This section introduces disassembly and cleaning of old lenses and cameras and shooting with old lenses attached to digital mirrorless cameras.
I also like outdoor hobbies such as sea fishing and camping, so I plan to distribute them too.
Thank you.

YASHICA Auto YASHINON 5cm F2 Disassembly and Cleaning Video.
Tomioka Optics delivered lenses to major manufacturers such as Yashica and Ricoh by OEM supply.
Probably for decades, I got the Yashica Auto Yashinon 5cmF2 (the lens is Tomioka Kogaku), which used to sleep in a corner of a room without being used.
This is a video of disassembling and cleaning that lens.
(There are also sample shots taken around my home)
Tomioka Optics lenses are very popular because of their wonderful depiction power, even after decades.
富岡光学は、ヤシカやリコーなどの大手メーカーへOEM供給でレンズを納入していました。
おそらく何十年もの間、使用されることもなく汚れたまま部屋の片隅で眠っていた、ヤシカオートヤシノン5cmF2(レンズは富岡光学)を入手しました。
これは、そのレンズを分解清掃した時の動画です。

Why can't the rear be disassembled?
Do you have to be careful of radiation when opening these lenses? Or is it not a problem because repairing is a rare occasion?
Have you try disassembling this lens with different serial number , start with 100xxx ?
Bravo!
Many thanks for this lovely video abouth the cleaning and what you need to do. For me it's clear that I do not want to dismantle the camera that far just to have a clear viewfinder. I had already cleaned some parts and bought a bnwfilm this afternoon so i will load the film in the camera and start shooting tomorrow.
Great video, thank you!
このビデオを作成していただきありがとうございます。 同様の修理をTakumar 100mmマクロレンズにも行う必要があります。 いくつかのツールを購入する必要がありますが、あなたのビデオを見て、より自信が持てるようになりました。
Any example flare for this lens ?
Very helpful, thank you for posting
Need more videos like this, teach me lots. Thanks.
Thank you for this video .I use contact adesive i repair of camera and lenses .
good
Great job! Thank you for the video.
Hi Tomoo Thank you for sharing this video but there is a part of it where you are showing how to remove the front element that is not the correct way to remove it. The part where you are forcing the front element out by twisting it and pulling it out is not correct. Please see below message from NigelR99 and my answer to his message. I think it would be good to update the video to show the correct way to remove the from elements. I made quite a mess of the threads on my lens following your instruction to force the font section out by twisting and pulling it out. From NigelR99 Remove the rubber grip and there are three hidden screws, undo them and the lens hood and name ring assembly remove. No need to force things..... the front lens element set wasn't designed to be forced out! My reply to NigelR99 Ricky 1954 Thanks for pointing that out Nigel. I was really struggling with that part. The forcing in and out of that section also damages the thread on both the internal and external lens holder section. Never seemed right to me that Pentax would design a lens that you had to force the elements out against the threads. As soon as I removed the lens rubber and the 3 tiny screws you mentioned it came apart easily and was very easy to remove the lens section.
Hi there. Thanks for sharing. Your videos are wonderful. I have the same lens to clean but even with proper rubber lens tools I can seem to be able to get the front retaining ring to unscrew. Can you let me know how you removed the front lens retaining ring ?.
warm it with a hair dryer to unstick it
do you clean the inside body too since mold can be everywhere but seen only on the glass. Normally zooms are too complex to clean but this one is not bad.
How long do you let elements sit in HP? Too much will eat up the coatings so its important to know. Thank you

Can you explain me how to dismantle the Om1 to repair the lock up mirror switch lever? Thanks a lot
Hi, My name is Trung Do and I am from the United States. Do you apply any type of grease to the threads on this lens? If so what kind of grease? If you can show a picture so that I can order from the USA that would be most helpful. In Japan I am sure you have access to much more cleaning and repair supplies than in The USA because most people here prefer to buy new then repair anything.
Really interesting. I have the 3,5 variant. It was dropped to the floor and now the zoomring is really thight in one spot. Any suggestions or advice?
Hello, I am going to travel to Japan soon and I wanted to know where you recommend I buy analog cameras. I was thinking of going to thrift stores, but if you have a place to recommend I would appreciate it. よろしくおねがいします。
ผมชอบการซ่อมกล้องถ่ายรูปและเลนส์มากครับ (เพราะผมเป็นช่างซ่อมกล้องโปราณ)
Very nice and educational your videos, thanks. One question; is this yashinon 5cm f2 6elements in 4 groups, and similar to Disassembly than yashinon auto 5,5 1.8 ?
This video was really informative! Is the disassembly process similar for the f/3.6 variant?
Thanks for sharing this nice video...really appreciate your good effort. Keep it up. All the best.
Great video, Will be a big help to me as I've just bought one of these and I know it will need a clean.. Thankyou : )
Nice video. Looking forward for the next one. Thanks
Great video!! Thank you sir :)

Can't see what he is doing. Hand and arm in front of lens and camera.
hi, i have same lens but aperture blades are stuck. Could you show how to fix?

Excellent video.
動画ありがとうございます。 一つ質問ですが、ファインダの掃除と露出計の作動に関係ありますか?私のOM-1の露出計が実際より暗く測定していますが、ファインダの掃除がそれを正常に戻されますか??
How to repair lens hood dampening (freely siding forward when lens is pointed down)?
Wow, excelent job.
wonderful job
hurui OM1no yuzatoshite benkyoni narimashita arikatogozaimasu!
i ve a problem with my takumar, is the same of your model.. the ring of the distance, the one connected to the focus ring, it is not more joined with the focus ring.. Do you know how are they joint together?
Stupid movie, first go and learn how to really do it
Very helpful! Ive managed to clean the first elements, but I cant open the back of the lens, how did you remove the mount?
Hi, great video thank you! Any idea if 6% would be good or too strong? Thanks Joe
Just dilute 1:1 with distilled water and you have 3%
Thanks
Amazing work! You are the smc lens doctor 🙂 Did you learn simply by doing?
Great stuff! Thankyou! 🙂
May I know which solutions to use any kind of lens glass? And also to clear the outer surface of the lens?
