WOW 😮 I found this fascinating! I could watch you work all day. Thank you for this.
Very helpful and informative. Thanks. Would suggest you to include a list of tools and materials for the repair in the description or in the video for beginners like me to prepare before we dip our heads on.
I have an amount of old rangefinders. I buy them at thrift stores, or on flee markets and stuff. I just have them for show, so I clean them till they look okay, but I don't care if they are in working order. Videos like these inspire me to do more than cleaning and also repair them. Must feel great to make an old instrument working again, and take photograpfs with it. Thanks for inspiring me, and, nice work man!!
Thank you for this! I was able to successfully fix a stuck shutter and aperture and even put it all back together without any parts remaining (lol!)
Thank you for you video. It enabled me to go onto the lens on my QL19 to free up both the aperture and shutter blades. 📷
Glad the video helped
Thanks for the video. I'm about to use my Canonet. Hopefully I won't need to actually open it up and everything works!. But good to know there's an option besides the trash bin. Great that you added links to the tools you used.
Hello, thank you very much for the "necessery evil" spanner trick you showed us, so I could successfully remove the lens of a very stucked Yashica Electro M5 !
The second lens element can be removed without marring any metal, I used a friction rubber tool with success. The trick was I flipped the camera on its face and pushed down firmly on the rubber tool which was kept from moving with my other hand, and simply turn left and you will feel the factory seal break.
Thanks for the tip. I will try that next time.
Excellent!
Goo removers tend to have oil in them though, so it’s good you followed up with lighter fuel.
This video is great! Thanks for sharing. And thanks for all the comment replies, too. I’m learning just as much with those. I just bought my first Canonet, and I’m going to try to free up a sticky aperture ring (the ring itself is gummed up, but the blades seem to move fine). Another thing I noticed with mine, though, is that the shutter really needs to be pressed down all the way to fire - it needs every bit of button travel before it will take a picture. Is this an easy fix/adjustment? Thanks again!

You can use a 1-1/4 inch hole saw with most of the teeth ground off as a tool to remove the front element. It fits right in the gap.
Thank you! I watched another video for half an hour and they never showed how to remove the front element
thank you for info. i dont know how to remove the inner lens, now my canonnet is fixed..
Awesome. Glad I could help.
This has been a great video to walk me through this process. I have everything functional again but as I'm putting it back together I'm not sure what ISO the camera was set at when I took it apart. Is there a way to tell what ISO the camera is set to so that I align the ring back in the correct position? Thanks!
The ISO dial doesn't have to be set back to the same position when you are putting it back together.
Thanks for the video but my aperture ring is still stuck, it can easily close but not open, even if i put fluid in both the lever and inside the lens, it still doesn't want to open, do you have any idea ???
Brilliant video. I just did this on a QL19. Shutter works now. Aperture will always close using aperture ring but won't reopen. I couldn't get to the mechanism like your video. QL19 quite different inside. Question is do I keep on cleaning blades and hope they open without me using tool or could there be a mechanical issue?
Keep cleaning them, it could take some time. It only takes a little bit of grime to make the blades stick. Once you get them clean, they should open and close easily. This is why the best practice is to remove them for cleaning. Of course, that takes a lot more effort. This method will work, but will take you some time. Good luck.
I haven't found a single video on the model QL-19 are the model 17 and 25 that same as the QL-19? Anyone know? Thank you
Hi new sub,I got the older QL and I can't get the first locking washer out, wish I'd seen this vid first, I tried using lighter fluid through the self timer vent but I think I flooded it, it worked for awhile but I had used isopropyl alcohol first and I think it's stuck again once it dried, do you do repairs at all for these, it seems everything works except the shutter and aperture is stuck again.. Thanks
You really need to get in there to clean it out. Like I mentioned, the "proper" way is to remove the blades, soak them and clean them. That being said, this method works too. Be patient and take your time if you attempt to do it yourself. The 1st ring is soft, thin metal. Be VERY careful with it.
My shutter blades in front do not open after numerous cleanings. Shutter blades in back seem to work ok. Keep cleaning or do you think it's something else?
Hi, I have a 'New Canonet 28' from 1971 however there's a glass between the front lens and the shutter but I can't figure out how to get it out, seems to be retained by the focusing system assembly. Someone suggested taking the whole lens/shutter assembly out, do you know anything about this specific model? Thanks in advance for your help, love your videos!
Taking out the whole lens assembly is the best way to get to both sides of the shutter. I never worked on a Canonet 28, but here is a link to the service manual. I hope this helps.

Le new 28 est très différent les deux lames servent d'obturateur et diafragme en même temps je n'ai jamais vu de gommage sur ce type d'obturateur
I don't have the rubber tool and can't leave the second front element. I wonder if it's easier to clean the blades from the back side. Have you tried?
Hi. I found it harder to remove the rear lens because the space is really small.
Excellent video ... So ... to clarify ... proper aperture function is if the Aperature is like F/16 and you open it up to F/1.7 ... it will not and should not open until the shutter lever is cocked back? Mine does this and I've found this video thinking it was needing a cleaning or something. Would love to confirm this is proper function of this aperature. Thanks!
With the shutter cocked: the aperture should open and close as you adjust it. When the shutter in not cocked: the aperture will close but will not open until you cock the shutter.
@@wrldwar3 Devon ... you made my day. That is exactly how mine operates. The shutter fires perfectly and the aperture just as you described. I have another that needs about everything you did in this video. It's all gummy. Thank you!
Can not get my ql17 “lock washer” off for the life of me. I have the same silver spanner set as you. Any tips?
Sometimes they are REALLY tight, but you need to be very gentle. They are made out of thin metal that it very soft. Check to see if the filter ring is bent. If it is bent, you will need to straighten it before you can remove the lock washer. Next, check to see if the grooves are clean. Any dirt or build up will make the ring stick. You can also try a VERY small amount of lighter fluid around the edge of the washer to help loosen anything that may be holding it. Let the camera sit lens down for a while so that any dirt will run out of the camera and not inside.
You can also try these tools instead of a spanner. Sometimes they work a lot better and you don't have to worry as much about scratching your camera.

The best advice I can give is to be patient. Take your time. Never rush or force anything. Sometimes leaving it for another day is the best thing to do. If you have a local camera repair shop, they may be willing to remove the ring for you for cheap or even free.
Good luck and I hope this helps.
Hello,are you know why if i set aperture to "Auto" , it won't "fire"? but if manual it can.
To use the auto mode, you need to have a battery in the camera, and the meter needs to be working. It won't fire if both things are not in place.
I'm working on my canonet now, and while I think i've loosened the blades sufficiently, when the aperture mechanism was gummed up, did you find that it was much easier to close the aperture than to open it? If so i'll know i just need to keep working it, but i'm worried that there's a larger mechanical issue behind it not opening very easily.
That is the drawback of doing it this way instead of the "real" way, which requires the whole camera to be disassembled. It only takes a very tiny bit of dirt/oil to make the shutter of aperture stick. Makes sure you dry up any cleaning fluid as best as you can.
This is amazing Devon. Do you accept customers?
I am not a professional. I only work on my cameras and share what I learn.
Hi Devon,
great video! I was looking for this as my shutter is stuck.
Couple questions:
1. You don't mention using any lubricant before reassembly. Is there a specific lube for the shutter and aperture?
2. Would opening up from the inside and cleaning the shutter and aperture from the inside worth doing? and any plans to make a video teaching how to open and access the shutter from the inside?
thank you!!
Hi,
The shutter and aperture blades should be clean and dry. There should be no lubricant on the blades.
Removing the lens assembly and completely cleaning both sets of blades is the "correct" way to clean them. This video is aimed at people looking to get there cameras working so they can enjoy shooting them. Also, with this method, there is less risk of messing something else up or reassembling the camera incorrectly. In my experience, it is not worth the extra effort unless cleaning the front side does not work.
I hope this helps.
I just bought a Minolta Hi-Matic 7sii and it's aperture blades refuse to open up in manual or auto, would the repair for that be similar to this?
The 7sii is a different setup. It may or may not be the issue.
I need to get mine fixed, sticky shutter and dials are super stiff
Whats your website or IG. I need a camera looked at boss.
Hi what battery should I get for the camera

I have a ql19 I would like restored is that something you can do
I'm not a professional camera repairman. I just share what I have learned online in hopes of helping other people. I only work on my own cameras and a few for friends. I wouldn't feel comfortable taking in someone's pride and joy.
Where are you located?
@@wrldwar3 no worries I’m located about a hour outside of Los Angeles
hi Devon, great video!!! recently bought the same camera, and have that issue. ive been trying to unstuck the second front lens element but its really tight, tried everything i could, even using lighter fluid to "soften" the threads but its been unsuccesfull. Any suggestions? tips? thanks in advance! great videos !!
There are spanner notches at the base of the lens. You will need a spanner that will fit or you can make one by grinding one down. The lens can be REALLY tight, so use a lot of care when trying to remove the lens because you can easily damage it. Hope this helps.
@@wrldwar3 yeah I've been trying with the little notches at the bottom. Today finally I got it. And yes, the lens IS REALLY tight!!!! But I got it. Thanks for the answer. My camera is already working great!! Thanks!! Last question haha is there any advice when reassembly the lens with the alignment OF those? Or you just screwed them on?
A couple drops of lighter fluid on the threads made all the difference for me
Please answer my question, what the name tool for unlock ring lens ??

@@wrldwar3 thank you so much broo
i have a problem when i use auto mode, the apperture only the wide open. no matter which speed i used, the apperture keep wide opened. would u give the information which part i have to fix it? thanks
What battery are you using?
I thought my canonet was broken when I first found it because it wouldnt fire on anything faster then 1/30th. I didnt realise thats because its shutter priority and wont fire if it can't meter for a wide enough apeture. I was testing in my lounge at night 😅
One advice, remove the strap when you work on a camera.
I'm confused because I thought this camera has 5 elements. Looks you only removed two? or am I misunderstanding what elements are?
There are 6 elements in 4 groups. The front lens has 2 groups and the rear lens has 2 groups. Each element is a piece of glass used to make the lens. Hope this helps.
What kind of battery does that use?
Wein MRB625 Cell 1.35v Zinc-Air Battery
I just bought a canonet ql17 and it looks in fairly good condition. Aperture is perfect and film advance works fine, but the shutter doesn't seem to open up. There is a little movement when I fire the release and I can advance the lever again but the blades won't open up. I can't see any gunk on the blades through the lens. Do you think opening it up and cleaning it would fix the issue or is it something else?
1st make sure the camera is not set to "A" on the speed dial. Try it at a few different speeds to see if the blades open. A tiny bit of dirt/oil can keep the shutter from opening.
@@wrldwar3 thanks for the reply!! I checked all the speeds and made sure the aperture was set correctly and no luck.
@@jaysehayes4746 probably needs to be cleaned. The camera has probably been sitting for awhile.
@@wrldwar3 thanks!!! I'll give it a try haha. I really like the videos. Thanks for your help. 😁
@@wrldwar3 thanks for the vid this rocks. I have my camera opened up (front and back elements) and cleaned for a good while using lighter fluid and a little bit of rubbing alcohol occasionally and I still have the problem where the shutter seems to wiggle but not open. I did notice in my cleaning from the back that eventually the aperture got unstuck lol but the shutter is so stubborn. Is there a chance something else is wrong at this point? Any tips or do I just keep going?
man, no WONDER repairs are bloody expensive. this looks like open heart surgery
The tools is very hard to find. Is there any link to buy the tools? Thank you sir..

How much does this process usually cost?
I think shops charge $75-$100 for a CLA.
Someone commented that there is someone that does it for $30.
I would not recommend doing it this way. You have to open it up and clean every blade and the housing otherwise you will just get more trouble later with oil on the lens and into all parts of the mechanism. I have seen this on several cameras.
Only problem for me is that I can't get the rest of the lens out no matter what I do 😭
Another video that just shows how to move the oil on shutter blades further into mechanism. Six months later it ends up stuck again.
The camera is still working. 3 years plus and counting. Maybe me and all the other people who have used this technique are just lucky 🤷🏿♂️.
"Necessary Evil" = WRONG TOOL.
Unfortunately there are way more people that own and want to shoot these cameras than can afford the proper tools or professional repair. So, the options are: Camera goes in the trash or they find a DIY on TH-cam and the camera gets fixed and enjoyed for years 🤷🏿♂️. This video is for the all those that watched and fixed their cameras, NOT FOR THOSE THAT COME AND LEAVE A COMMENT IN ALL CAPS AND DON'T MAKE A VIDEO SHOWING THE RIGHT TOOLS OR BETTER METHOD. But, thank you for watching and commenting as this will help more people find this video and fix their cameras with, you guessed it, the WRONG TOOL. 😁
@@wrldwar3 1: My comment wasn't in all caps, a sentence was.
2: Why would I make a new video when "Japan Vintage Camera" already made one?
