Nikon Nikkor 35mm f/2D : disassembly and aperture blades cleaning

In this video, I disassemble the excellent Nikon Nikkor 35mm f/2D to access and clean the aperture blades. They got a bit of oil.

Merci, j'ai pu réparer un 35mm grâce à votre vidéo !

Content que ma vidéo vous aie été utile. La meilleure façon de dire merci c'est d'en parler à tous vos connaissances de la chaîne, et bien sûr s'abonner et "liker"

Used your video to clean my 35mm, thanks!

[@diyextravaganza]

Gu rear, hope everything went smoothly!

[@monkeyfinger7949]

The problem that you had with the aperture blades not opening all the way is the exact same problem as I am having trying to work on a Nikkor 35-70mm lens. It's driving me nuts trying to find out why it's not opening all the way. I have reassembled it 5 times! I wish you had filmed the fix for that issue.

[@diyextravaganza]

A 35-70 Ais? I have one waiting for fix an oily diaphragm. Normally, you have some play on the holes where the diaphragm is fixed, so you can move it by a few degrees, with that degree of freedom, you can set it to open or close. Best.

Спасибо! Почистил!

Glad the tutorial was helpful for you my friend. Do not forget to share!

Has tenido mucha suerte de poder quitar el aro frontal tan fácilmente. No siempre es así..

@@rahandulcaspatal5276 Lo se, para facilitar la tarea, utilizo cinta pegante doble cara, así obtienes buena adherencia. Saludos.

[@Austographer]

Hi! Thanks for the awesome video. I think I'll give this a go myself. The only question I have is what kind of alcohol did you use to remove the oil? Is it rubbing alcohol? Isobutyl alcohol? Thanks for the help!

[@Austographer]

Also, did you assemble the aperture blades incorrectly in the video? (hence why you made the comment to assemble them counter-clockwise)

[@diyextravaganza]

Most probably, this an old video and I had less experience. But yes, most Nikon diaphragms assemble counterclockwise. Best.

[@diyextravaganza]

Btw, lighter fluid, gasoline or bbq gas work better than alcohol in such case. Best.

[@ALinsdau]

How did you loosen the front piece with the white ink writing? The front on the one I have doesn't loosen.

[@diyextravaganza]

Sometimes it is tricky as it can slip on the thread, try using double sided tape between the ring and your tool. Cheers.

Est ce que vous savez comment régler le map sur le même objectif car l'infini est décalé sur le mien très bon tuto merci 👍

[@diyextravaganza]

Bonjour, oui, je sais, mais je ne saurais pas vous dire la procédure exacte car je n'ai pas de 35 f/2 disponible de suite. Votre objectif a été démonté ? Salutations

[@edmak448]

Bonjour merci pour votre réponse rapide j'ai acheté il y a quelques mois cet objectif j'ai réussi nettoyer les larmes en regardant votre tuto il était déjà décalé car il sortait un peu trop mise au point j'ai pas réussi trouver ni tuto ni en mode emploi préparation pour remettre en place merci pour votre aide Salutations

[@diyextravaganza]

@@edmak448 il a peut être été démonté avant. Il me semble que la bague de mise au point est bloqué sur 3 vis, on peut les dévisser et ajuster sans tout démonter. J'ai un tuto pour le 24mm AFD, il me semble que je fais ce réglage, sinon pour le 50mm 1.4AF, je l'ai fait aussi. Salutations.

[@epaitor]

Hey, thanks for the video! I am trying to see if it is possible to dampen the focus ring of this AF lens, as I want to use it for video and the rotation feels too light for my taste. Is there any way of doing this? Tanks in advance!

[@diyextravaganza]

Hi, you can use a stiffer grease. The type of grease in this type of lenses is of low friction. You can try a Molykote ws2 which is a bit more creamy than the standard one. I have use it to stiffen the focus of 1.2 lenses that I like for accuracy. Cheers.

[@epaitor]

Cool @@diyextravaganza ! And where exactly should I apply the grease? I saw how you disassembled to expose the blades but but I can't figure out where I would apply the grease. Thanks in advance!

[@diyextravaganza]

@@epaitor well, to do that, you'll need to access the focusing part, but that's a bit more tricky. I don't think I have a video showing that for this specific lens. The assembly of these series of lenses is fairly common to all of them. You can take a look on a video I have showing the entire disassembly of a 24mm f2.8 AF. Cheers.

[@fotoportillo6991]

how did yuu open it? I try to open mine but I cant flip the lid.

[@diyextravaganza]

That one is indeed tricky, try using double side tape and something round and bit soft behind. Cheers.

[@zaeemology1219]

Scary video for some photographers and videographers😂

[@diyextravaganza]

Lol

[@Alexander84001]

Please answer me. I cleaned the aperture blades and assembled the lens. Now the aperture blades quickly take up their position during the shot, but the photos are still too bright. Could I have assembled incorrectly? I mean, the initial position (fully open aperture) turned out to be not 2.0, but wider. And because of this, during the snapshot, the aperture does not open as it should

[@diyextravaganza]

Hi, I do try to answer to everyone. Let's trace this together, answer these questions so I can understand what's going on: (1) You cleaned the blades and install back in position? (2) When you move by hand the aperture ring, they do move as they should? (3) When you move the aperture lever (the moving part on bayonet) they open and close quickly?. (4) When you move aperture ring manually, the diaphragm is fully open at f2, or it is fully open before?

[@Alexander84001]

@@diyextravaganza 1 yes 2 yes 3 yes 4 yes. When aperture ring is on 2.0 hole is round, when ring is on 2.8 - the hole is have angles kzbin.info/www/bejne/q6bIm4VobbSmsLcsi=pPF82jtmFmRLZUxG

[@diyextravaganza]

@@Alexander84001 Hi, in your video everything seems to be ok and well assembled. So, in my experience, two things are possible, first, the spring of the diaphragm is stronger than the original one (hat that issue on a 35mm 1.4) or you must better adjust the diaphragm so you get the stops right (as here kzbin.info/www/bejne/o3emh5lsarmLntk), when you're at f/2, the blades just barely disappear on the rim. Best regards and hope this helps.

[@Alexander84001]

​​​@@diyextravaganzaHi, I fixed my lens today! It was assembled incorrectly. When i assembled aperture module and put it into lens body I did it a little bit incorrect. The position of aperture module inside lens body may be a little bit changed by rotation (only 1-2 degrees). And when I rotated it thе aperture area is changed a little. I choose position when I may see the edges of aperture blades, but they are not in picture. Now exposure with this lens is correct. Thank you for your help!🙏
