (2 chunky bits of glass)
2. One touch ring for zoom and focus
3. Barrel that houses the zoom mechanism
4. part of the zoom mechanism
5. The focusing tube which houses no.1 and screws onto no.3
6. cap full of screws
7. the rear inner tube with aperture mechanism and rear elements, all one unit
8. zoom mechanism, goes inside no.3
9. metal cover strip that goes over the slot on no.2
10. couples the aperture to the aperture ring
11. aperture ring
12. mount
13. zoom element, goes inside no.8
14. another cap of screws
15. various covers with markings on for zoom and focusing
while in bits I cleaned it all, re-lubed the focusing threads then put it back together, glad I had another copy to check as very nearly put no.13 in upside down which would have been annoying to say the least
and here it is back in one piece, not perfect as b****r all i can do about the glass but the zoom works perfectly, infinity focus is good and focusing is better though not perfect as I think one of the tubes has been squished slightly as it is a bit stiff at the tele end..
Surprisingly iq seems near identical to my other copy despite the glass issues so all in all a successful operation
