- This video is about assembling the Canon EF 24-105mm f/4L IS USM lens after the aperture flex cable has been replaced with a new one. This lens gave error messages at small apertures, and the aperture did not work at certain zoom ranges. This problem was caused by the broken aperture flex cable, so the lens was disassembled, the aperture flex cable was replaced with a new one, and in this video I'll show you how to assemble the lens.

This tutorial and the other two in this series saved me a trip to the repair shop and a large bill. Thank you!
Thank you for your comment, and I'm glad that my video was helpful!
You sir are amazing - I was able to fix it myself following your steps, but holy shit that was one of the hardest things I've ever done in my life. It took me 8 hours and was sweating all the time like crazy. Even though it worked out perfect I've almost failed couple times so here are my tips:
1. Some screws are really tight - get a good screwdriver and apply a lot of pressure when twisting. I fucked up few 3 screws because of cheap screwdriver and even had to drill out one of them. Luckily I had replacements.
2. Plastic knob at 25:46 is surprisingly fragile. I applied too much pressure to it and it broke. Had to super glue it back - no big deal.
3. Pay extra care when desoldering/soldering aperture flex cable. The connections seem like a normal pins but underneath they are just super thin wires (they look like wire directly from aperture motor). I almost ripped one of them out when pulling old flex
4. Get a organizer for screws and mark them with timestamps from disassembly video. It has been a huge help for me when assembling back. There are about 15 types of screws here.
Once again thank you!
Thank you for the feedback! I don't use organizer for the screws, but I place the lens parts and screws next to eachother on my table, so when I have to assemble the lens, I always know which screws or parts are the next.
Thank you so much for these videos. My 24-105 is all going again! Sent you a few euro via paypal.
Thank you for your comment and donation!
I usually never comment in TH-cam .... but this time it's important :) I really thank you so much for making these videos. They permit to save my Canon lens ... for very few money instead of sending it to Canon and have a reparation for more than 300 Euros ...
Every step is very well described and my lens is new again :D
Thank you so much !!!
Thank you for the feedback!
Thank you ! Got my 24-105 lens working all because of your clear and thoughtful 3 part video presentation. Awesome work !
I'm glad my videos helped!
Excellent, detailed video! It helped me a lot. I replaced the train myself. Saving $ 200. Thank you very much!
You're welcome!
Thank you. Totally absorbing. Well paced and a clear commentary. You make it look effortless.
At 24 mins in, instead of placing the focussing element in the front barrel, position it correctly in the zoom barrel and then carefully slide the whole tube into the front end of the focus barrel, being careful not to trap the 2 flex cables. It will be easier to line up the focussing peg and key if the large front lens element is removed.
Otherwise, I have found your video very clear and helpful.
Thanks

Thank you for the tip, I'll try it next time!
Thanks for helping rescue my lens! Followed the steps and works like a charm again!
Seriously, unless you are very experienced just don't attempt this, it is an absolute nightmare and so many of the parts are extremely fragile and very easy to break, even when taking extreme caution! These tutorials are very thorough, but this man is a professional and this is not as easy as it looks!
Thank you for your comment!
Thanks a lot! Followed your instructions and my lens is back!
Thanks a lot! I fixed my lens using these instructions. :-) However, you make it look so much easier than it is. I would generally not recommend people to do this themselves but instead hire a professional like you.
It is very easy to do... if you do it the 5th time! :)
Thanku for this knowledge ❤
My pleasure!
Thank you sir. Awesome video, I recommend to everyone
So nice of you
Hola Ingeniero...muy profesional el vídeo.. excelente..!!!
Thank you so much for your effort and work
You're welcome, I'm glad that you liked my video!
Gracias, muy buena información.
Thank you for your comment, I'm glad my video has helped you!
I Just fixed my lens following your video!! It was really helpful thank you 🤘 btw canon was asking me 700$ to fix this 🤦😅 cost me 60$ with the tools 👌😂
I'm glad I could help.
Strange that the value of the lens is less than 700USD, so I'm wondering who would have Canon service to repair their lens.
@@CamerasLensesEtc my guess is they wanted me to buy a new one instead of fixing this one… but thanks to your video its all fixed now and i saved a lot of money 🤘
@@Simoncelica05 Parts and labor don't cost that much.
@@samipso i brought my lens to a canon authorized dealer they sent it to canon canada and they wanted 700$ to fix that lens.. 🤷♂️ im not making this up..
@@Simoncelica05 Wow that's crazy.
Amazing video's! totally underrated channel :) I've subscribed. Thanks for producing your content
Thank you!
¡Gracias!
Thank you very much for your donation!
excelente! lo desarme y arme y funciono a la perfeccion!
These videos are awesome. Do you have one where you just replace the USM or does that require the same full tear down?
I remove the USM motor at the beginning of the disassembly video, so it is very easy to replace it with an another one.
I broke the plastic tab on assembly at 26.00 and superglue didn’t hold up so be cautious when mounting that barrel.
Thank you for the tip!
@J RM I will give the epoxy resin a try. If that doesn't hold I may try heat welding it together. Thank you for the tip.
Great series, much appreciated! However, I'm still having the same issue "Err 01" after replacement, but it's slightly improved since I can take some pictures. Could there be something else that's malfunctioning? The pictures are also not as sharp as I thought they would be, I guess I missaligned the calibration-screws. Thanks!
Error 01 problem: check if the lens gives you this error if you use it other than f/4 aperture. Also, check if the aperture is working by setting it to small, use the DOF button on your camera and see inside the lens if the aperture is moving. As I remember, the IS unit could cause aperture problems: if the IS cable is broken, then the aperture doesn't work correctly, it goes to random positions if you set it to small.. you can check that also with the DOF button. If the aperture is the problem, you can disassemble the lens, check the connection of the aperture flex cable with a multimeter, change the aperture cable, or change the whole aperture unit which is not too expensive on aliexpress. Also, check if the aperture cable is not damaged when you put back that metal holder which bends the aperture cable back... if you push the metal which bends the cable too much, it could damage the cable.
Sharpness problem: There is a lens on the aperture unit which has 3 screws and 3 pins for calibration. When you put back the three screws don't tighten them. First, tighten them lightly until you feel some resistance, then twist the screws back by quarter to half round.
@@CamerasLensesEtc thank you so much for the detailed answer! I will try this after work today and we'll see how it works
@@CamerasLensesEtc hi again, here with the results. 1. I tested all aperture settings and the camera works perfectly on f/4, but gives err 01 on every other setting. 2. Turning IS on/off does nothing, but I guess I could measure the IS cable with a multimeter during my next teardown. 3. Didn't even know what that button (DOF) did. The aperture jumps to random positions like you describe, and it's not always moving to another position. Tested another lens and the blades jump instantly, so there's a problem for sure. 4. I ordered a complete aperture unit that I will try. 5. I tighted those 3 screws very lightly, but I did not back off. I'll try that aswell. Thank you for the help, I've got something to work with now!
Wonderful guide! I came to check how the zoom cam barrel works. The two tubes rotate independently which is quite nice design. Did you just mark the IS colar position so you do not need to re-calibrate this lens?
Which part do you mean exactly? Can you give me a timestamp?
@@CamerasLensesEtc From 19:36. You put back decentering collars and turn them to a position marked on the black cam barrel
@@Guoenyi Yes, I marked the eccentric plastic collars when I disassembled the lens, and I set them to the same position when I assemble the lens.
@@CamerasLensesEtc Did you have to count how many revolutions?
@@Guoenyi No. I have to turn the collar to its original position. Before I removed them, I placed a mark on the collar, and next on it on the lens. You can see the white marks on the lens barrel. Also, the collars have to put back on its original place, so place them next to eachother as you removed them.
Please share the video of 24-105 STM strip replacement.
Do you want anything else?
@@CamerasLensesEtc No, nothing else just what I requested above. I want the video of the back end of the lens where there's a variable lens slide.
Tank you sow much
Excellent video my friend. I have the 24-105 L which the barrel is lose on, any advise on fixing this issue please?
If the problem is that the front lens tube is loose, wobbling or have zoom creep, than you have to tighten the three screws which you see at 26:30 in this video.
CamerasLensesEtc thank you, I’ll make sure I limit my caffeine intake so hands are steady and will dive in. Thank you again 😎
Hello greetings, I want to thank you for the valuable information that you give through your videos, could you help me with a problem I have a canon 24-105 f2.8 lens, it has zoom creep, I already tightened the screws that you will show at minute 26:30 but it's still the same, thank you very much and I hope you can help me
I don't have other solution for the zoom creep.
Hello Sir ! I do every step like you do it and i assemble it seccesfully but when i Start focus thé image is not sharp looks blurry close to sharp
Can you Help me please if you know what i have to do exactly ???
Hello! I had a lens which made blurry photos. In my case the problem was that I tightened the screws in the secondary aperture too much, and that caused the problem. Try to tighten them just a little.
@@CamerasLensesEtc thnk you sir i will try
@@CamerasLensesEtc i did it Again carfully and it always thé same and i think every thing is alright and still blurry no sharpness at all
Is the whole photo blurry, or only the side of it? Can you see the blurriness on the viewfinder, or only if you view it on the computer screen?
Where did u get your flex cable from?
I bought it on ebay: www.ebay.com/sch/i.html?_sop=15&_nkw=canon+24+105+cable&LH_BIN=1
@@CamerasLensesEtc ok yeah I order my from eBay too. Had to wait Foreva tho. Shop from Japan 🇯🇵. I’m just hope I can fix it myself u make it look easy tho. But I’m sure I can do it thanks again!!
You're welcome! Maybe look around on amazon, or filter the results on ebay to the sellers that are sending the item from your country.
@@CamerasLensesEtc well I already got the part. I’m just waiting for my tools to be sent here. But I got the part.
despues de esto, mi lente murio. amen
