MIR-1 2.8/37 focus repair tutorial 

You're welcome!

You're welocme!

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!

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

@@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

maybe in the future....

difficult to say... If you follow tutorial step by step there will be no issues at all....

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.

1 or 2 mm, i do not remember exactly

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

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

never mind, the ring was upside down : )

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 :-)

no, i'm not familiar with this lens

not yet, but will come soon

Thanks for your useful video!

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

Actually i do not repair third party lenses, sorry

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.

ciatim-201

1,1mm i guess

да он похоже поздно понял что корявыми ручоноками своими херню замаздрячил и решил не переснимать :-)
