- Canon EF lens ERR01 with error message of lens contact problem.
This usually have to do with aperture module control error. Aperture cannot shut to smaller value either because of the ribbon snap or the aperture control motor faulty. The best bet is to change the whole module.
Here is the step by step guide to change it.

I can't believe I've paid like US$120 for this fix. Thank you kind sir. May god bless your eyes
how were you able to pay 120 for this fix did you go to a local repair shop?
Thanks to you, I changed the flex cable without any problems.
Thank you, This is exactly what I needed.
Great Video! Thank you for shooting this repair. My heart sank when I saw it all apart but since Canon no longer repairs 24/70 1:2.8 L USM I will have to be brave and just do it myself. Wish me luck!
Do you know if they do it for the mark ii version?
Hi. Just wondering how your repair project worked out?
@@WayWalker3 Taking this lens apart was not an easy task, and I would not recommend undertaking this repair to anyone with a faint heart. I had to watch another video to help me with the missing steps. The only other video I found was in Russian, and I had no idea what he was saying. When I got to the aperture module, somehow it opened up, and all of the aperture flaps fell out. I had to reassemble them on my own. That part was terrifying. I took the lens apart several times because things would not align properly. At some point, the lens-sensor focus flex cable snapped. I replaced that one too. However, after so many hours of going back and forth, the ERR01 did not go away. With a heavy heart, I had to let it go. I sold the lens to some happy camper on eBay and I am still mourning its loss.
@@eduardoprudencio5427 I believe so, you may want to call them to find out.
This video has brought smiles to my face, I now know its possible to fix.
I'm having the same problem, only the f2.8 works. Where are you? Can I ship to mine to you so that it can be fixed for me? My location is Ghana.
Very helpful video tutorial. Thank you so much man!
Obrigada pelo vídeo! Me mostrou que eu realmente não saberia arrumar a minha lente 😂😂😂
Com certeza os R$1.000,00 que estão me cobrando para o reparo valerão a pena
(Você fez um ótimo trabalho)
Man, you're braver than Superman - taking the lens apart like that!!
Its pay for my lunch
Nice video!!! next time do a video about focus adjustment lens 24/70 model 01. Congrats from Brazil
Thank you for the video. I have the exact same problem.
Nowhere on the internet i've found a teardown of the nikon 20-35 2.8. I leave as a suggestion for you to do a video on that lens. I have one and I've torn it apart to try to fix it and now stupid me can't put it back together heheh It's kind of similar to the 80-200 you did. Anyways, just a suggestion. Great channel. Cheers!
Best video!
It works!
Thanks for this video
What is the cost to replace this for 24-70 2.8 ver1
Good work 👍👍

Thanks, great demo eh. The bubble wrap desktop nice lens protection. Are popping the bubbles helpful as well during reassembly, for stress relief ? 😷
Nic channel
Great videos for the most common problem in this lens. I wish you wear pair of gloves and avoid any oil residue in the glass surface.
More oil problem if u use glove
@@FotoSunMY new polyurethane gloves is a standard for any repair with optics. It has no residue like latex
Great video. Thanks for sharing. How much does fotosun charge to do the repair?
I can still use the lens at 24\35 mm at f2.8 or i will broke something else?
Hi there, Can I get any aperture module or shall I get a particular one for this lens? What key words should I search for on Ebay?
Hi, thanks for the video! where can I get the replacement module?

Does the lens need to be recalibrated after this?
My canon 24-70 f4 was mounted on my 5D mark 3. I committed a grave error by placing it in a paper gift bag because I did not want to take my camera bag. It was just to disguise it. The bag gave way at the bottom and the camera and lens fell to the tiled floor. I’m 5’11” and it fell as I lifted the bag off a table while standing. It crashed to the floor. Immediately I noticed that the lens had a fault. It wasn’t focusing and there was an incessant motoring sound. The panel on the top keeps blinking as well. Eventually, I started getting an Err01 message. The live view doesn’t work anymore when this lens is connected. Other lenses work fine in the camera. I tried attaching the lens to another canon camera and the problem persists.
What do you think has happened? Do I need to send it in for repairs?
Of coz u need to send it for repair
Mine err 01 happen at any zoom range and any aputure other than 2.8 I used it about four years and repair three time. This is the four time happening again, disappointed going service every now and then. It is a great lens but for so many years Canon build many lens have this problem. Need help and advice. Thank you
Then u should get this part and DIY. Save u time and money. After repair try not to zoom in n out too fast
Kitna cost lagega bnwane me
Same problem on EF 50mm f1.4 after focus fixed
How similar is the L1 to take apart? My iris is permanently stuck closed (even off camera), and whatever came loose is now blocking the zoom mechanism. Zoom bumps into something at 28mm, should go to 24mm. Feels spongy, like the return spring popped out the iris mechanism...
Step are totally different. But the basics are the same principle.
Sir my 55 250 STM sunlight err 01 & normal light condition good work what is this problem please sir reply me
Hol rendelted meg az alkatrészt?
do i need to calibrate optical the lens after this repair ? ...i have this lens with this problem and i am thinking to do by my self this repair after i watch this video....
Usually no need
Hello, I have the same lens, but I have a different problem, which is that the zoom starts at 28 and not 24. What is this problem and how is the solution? Thank you.
Nunca podría volver a armarlo correctamente 😢
Evn I'm facing same problem
Where can I get the aperture module alone in INDIA ?
Where can I buy the module to fix it?
Do you have a website? I’m afraid to repair my lens my self and I would love for you to do it.
We from Malaysia. Dont think is possible to send to us as the postage fees is high
Hi sir canon 55 -250 ka yahi problem hai kitna paisa lage ga
Thank you very much for the helpful video. I have the same problem on my Canon EF 24-70mm f2.8 MKI, but maybe some of my observations might be helpful for this model too for people who can't fix it immediately.
In f2.8 the lens should always work with AF, I saw many other discussions which stated that also.
I also can trick the camera into using different apertures by selecting a high aperture in the camera, e.g f8 and pressing the aperture test button multiple times until the aperture closes. Possibly also by pressing the shutter and getting the error message, but this is slower. It is not reliable, you can't be sure which aperture gets selected, as the aperture closes or opens a random amount. Look at the front of the lens for the aperture closing. In theory f.4 should be the aperture half closed, f.5.6 3/4 closed etc. I am not sure in what increments the aperture jumps, might only be full F-stops or finer or totally random and even enable normally not possible aperture values. Only thing I can tell is that it is much harder to get it to jump to high values, F8 or f11 might be the maximum I saw and these are already rare.
When you think the diaphragm is good, put the setting in the camera back to f2.8. The aperture will stay stuck at what you set it to. The camera will say you shoot in f2.8, but in reality it is a different aperture value. This value will stay until you select a different value from f2.8 in the camera and you push the aperture button again. However even if you find your favorite aperture that way, AF will not work. It will always go from closest to infinite, never finding focus. So if you use AF, set the focus before changing the aperture. To get AF working again you need to select a different aperture than f2.8 in the camera and press the aperture test bottom on the side of the camera until the aperture is fully open (f2.8). Then AF will work again. AF will not work if the aperture is in any other position than fully open.
So it is a choice between only f2.8+AF or inaccurately something between f2.8-f22 without AF and no easy way to know the real aperture without calculating it with test photos. Still helpful if you for example always shoot at infinity and want an aperture over f2.8. Just take a few test shots to determine if you get the depth of field you want. Or maybe you are lucky and your AF is not affected at the same time.
where are you located ?
what if i have this error even when i change to different lens?
easy
all good until re-installing 3 pins on aperture ring to support top lens assembly, the assembly drops too low inside the barrel. As I can't see the iterface between aperture and inner barrel in your video, that may be the problem. Direction?
Lay flat the barrel to assemble instead of top down
your video shows you loading from top and it sits at correct height, I assume its sitting on top of the pins-yes? ruclips.net/video/v_9umlhqRao/видео.html. On mine the gap between the three pins and bottom of top lens module when it's mounted allows pins to unseat and rattle around freely inside the barrel and potentially damage the glass attached to the aperture ring. Plus, I never saw these recessed grommets in my disassemble (part of the problem?) ruclips.net/video/v_9umlhqRao/видео.html@@FotoSunMY
😱😵
Sir only aprature flax cable change
Can i send mine to you to fix?
Can... But i think its too far away.
Please me
