Just posted! I hope that you enjoy reading this. This is probably the best deal in telephoto lenses today!

Thanks Richard, very thorough repair guide!

thanks, this took me longer than usual 
this is an easy lens to fix. even by a beginner. but there are a few gotchas

[ArendV]

Thanks Richard, I have no need to dismantle mine yet I think.  And I agree it is a good deal and performs well wide open, at least on my Sony A7

[Erik Lund]

Those look absolutely beautiful!

you are welcome! that looks mint 

now that we now that the focusing ring is only being held by a few small screws, we need to be careful on how much force we use to turn the focus ring

Actually mine is an early multicoated Q-C

And you probably all know this episode 48 of NIKKOR - The Thousands and one Nights on the Nikkor-Q Auto 200mm f/4, but just in case.

Stunning shots, Arend.  The white one is very delicate.

The 200 mm f/4 Nikkor Q has some appeal for use in UV as well. Demonstrated here with a Phalaenopsis (Moth orchid) and Japanese characters "written" with sunblocking lotion. Hopefully my son had studied his Japanese diligently (he wrote this). Must have learnt something of the language after living in the country for 18 months. Or so I hope as I paid the tuition fees !!

Do note only the first version without the 'C' designation should be used. The last QC will work - sort of - however, its UV sensitivity and UV sharpness are poor.

Arend, I have the same version and it performs admirably either on FX (24MP), DX (16MP) or even m4/3 (16 and 20MP).

Bjørn, according to "Thousand-one night", the first versions happended to use glasses that transmits blue too well, which would suggest the reason for the good transmission of UV.

Very understandable written and illustrated, Richard. Compliments.

[ArendV]

Akira, indeed I just noticed from another thread you have exactly the same lens.

Richard, Erik & John, thanks for your comments. The flowers (artificial and real) were my test objects at home when trying non AI lenses on my A7 for the first time.

Thanks, John! this took me a long time to write. 

from now on i am going to follow this format for all of my tear-downs. i hope the big pictures do not annoy you, it was requested by a lot of readers....

not thinking of doing any UV work, but i am curious about the lens' performance on IR. i am still interested in doing IR work in the future

This topic reminds me of my young days, when I used to dismantle my rich cousin's toys to see how they were inside.
Most often there were parts left when I tried to assemble them.
It used to make my aunt crazy.
My cousin didn't care as much as her.
