You can detach it without having to disassemble the whole thing. What you want to do is simply to press the tiny latch that fastens the plate after removing the focusing screen. The latch is located just behind the focusing screen latch. It takes only about five seconds if you have a good hand and a good tool. I am not a professional technician, but I have been taking pictures for more than 15 years, and in the meantime I came to know the some basics of the structure of my cameras. Now I am using three Cameras: Nikon F100, FA, Canon A-1. Thanks for your inquiries and suggestions.

Michael, thank you so much for the good info!

A quick question. Nikon F100. How is the part called that goes between the

focusing screen and the pentaprism. It is a kind of a transparent screen that

has 5 focusing marks on it. How can I get one? Mine has deep scratches and I

have to replace it. Don't worry. I know how to do the job. Thanks.

Dear Hartman and Ging,

 

Thanks for your kind answers. I found that the clinking sound has to do with the movement of the stopdown lever. I just want to add that when the aperture is at 2.8, the lever moves freely, and when it is at 32, the lever gets resilient and does not seem to move much, but I still hear "clinking," even when the lens on a camera. My other Nikon AIS lens (i.e.: 50mm and 135mm) don't have this kind of problem(?): in these lenses, the lever doesn't move at all at maximum aperture, and gets very resilient at minimum aperture.

 

Thanks.

 

Best,

I've recently purchased this lense. It is cosmetically and optically perfect,

but I hear a kind of small clinking noise when I shake the lense. Perhaps

something got loose internally. Is it normal for this lens? Otherwise, I have

to return it. Thanks.
