Thanks for the idea! I legit poured silicone into the threads just by removing the focus ring. It spins way too easily but I'm starting to like it that way.
I have an early 60's KMZ Mir 1. I'm having trouble getting the black ring off so I can access the helicoids for regressing. I've tried wd-40, but that doesn't loosen it. Should I throw this in rubbing alcohol to loosen the old grease? Also have lighter fluid to clean the old grease off
Great tutorial. I have just bought the same lens, but it has the addition of a cine focusing gear. I wondered if you might know why it won’t focus to infinity? I’m using the black version with an m42 adapter to fuji x rangefinder camera
@@RetroFotoHouse yes I thought that might be the issue too. It’s quite a good adapter though and my Helios lens works fine. K&F concept adapters are quite good I’ve had several of them and all work well. They are Chinese I guess though still
Thought I’d let you know I received my small m39-m42 converter adapter. If anyone wants to try the same thing here is my adapter stack. I know it’s a bit of a crazy modification, but it actually works and my focusing helicoid fixes the close focus problem 😀 Leica m-fuji x focusing helicoid adapter small metal m39 - leica m converter m39-m42 converter 7mm m42 macro tube
Sorry, I know this is an older video, but does anybody know why the entire focusing unit rotates? I'm having a similar issue Andrew Ryan and Peter Tar were having. If I tighten the retaining ring that has the 4 holes and 2 screws, neither the focus or iris turns. If I loosen it just a bit, everything rotates to the point the rear retaining ring comes off.
hello I followed this modification instructions and now the lens focuses to about 55 cm instead of 70cm but I lost infinity focus in the way that it gets past infinity and blurred again even if on the scale of the lens it reads ''infinity'' what could have I done wrong? (i adapt it to a sony a7 camera) also I noticed that you were mentioning a close focus of around 35 cm and I saw some sample images which shows way more bokeh than i seem to get. any advice?
Thank you for the video, can you make a part 2 on how to fix sloppy optical part and aperture plus focus ring? My copy is 1958 Brussels version, and needs a good cleaning and fixing to eliminate sloppiness. Please man help.
I followed the guide and everything went perfectly until the last step of the re-assembly. If I put on the ring and tighten it, the aperture and focus rings both stop moving completely. If I leave it looser and screw it in, the same happens. Do you have any idea what might have gone wrong?
Peter Tar Hey, I had what sounds like the same issue your having. What I had to do was back up to where all I had was the locked in helicoil. First put on you aperture scale. 16 to 16 markers. Like at 14:29 The thing I kept messing up was putting the focus ring on from the top you slide it from underneath the very bottom of the lens. When I kept trying to get that black ring set from the top I lined the screws and everything it kept sticking the aperture didn’t work at all. Try to slide the black ring with the single locking screw from the rearmost part of the focus assembly then find the locking hole then put your finger focus ring with the 3 set screws in set the aperture to 2.8 and the preset aperture to 2.8. Slide the lens block into the focus assembly and make sure your focused to infinity line up the 2.8 to the minimum 0.7 focus distance and tighten down the last locking ring.
Hi, This is a great video. I have an MIR-1B and I tried to open the first ring like you did using proper lens opening wrench. After removing 2 grub screws from the 4 holes (2 small 2 big) I tried to turn the ring anti-clockwise with a lot of force on my lens wrench but it still wont turn. Is it possible that they have glued it down in the factory?
Hi! No, no glue in the factory. Only 2 screws. Normally it has to come, unless somebody but a glue before lens came into your hands, but it is unlikely.
Retro Foto House hello, I bought a Mir 1B today but unfortunately it doesn't focus on my Samsung nx1000. It focuses to a distance of about 1M only, I am using a m42 -nx adapter. This adapter works fine with my Helios lens on the same camera. Do you think the lens is faulty? Or the adapter needs a micro adjustment? Thank you
Hi. I have a silver version where in place of the two screws you showed in the beginning are not slotted but conical shaped. Do you know what to do with those? I need to put the stopping screw for the focusing ring back as it came loose and got wedged between the aperture ring and the focusing ring. It happened with the previous owner.
Well, it's a bad news. I'm afraid only one solution is available for you-drill them out. And than tap a new thread for a new (slightly bigger in diameter) screws
No i don't. In all the cases- you'll need to get anoter one in for parts condition and get screws form it. I have a doubts that you'll be able to find those screws in other way...
@@RetroFotoHouse following an advice from Facebook I was able to get a screw from my local optician (is that the word in English? Where you buy your specs). It's not fully hidden, the screw head remains on top, but the thread did fit :-)
Thanks! I actualy have one with oil on the blades and sent it for cleaning, but the person doing it is having a hard time accessing the aperture system. He says that it was assembled with excessive pressure (at factory) and can't seem to open it. Do you have any toughts on this? Thank you once again. By the way, love your videos!

Ah, thanks for the video! Very helpful! Just cleaned my Mir 1 and it's as good as new!
Thank you! My Mir 1 has the focus ring very stiff.
thanks for the guide, I was able to regrease the helicoid without taking everything apart by using rubbing alcohol to clean up the hardened grease.
you're welcome
Thanks for the idea! I legit poured silicone into the threads just by removing the focus ring. It spins way too easily but I'm starting to like it that way.
Happy you've found this tutorial useful!
The video was of great help. I used the video to clean my example that just arrived.
Thank you!!
You're welcome!

Often chineese adapters are not tolerating needed distances, it results in infinity not reachable

Thank you so .... much for this easy guideline. Hope I could get my ebay crap fixed, it was incorrectly assembled in every way.
VERY HELP FULL THANKS
The aperture adjustment ring on my lens is very stiff. Do you have any instructions for cleaning and lubricating that ring?
No, i don't, unfortunately
Thank You very much

Hi!
Once i'll get a proper version that needs such service, i'll definitely make such tutorial
@@RetroFotoHouse thanks brother, i make you sure there are many people need that video. Thanks for helping us! highly appreciated! :)
Hello, Thanks for your video. Could you specify the brand of grease? Kind regards.
every lithium based grease will fit
Please help! Where to find a 1mm screw driver?! Smallest I can find anywhere is 1.4!
seek on aliexpress.com
hello hope you can make MIR 35mm F2 Nikon Mount disassembly and relube video, thank's
maybe in the future....
I have one of these lenses and it focuses way past infinity. How do I fix that?

If helios works with your adapter and mir-doesn't, it means that mir lens was open and reassebled in wrong way

1 or 2 mm, i do not remember exactly

never mind, the ring was upside down : )

Hello! Do you have any video about cleaning the Mir's aperture blades?
No, i don't. It is rarely needed
Thanks! I actualy have one with oil on the blades and sent it for cleaning, but the person doing it is having a hard time accessing the aperture system. He says that it was assembled with excessive pressure (at factory) and can't seem to open it. Do you have any toughts on this? Thank you once again. By the way, love your videos!
Hi! No, i don't, as i never needed to open aperture of this lens.
Do you have any video that talk about how to relubricate the zenitar-m 1.7 50 lens?
not yet, but will come soon
Thanks for your useful video!
So disappointed, I bought an early Mir 1 and the screw heads were rounded and I can’t access the helicoid :(
Hello. do you have pentacon electric 4/200 tele lens? wound you mind take a footage about that lens?
no, i'm not familiar with this lens

What size is the screw driver?
1,1mm i guess
yeahh !!! thanx a lot ! perfect !!

Can you do this to my lens?
Actually i do not repair third party lenses, sorry
Приветствую!) Вопросы по смазке. Циатим 201 - это рекомендованная заводом смазка? Чем ещё можно геликоид смазывать? Густая силиконовая смазка подойдёт для этого?
Здравствуйте
Циатим специально разрабатывалась для этих нужд. Насчет силиконовой-не знаю.
С ув.
селикон очень плох, пробовал все, и только циатим реально хорошь.
да брызни банального wd-40, посуши и пойдёт прекрасно
Я так и не понял зачем кольцо было установлено наоборот
да он похоже поздно понял что корявыми ручоноками своими херню замаздрячил и решил не переснимать :-)
