Thanks for posting this - my 85mm 1.8d was dropped yesterday (by a well meaning friend) and the focus ring became tight, so much that my camera couldn't drive it anymore. I used your video for reference on how to remove the front retaining ring and lens element and I used a cloth and some pliers to bend the ring back out. Unfortunately, I left some dust inside so I'll have to take it apart again once I have the proper tools to clean out the dust. But thanks again!
Update: The AF mechanism was very slightly stuck from the fall, enough to block the AF motor but easily released by turning the AF screw gently with a screwdriver. Now fully working!
Glad i found this video. I have a nikkor 85mm 1.8g afs that has dried water spots behind the rear lens element. Do you have a video that shows how to remove the front lens only? I do not want to mess with the rear at all
At 10:40 after you have removed the front element, is it possible to separate the front glass from that housing ? I have mold in between those two lenses that together creating the front element. I have study them closely but couldn't find a way to separate them, are they glued to the housing ? Many thanks in advance for your help
Thank you for sharing all of your great videos! I kind of like that there is no sound I you write everything down so we can read it, it's kind of like watching a silent movies where you have to read all of the dialogue, but in a good way :)
thanks for your reply,i have the 85mm 1.4d which at present works fine,good to know for the future as lenses are silly prices but then again quality always costs
Mikeno, good afternoon, im about to buy this lens with a little problem (but the price is GOOD). The lens doesnt turn to A, its currently on M and when you turn the focus ring it does nothing. The internal parts of that mechanism are metal? plastic? could they broke? Can you "manually" "lift" the section of the lens which runs the Autofocus and somehow make it stuck there? Thank you very much for your time!
Thanks for the video. All those delicate electronics and mechanical links makes me nervous. I have a manual focus Tokina lens (ATX 100-300 f4.0) that has a hazing on what looks like the second element from the front. What do you think, it seem like it would be easy, compare to what you did here on the back element. Will zoom lenses create problems disassembling due to the zooming mechanics? I probably would not want to go much beyond removing the front element, clean the second without taking it apart, then put the front element back.... Thanks again.
Good evening, Any ideas/tips on how to remove fungus which has grown in the front element ? Between the glass layers, couldn't seem to find a way to separate the glass pieces... many thanks !
I believe some elements are glued together. Fungus grows in that glue, making it impossible to clean without complete disassembly. Nikon offers that service, it is expensive www.nikonimgsupport.com/eu/BV_article?articleNo=000005459&configured=1&lang=en_GB&setRedirect=true
+ian b Yes, the lens is adjusted to be correct in the factory, but disassemble the lens for removing dust on the lens elements in this way, does not make any "out of alignment". I have make my check on focus and there is no problems.
It’s a very good video! It seems a very difficult procedure that I would never attempt by myself haha :) . But one thing is bothering me. You are rubbing the lens with a cloth. Not a very good idea . It certainly will leave the residue or traces of your rubbing, or even scratch the lens , moreover if your nails are long enough. It’s easy to scratch lens. The safest option would be lens pen with that Carbon tip which don’t leave any traces. And I would prefer to disassemble lens inside airtight box where no dust or microbes/spores can go in but yes not every one has such airtight specialized boxes
Hi, great video! I have a question tough, i just found very small bugs inside my lens (nikon 35mm 1.8G). Opening up the lens following these instructions (should be pretty similar) would mess up the focus or lens calibration? I found lots of people saying that opening a lens might do that, but i just want to know if it is possible to avoid if being very careful.
I have actually made 2 videos about that lens, the videos are with out any sound, that you can see here: 1. PART: ruclips.net/video/uoPdRNT03G0/видео.html and 2. PART : ruclips.net/video/EHUFXU4ttxU/видео.html
Hi there ! Thanks a lot for the great videos! I have an 85 1.4 Ais which has two retaining rings for the front element. i cannot loosen either.... Any ideas? Thanks!
Hi Dimitris Well, I do not have the 85mm 1.4 Ais (I will buy one some day...), but it look's like you have to take off the nameplate first and then the lens group from the front, I'm not shure, but maybe there is a small set screw on the side of the front tube..., or you maybe have to take off the rubber on the focus ring, and in that way find a little set screw to loosen. Maybe there also are some sticky tape on the focus ring that can be take off.... Just some ideas, hope it can help you. Cheers Kenneth
Thanks for the comment! It is actually easy to remove the name plate and the barrel, it has the typical plug on the side. That's how far I got. But the front group is very tight and there are two rings, one tightening the other. It is also difficult to get in from the back, I will need to make a special tool I guess, I see no other way... By the way, these CRC lenses are easy to reassemble, once you align the rear group focusing tab with the alignment screw and set the aperture to maximum f number, the whole assembly goes right in! Also, I am embarrassed that I own the lens and you don't, I was lucky enough to buy from an old photographer an F3HP, 50 1.2, 35 1.4 and 85 1.4 all for $300!
Hi Dimitris I had a problem with the front part of a lens, so I get to a kitchen equipment store and buy a glass "can opener" (it look's like a tool for taking off the oil filter on a car engine), it has a long rubber band and a handle so I could thighten the rubberband around the lens and unscrew it, it was very very thight but it came off "easy" with this tool. If you look into my video here, you will see the white tool I use to take off the front ring on this lens. Repair Ai-S Micro Nikkor 105mm 1:2.8s______PART 1__Motion Lapse film Yes, I have also observed the easy way of disassembled some manual lenses, that you discribe.

Well, sky650717 In this movie I use "Lighter Fluid" to ceaning the lens elements, it take's the oily film away, because it evaproates very fast and let the surface absolutly CLEAN... I'm NOT using oil to cleaning lens elements...., Hope it make's sence. Cheers Kenneth
Well, in my experience during many many lenses, I have always use Isopropylalcohol 99% or Lighter Fluid, and I had never had any problems with that AR coating. On the other hand, I have no idea how it will work on Flurit coated lenses...
Sorry but I don't have the testicles to do this to my fave lens. I am lucky that I have dust particles in the front elements. From what I heard, the rear elements are the ones to worry about.

Hi Stephen
Good to know that my film could help you :-)
Bought this exact model lens for cheap because it was dropped and the AF mechanism is damaged. Going to see if I can fix it. Thanks!

Большое спасибо.
(Excellent video tutorials!
Thank you very much.)

how you unscrewed the front element?

@mikeno62 what screwdriver do you use for the first small screw of the Front element ? I cant find one that small.
hi, is the same process in the 1.8D?
great video ,only one question are the lenses not set up in the factory to line up perfect ?
+ian b Yes, the lens is adjusted to be correct in the factory, but disassemble the lens for removing dust on the lens elements in this way, does not make any "out of alignment". I have make my check on focus and there is no problems.

Is the rear element supposed to be a little loose or my copy of the lens is faulty?
As I remember, it should sit tight, but there are maybe a loose retaining ring (just an idea).
It isn't easy but beatiful work
what do you charge for this ??

is this clearning liquid safe for AR coating ?
Well, in my experience during many many lenses, I have always use Isopropylalcohol 99% or Lighter Fluid, and I had never had any problems with that AR coating. On the other hand, I have no idea how it will work on Flurit coated lenses...
mikeno62 it doesn’t works well on Fuji lenses .... it will worn the coating off making the wavy appearance on the lens
@@Pentax67 petrol is very aggresive ,try it on skin , burn and is greese?!!_alcohol is OK
Great skills you have but god damn wish you talked us through it too! Please get a mic, get those skills out there better.
sir you are amazing

You are supposed to do that with your hands, silly
