    AF Nikkor ED 180mm f/2.8 - anyone ever dismantled?

    I took some indoor headshot portraits with my kit 24-120 f4 and was a little underwhelmed, and was also watching the "Angry Photographer" https://www.youtube.com/user/kathodosdotcom and he is always raving about the 180 f/2.8.

    Okay he raves about lots of things but the 180mm is cheap and seems perfect for headshots, and cheap screw focus F mount lenses is why I bought my D750 right?

    So I was thinking that maybe after Christmas when everyone has bought their new Z6/Z7 and starts selling off older screw focus lenses that one might come up cheap.

    Anyway I didn't need to wait because this morning I scored an AF variant of this for 158 described as "Condition is Used slight dust and fungus."

    Normally they go for about 250.

    I will warm up the screwdrivers for when it arrives.

    You might post your shot and ask for a critique, lighting can make a big difference.

    This site has a lot of information on older lens repair. Might be worth checking out.

    My understanding the reason you don't want a lens with fungus is it can actual etch the glass causing soft images even after cleaning.

    Thanks for the link. I haven't seen that before and it looks interesting.

    I repaired my AF-S VR 70-300 ( https://nikonites.com/telephoto/4377...autofocus.html ) and this old AF lens must be simpler than that to repair surely?

    One can hope.

    Also I have a good friend who lives just around the corner who repairs expensive watches. Maybe I will ask him to watch over my shoulder whilst I take this apart.

    AF Nikkor ED 180mm f/2.8 - anyone ever dismantled?
    The 180mm arrived yesterday, and I'm afraid that I was a bit disappointed. Out of two lenses bought on ebay, two have been f#$@d. The story of the first one is here https://nikonites.com/telephoto/4377...autofocus.html

    So. As the seller said, it had dust and fungus in it. What he didn't say is that the focus mechanism is broken. On autofocus it sometimes focus and sometimes doesn't and makes grinding noises. On manual focus the ring grinds and jams.

    So send it back "item not as described" or take it to bits and see what the problem is?

    So this is the lens now:-



    Well it has always my intention to take it apart and clean it anyway....

    Here is photo of when I found the problem:-


    You can seen that the cog is not well aligned which is when it jams and slips.

    Here is the actual part:-


    It took a lot of dismantling to get it out but I got there in the end.

    I will find someone with a lathe who can accurately drill a hole into the end of the shaft. I will find a drill of the right diameter and epoxy it in and then angle grind the drill off to the right length.

    Fortunately the teeth in the plastic focus cam that this turns seem to have survived.

    I have no idea which internal parts of this lens should be greased or with what grease?

    I think that lithium grease is safe on plastics and I have some.

    Anyone know?
