    Dear Richard
    Greetings fromSingapore. Fantastic content.

    Your website has helped me make some repairs and cleaning of my AI Nikkor lenses. I have switched since last year to all AiS lenses.
    I have one 50mm non-Ai Lenses (plan to convert Really soon); One 50mm f1.4 Ais; And one 24 to 70mm f3.5 – 5.6 AiS.

    This has also helped me to improve more on my photography Techniques. Previously relaying on all the modern Nikkor lenses, the auto focus and other features has made me lazy and lose the basics of what really photography is about -“the art of composition through light and shadow”

    Since going back to the beautiful and manual simplicity of AiS lenses, I have improved more on my skills and look forward to learning more.
    Your website has helped me in the care and maintainance of these wonderful lenses.

    Thank you very much
    Look forward to more from you

    Best regards Sean R.

      Hello, Sean!
      Glad that you liked it. I missed Singapore, I used to live in Paya Lebar.

      Another durian started his repair blog so you may want to check that out. I must admit that I have not read everything there because I am too busy but I am sure that it is worth a look.

      Before you convert your 50, please take a look at the Ai conversion guides that I wrote to decide which one will work for you. Ric.

    Hi Richard,
    I’m wondering if you’ve had any experience working on nikons 300mm 2.8 AI? I’ve got one coming that has stuck aperture blades and am looking for some info on a repair.

      Sorry, but I do not have anything for that at the moment. That is too exotic for me. If I find one on the junk shop for a reasonable price I might consider it. Larger lenses are a pain to dismantle as they require a considerable amount of wrist strength. Ric.

        thanks for the response, Rick! I should have messaged you on Nikongear but didn’t remember you were a member there.

        take care!

    Hello Richard
    I stumbled across your website today and I find it to be wonderful. It has certainly encouraged me to attempt to clean the fungus from my Nikkor 80-200 f4.5 lens. Do you have any guides planned for the Nikkor 28-85mm AIS or the 300mm f4.5 IF-ED?
    After managing to keep my lenses from from fungus in Hong Kong for 17 years I now find, here in France, I have acquired it. Perhaps I am eating too much French cheese.

    Any help would be gratefully appreciated.

      Hello, Christopher!
      Glad you liked the site! As for the lenses that you mentioned, unfortunately I do not any guides for those as they are currently out of mu budget. How bad is the fungus and where are they? Ric.

    Dear Ric
    I am very appreciative that you took the time to reply. The mold on the Nikkor 300mm is on an internal element probably the middle lens group. For the moment it isn’t too bad. I might have to swallow the pill and pay for it to be cleaned. Many thanks. Christopher

      Thanks, Mike! I appreciate the offer but I do not know how much the shipping will be. They are very good cameras! Is it because the contacts were dirty? Ric.

    Hi Richard,
    Thank you for this great blog and excellent information. I have a Nikkor AF 55mm macro (2.8) lens that is almost 30 years old. It is a great lens and I want to use it for copy stand work on a D70. Trouble is, the outer (plastic) focusing ring has snapped in 3 pieces. Sent it to Nikon and they say it is too old and parts not available. Took it to a repair shop in NYC and was told the same thing. So, this is my last shot at a repair. Do you have any advice on where I might find this simple part? Looks like it just snaps on… Any help you can provide will be greatly appreciated!

      Hello, Adell!
      I am not sure about which focusing ring you are referring to because the focusing ring of this lens is metal. it this the one that has the numbers or is this the one further front? Have you opened and seen what’s broken? This doesn’t easily get broken as it will bend first. I believe that the screws might have been loose. Ric.

    Hi Richard,

    I recently purchased a Nikon 24mm PC-E lens. The previous owner neglected to tell me that he modified it to have the tilt and shift functions on the same axis. I want to put the lens back in its default configuration, but 3 of the 4 screws I need to remove are stripped. Would you be able to give me more information about the micro screw extractor you use? The heads of these screws appear to be 2.5-3mm. The only micro extractor I can find is the Micro Grabit by Alden. Thanks.

      Have you read my screws article? There is a writeup there about how to use the extractor. There are some sellers online but you have to buy the exact one that I use because this is the smallest one available. Ric.

    Richard, do you have any knowledge about Nikon 300mm 2.8 lenses? I have the first version AF-s and need to remove the tripod collar due to it sticking. It seems very simple after looking at the repair manual, only 6 screws and it should slide off. My problem is that I am not able to get off the “tripod socket retainer ring”. Would you be able to assist in any way? I can provide photos and a copy of the manual and parts list.

    I am trying to remove the “Tripod socket retainer ring” on my 300 2.8. The repair manual seems to show 3 set screws to remove although I only can find one. My goal is to remove the Tripod socket and clean since it had started to stick. What tools would i need to remove this screw. I can provide a copy of the repair manual and parts list.

      Hello, Chris!
      Great to hear from you! It is good to know that you got rid of the bayonet screws with ease!

      The set secrews may be hidden from view and you may have to rotate the collar to find it. I do not know,really. I do not have that lens in front of me so I cannot make an accurate assessment. You can email me the manual at but please tell me which page that thing is shown. Thanks!
