Error 01 is not caused by dirt on the contacts. The error is caused due a problem with the lens diaphragm (usually only occurs on zoom lenses) NEVER use cleaning fluid on the communication contacts on the camera body! NEVER !!
@Montañero Paisa diaphragm flexor breaks due movement of zoom.
Any liquid may cause internal short circuit.
Please tell me what to do ...I'm using a zoom lens how do I correct it
How do you fix it?
@@anyangobrandyshow2934idk if u still having trouble but you go to your camera settings look for custom functions -> Release shutter w/o lens -> and turn it on

Had this very issue last weekend. My (brand new) Canon EOS 80d stopped communicating with my (brand new) Sigma 18-300 zoom. More likely to be the pins aren't making full contact because the Sigma zoom ring is very stiff; it's a known thing with this lens apparently. So probably when I'm zooming back and forth, it's maybe pulling the pins and contacts very slightly out of alignment. Less likely to be dirt or foreign debris as the lens and camera were mated in the shop when I bought them.
A good tip. Thanks. Will give it a try should it happen again.
Did nothing-might try some sort of electrical cleaner but doubt very much this will have any effect
AMAZING VIDEO OF INFORMATION!! I DESPERATELY NEED!!
didn't work on mine camera
it works!
I also suggest go into your cameras setting and do a sensor clean . When I made sure the battery was charge , followed suggestion I looked in the menu and did a sensor clean since I noticed it was doing it automatically. This -worked !
Also when you put the lens on turn the aperture to the highest aperture so f22/29 and take a shot and then turn in it down to as low as it can f3.5 or 2.8 and shoot again I've no idea why this works but it does I
Need to try this , thanks
Worked. Thanks mate
It helped for when it's at the highest aperture (2.8), but if I try going to a lower one it still gives the error. Any advice?
Bruuu it worked in my case jus today 19-06-2024
Worked for me too in my 24-70! Thanks!
I get this error on occasion, but when I do get the error it is almost always at the most inopportune times. I can usually resolve the issue by wiping down the contacts with a lens cloth but your statement of this happening because of the oils on my skin blocking the contacts has me curious, how exactly does oil from my hands cause this to happen when I have never actually touched that part of the camera with my hands or fingers? I have always been super careful to not only make sure that contacts are never touched I also take extra precaution while changing lenses to make sure nothing falls into the body of the camera.
just saved my day - started having this issue just before a wedding and no time to get to a shop to repair or replace it , thanks a million
I'm getting the communication error with only 1 camera body and only 1 lens (5Dm4 & Sigma 28mm) -- the lens works fine on a different camera & other lenses work fine on the 5D --- any ideas?
I had this issue earlier on the 24-105 lens and had to take it to Canon for servicing and it cost me $150. I got this same error today at a professional shoot on the 24-70 f2.8 II, and was shocked that this error turned up in the middle of a shoot without reason. I was worried about another trip to Canon. But on watching this video I decided to try cleaning it with a cloth, and voila, it worked. At least for now. Have another shoot tomorrow, lets see.
Update: Cleaning the lens contacts didn't help. The error kept repeating itself. I finally had to take it to the Canon service centre and it cost a bomb to get the rear end of the lens replaced.
@@hibhaven😅
I just got my R3 back from Canon. I put my 24-105 on to see if it was working ok. Took several pictures, no problem. Then later took some more and I kept getting this error. When I took the lens off it made a noise that I’ve never heard before, like a mirror on a mirror less camera. I tried taking the lens off, that didn’t help., I tried taking the adaptor off (I was using an ER on an R3), that didn’t make a difference, also the battery. Sometimes I could get a few shots taken before getting the error again. I’ve never had trouble with this lens before. Is it just coincidence that it did this after having my camera worked on? Canon also working on the adaptor. I have only had the camera for about 2 months before I sent it in because of focus problems.
@@hibhaven how much was a bomb lol I’m in the same boat for my 24-70
Thank you! I was scared to death that my camera is done for. This video is really helpful, I love that you explained this issue in such a simple manner.
It was weird. It did not work for me either. But what I did was have the camera on on auto with the lens on and the lens on manual and started playing with the ring by zooming in and overturning the ring 25 percent and then taking a picture. Zooming out all the way and zooming in completely and turning the ring 50 percent and took another picture. I did the same steps until I got to 150 percent and the camera lens started working. Hope this helps.
And it worked normally after ? I am getting this ER 01 error when using my 24 - 70 with flash at wide angle 24 mm to 28 mm maybe, I believe its due to some damage occurred to my lens after a fall, will try your solution hope it works.
Mine only happens when my 70-300mm lens goes to about 200to300mm and then I get the error.
GR1M RACER same as mine
Same! This happened on my old Sigma 100-300 mm lens. I wonder why?
Me too. Did you find a way to fix it???
It means the contact ribbon inside your lens is split. You will need a repair.
exactly, this happens only with my 70-300 Tamron lens.
When I'm shooting with 50mm 1,8 on my 77d at specific f2,2 shows this error to can anyone help?
Do you know what that error is called? scheduled obsolescence. That error has no solution and has nothing to do with the lens or contact cleaning. I have several lenses that work fine with other cameras but they don't work with my canon 5D Mark III with Err 01. Service is more expensive than a new camera.
this video is misleading. I think more likely than not, error 01 has nothing to do with dirty contact, because those pin head at camera contact is retractable pins, they are made that way so that when you mount the lens it will press sharply against the contact at the lens side. if there is "oil" on the lens contact that is thick enough that it can prevent the hard pressed pin to not touching the contact, you will have to be really oily, think petroleum tart like oily. It's like if you connect a lamp to the wall socket and it does not lit up, would you think the reason is because your hand oil prevent a good contact? more often I think the problem has to do with defect electronics and circuit board that is connected to the contact, touching the contact with your finger could be the reason but not because of the oil but because of the static charge that burnt the circuit board that connected to it. you would kill your lens much much more likely with static charge than wipe-able oil.
Seriously! What is this world coming to? I don't know if I am more shocked that you made this video or that so many people are drooling over it.... Folks, it literally, yes LITERALLY, says this on the back of the camera. Seems like this would have been the very first thing you do when it tells you to clean your contacts... clean your contacts! What I want to know is what do you do when that is obviously not the problem.
Excellent video. Two comments. First, 'cloth' should mean 'freshly washed, non-'fabric softener'' but otherwise well used 100% COTTON t-shirt. Paper towels are made from wood, which is poison to gold contacts. Fabric softener leaves residue. Non freshly washed will have body oils which are leave residue. Synthetic cloth is plastic and can be abrasive. Second, solvent really shouldn't be necessary, but if you have to the only One True Solvent is grain alcohol. All others leave residue. I know this sounds super extreme but these contacts are super sensitive. Pencil eraser, might as well use 220 grit sandpaper, followed by throwing the lens in the garbage. The WD-40 mentioned made my neurons absolutely cringe OMFG!! BTW the worst effect of residue is not just that it is an insulator, but that it collects dust/pollen/micro size smoke particles from the air.
Thanks for the useful information!
Good job sir.
thanks for the comment! I have a little question, would microfiber cloth be alright as an alternative? I have quite a number at home with my spectacle cases so I was wondering if they work fine as well.
I had this error as I use old lenses and adaptors so the only solution for me is to put gaffer tape on the metal where the adaptor and pins meet works for me..FYI. this is for use with a canon ds5.. I do have EF mount lenses but they keep saying the error so put gaffer tape on the pins of the lens *Not the Cameras pins* This means you can only use the camera in manual mode which is the mode I use all the time..
My camera gives me this error at a dim lighting setting anyone knows how to fix?
Skillzy I have the same exact issue. But seems like no one never mention it 🤷🏾♂️
MEE TOO! how to fix it please!
Does NOT work. It is the "band" - inside the lens - which is broken and needs to be replaced.
Everything else is rubbish
Even though i tried already, after watching the video and trying again the problem was solved!
I bought Canon 28-300 3.5 - 5.6 lens and working only on lowest aparature settings. So 28mm f3 5 any higher error 1 no matter what you do also on 35mm, 50mm etc
I keep getting this with 2 of my lenses, but only at 1 focal length, change the focal length even by the smallest of 3mm and it works
I have a Tamron 18-200mm, canon mount with this issue.
General camera repair in Pasadena couldn't fix it. Any suggestions?
bro i have same probleem
Same problem here
just bought the tamron 16-300 lens, only have this problem when shooting long exposure. when using stock lens its fine!!!
Greetings!
I have a Canon R3, so far it has happened that the display says busy.
I can't turn off the device, I simply had to remove the battery and everything worked fine, and then after 2 months the same thing and a few days ago the same symptoms for the third time
Didn't work
You saved a weekend getaway with this fix! Thank you so much!
Hello,sir!
Err iso 200 canon 750 d
How could I do,sir?
I hope you give me the answer.
Thanks 🙏❤
Contact cleaner would work, NOT WD40!!! NEVER BUT WD40 IN ELECTRICAL DEVICES!!!
Pro tip - it's not *always* simply that the contacts are being dirty. My 24-70/F4L USM does need a new fladbed cable, and i do know other Canon lenses with that issue as well, like the old 17-40 L. You could believe that i tried *everything* all the web tips, but it's bogus. I need to replace that special cable inside my 24-70 F4L. Sometimes, ppl get a tip on the web, and think it'll fix everything, but it doesn't. I shoot >34 years, FYI. Get my lens repaired soon. 🙂
My Canon 6d is having trouble with my Canon 100mm macro but it works with other lenses. I put the lens on my Canon 1100D and no problem.
I do have the same issue but there is also a electronic noise coming out of it (not always but I'll say 90% of the time). Noise that I could not explain unfortunately, but I'm a desperate... T.T I want my 24-105mm back ... Please guys, help me !
I still get the error idk what the problem could be
I have 5d mark 3. I can't click photos bt either m useing live view mode thn click photos... any suggestions please
Error 01 the problem is stuck diaphragm. Suggestion way out of the ball park
Thank you Very Much, you really saved Me with this fix! And it Really Works
Err 01
Communications between the camera and lens is faulty. Clean the lens contacts.
figured it out: only get the error when using the zoom lens...and the battery is running low...
Luckily it’s the 50mm lens that my camera came with, I usually use a 300mm and it works.
Thank you! I should have search for this video, years ago.
You just need you Lens Aperture Group Flex Cable replaced
i tried it but again same issue after i take 20 to 30 photos plz reply me thanks
Life is fun same
I walked away from my camera and it dropped on the carpet so now it’s saying a error. So I think I have to take it to a camera shop now or leave it alone for it don’t say it anymore
i tried that and did not work. even tried alcohol and qtip.. still not fixed. it got wet so it could be damaged more.
Thank you - that made so much sense and was explained so well
I have a problem with my 650d cannon wen I press to take a photo it's not allowing me to take
Does not work for me. I think you should mention that often simply cleaning doors not help.
Gracias por compartir.
Pero este problema no me ha sido tan fácil de superar.
En mi caso, son basta con limpiar los contactos.
Saludos desde El Salvador.
dislike for this video i will no even explain why also welcome to black list
This problem only occurs with my 21-year-old Sigma 70-300 1:4-5.6 APO lens on a brand new M50 MkII using the Av mode with the aperture set at any value smaller than f4. Seems to be okay on Tv and P though.
Same with my tamron 70 300mm. Tsk
Hi, I think I put my 24mm stm in my backpack and might've bumped it a little, it's not even getting recognised by the 70D now... Aperture shows 00, no motor sound inside lens, AF-MF doesnt change anything and Err 01 when trying to shoot. Any idea?
Hi, I have the same problem. Do you have solution yet?
What , then you just said ,"clean it , if doesnt work i don't fuckin know what else its goin on"
Right, when it said "clean the contacts" the first time, I naturally cleaned the contacts repeatedly before resorting to RUclips. But by why does this body need to communicate with the lens in order to record an image you just shot? Warning comes right after releasing the shutter- My autofocus and iris are working fine, it will AF and close down and release, but then after freeze on this screen and not write the image file; which is clearly irritating when you thought you just took a photo. More curious because I sometimes use old or dumb-adapted or cinema lenses that have no electronics or AF, and they work fine with the camera, every shot. Like, do you know a menu setting or firmware upgrade or something to tell it to record the shot regardless of whether the body can chat about it with the lens after the fact? Like "ignore post-shot focal length metadata" or something?
Thanks it worked....and I DID use my t-shirt LOL.
Interesting video.... So what if the lens has a very tiny bit of play once the "click" has been established when installing the lens?
The tip really helped me out today. Thank you very much for making this video @LensProToGo😀
Nice, I was cleaning my contacts with alcohol and a q-tip, just used a cloth and a little elbow grease and IT WORKS!!!
Did you actually use elbow grease or just a half second brush over with the cloth
dude. fixed my wifes 24-70 just now. she cried as she was so happy. thanks man
My camera only seems to show this error in AV mode. Why is that happening only in that mode?
I also had this happen in the SCN Sports mode. So it's not just AV
This isnt helping. What is the best cleaner to use on contacts?
.for those using off brand lens..i found the error came up when i used dslr canon with "pull style " manual/AF on the lens,it showed the error when i kept my pre-sets on ( portrait,sport,TV) and used manual setting on THE LENS. i am thankful for your video for helping with cleaning process..also!
sondrag2 m
you saved my life. I've forgotten about the af function for auto and Mf for manual. thanks
So what settings should I keep it on
I have done like this but now auto focus is not working
Thanks for this ..i did it n solve the problem😊
Thanx its work 👍🏻🇮🇳💗💗💗
i tried cleaning still not working
Rajendra Biswas but it's the lenses fault..... Tamron 70-300
akhil krishna I have the same problem with the same lens
I also have same problem with same lens specially when I zoom till 300mm and F> 7
Im having problems with a canon lens and cleaning is not the solution
Many times you only need to twist the lens on the mount a little for the connections to form correctly.
this is what saved me thank, you sir
you absolute life saver i love you for this thank you
j ai un eos m50 , un message s affiche disant " tourne la fleche de l objectif vers le haut pour active le viseur .
It's still not working for me
Hhmmm ... Unfortunately it doesn't work for my Tamron 70 - 300... :/
I have the same objective with a canon eos 80d and the same error (random appearing)
Thank you so much! I appreciate it! ❤️🤞🏻
Your attention to detail in diagnosing and fixing issues with Canon cameras is truly commendable.
I had already wiped the contacts with no luck, but this video made me want to try again. I used a different cloth and spent a little more time wiping it down. Unbelievable, it's working again. I took over 100 photos with no error message. In the past, up to 10 would return the error. Sure hope it lasts until I can finally afford to purchase an R setup.
Thanks 👍🏼👍🏼
bro...still dosen't work!!
Thanks for helping! I was about to go to a camera store to get it checked, but when i followed these steps it really helped! Still sad because i couldve had nice pics but it kept having errors, its okay now, thank you! 😅
Very useful video, thanks!
sometimes error, sometimes working properly. Whats a problem ?
Tommy Pratomo did you solve it? How?
Muito obrigado, solucionou efetivamente meu problema com uma yongnuo 50mm f/1.8 II
IT WORKED FOR ME!! Thank you so much, lifesavers.
뭐라는 거냐.. 기존 방법으로 닦지 말고 as 맡기라는 거냐..?
I tried what you talked about and the lens still does not work. Please reply
Thank,s for nothing…..
Cleaned, doesn't work.
I wiped the contacts with a lens cloth and even turned it off and on. Message returned the moment I tried to take a photo. I got no photos at all today. Got home and took a picture of the tv screen. THAT worked. Weird.
c'mon. Really? That solved it? My mother having same issue and we are trying to avoid the $$$ repair bill
@@unknownKnownunknowns no, eventually I had to replace the whole lens. Darn it.
Camera view is dark
wow that worked thanks so much
Thanks
If you have any lens trouble there's always the Canon Live Chat service, very helpful. imaging.chat
Worse video ever lol 😂
didn’t work
Perfect directions! Thank you! Works like new again!
Thanks
During cleaning the contact, one of camera body contact is pressed inside, (fixed inside) going not come to release(outside) so how to release camera body contact????????
I have the Err 01 error with my 70-200. My resolution was to switch batteries. Go figure
Hey, Even I think my battery is the problem. I put it to full charge this morning and by evening it ran out of charge although it was not used throughout the day. Did you replace the camera battery or the Date time battery?
Did not work
What does Err 11 mean?
If you have a lens error 1 it is an intermittent fault inside them lens if cleaning the contacts do not work other solutions like putting the lens on then backing it off slightly does not constitute an error fix.
The problem lies inside and will need servicing as most quick fixes is not a permanent solution you can also short out other electrical parts of the camera.
With The error I message clean contacts is what it says there are other ways like manual mode select maximum aperture turn camera off then turn on and select minimum aperture turn off this sometimes resets the chip inside the lens also removing the battery and refitting may also fix the problem other wise it's a service job
DO NOT - buy a EF lens used with any electrical problems at all the seller knows it will be a very costly job to fix after all that why he is selling it .Only buy used EF EFS lenses if you can pyshsically try them on your camera.
