I have a Cannon Rebel XS. I kept getting communications errors which I could usually bypass by turning the camera off and back on again. Then one day the lens just froze up. Nothing would work. I cleaned contacts. I switched lens, but nothing was working. I ran across this video and followed step by step and IT WORKS!!! Amazing! Thank you!
What worked for me was to avoid the narrowest zoom setting on my 11-16mm lens (16mm) - it wasn’t this fix, cleaning the lens contacts, or several other fixes on other TH-cam’s - just in case that helps anyone else who hasn’t had success with these tips (which truly HAVE helped a lot of people, so thankyou btw)
My camera is literally my life and when this showed up I was loosing my mind because i was fiddling with the shutter speeds and I thought I totally messed up my camera and you are the only person who was able to give me easy and perfect instructions thank you.
it actually worked. I even went to the service center this morning but unluckily it was closed, so I went hone and searched on google and found your video and it worked. thank you!!!
You're the man , i've just got my L lens back from Canon , they were about to charge me 500£ to fix so i said no and you "fixed" it for free ! Thank you so much!!!!!!!
Thanks so much! My family is on vacation and my dads camera was acting up and he was so upset! It seemed to work in the shade or at night but not in the day or under light! I looked it up and found this video and he doubted it and now its all working! Thankyou sososo much hes all happy now! Thankyou. Worked well!!
Hey!! This is really great. I was thinking to take my camera to customer care for repairs, but I saw your video and to my amaze it worked. Thank you very much for sharing this. I wasn't using this faulty lens since last 6 months and today I needed it and it started working. Thanks a lot.
Thank you Dominic; I had all but given up with my Tamron lens. This is the 2nd one with an Err01 message and after taking the 1st one back I thought I had seen the end of it! But I just got the message again yesterday with a new lens! (Had the 1st not even a month, and this one less than two!!) so far your trick has worked! Fingers crossed it lasts! ;) thank you! x
Thanks for the video. Have had this same issue on-and-off with my 60D and Tamron 17-55 since day one and cleaning the lens hasn't seemed to fix the problem. My only solution was turn the camera on and off or take the battery out. Eventually the camera would right itself... Anyhow just followed your steps - keeping my fingers crossed on future shoots.
Thanks for the help! You saved me $400+ dollars in lens replacement. Wish I was able to see this video in Shanghai, would have been so much more fun taking pics of the city and country side with the DSLR than on my lame S4. Thanks again!!
I'm another happy camper. Tried for weeks to resolve this with my Sigma 18-250mm and T2i. Camera worked fine with other lenses (canon 10-22, Canon 50mm) but had stopped working with the Sigma even after cleaning contacts. Thank you...
Thanks a lot! I got this halfway my vacation, so was frustated quite a bit. I need to put quite some force on my Sigma zoom lens to turn (zoom) it, I though that was the problem. When I push the whole lens back clockwise again after zooming, the error appears less often. But that can't be good for the hardware, so I hope the sequence you described will help next time. Since you were able to reproduce the error, I assume it does resurface every now and then?
Canon 550D with EFS 17-55mm f2.8 "err 01" followed the video showed step,problem remain but after removed battery. the error gone. Someone after tried the steps may need to further try remove battery as well. Thanks for the tips for quick fix.
Will you have to do this every time you want to use that lens, for instance I do that then put on my 18-135 canon and now want to use my sigma again? Thanks
Thanks for the tip! I've had my Tokina llens for almost three years and this Error code just started popping up on my T2i a few weeks ago. Glad there is a solution. Thanks again!
This way unfortunately didn't work with my camera (450d+ tamron 17-55). But I found another working solution: Turn on the camera, then shoot a photo at highest F value, than shoot again a photo but this time at lowest F value. It really worked in my case! I hope it can help somebody ;)
Thanks Dominic. Worked very well after the first test, hope it lasts. My camera is a 550D with a Tamron lens (17-50 F/2.8). Didn't have any problems like this with my other lenses.
Thanks for the info. Everything works for me right up until I lock the lens in place, then the dreaded Err 01 message. I have tried cleaning the contacts and still no luck. The pins are nice and springy, so maybe there is a problem with the cables. I've got another lens contact part on order and will try replacing that.
Worked like a charm! Thank you so much, I've been having this message for a solid year with a certain lens and no amount of cleaning helped but this did!! Thought that lens was in the recycle pile for sure until I saw this!
I have a Canon EOS 50D the communication error code appeared, thankfully whilst at the end of my holiday to Rome, but thanks to watching your demonstration on how to remedy the problem my camera is now fully functioning, many thanks
Dude, this is the weirdest but finest help video I have ever found!. I have a canon 5d and two lenses. It didn´t work with the first one (24mm 1.4) but then i tried with the 70-200mm and fixed it. Tks a lot for sharing your trick!!!!!!
Am using a 60D and it appears to have worked, will be using camera over next few days so will see if the problem occurs again but so far so good, many thanks, much appreciated.
Thanks, My father's Canon 5d Mark II had the same problem. Although the lens is Canon 24-105mm and not Tamron, and the err 01 only appears when it's in between 10% to 90% of the zoom. So you either take a photo with the zoom set to maximum or non to be able to use the camera. But after your solution it's much better, at least it only appears in about 10% of the zoom and only sometimes and not always like before Thanks for sharing this, you've been a great help
Thank you so much! This really saved me a lot of time and money. I thought it was a serious problem that I need to go to the service center to get it fixed.
I just got it working again with a 60d, I had to take a photo with the lens slighty disconnected, then go view the photo, connect the lens completely, and then straight click the shutter button to take a photo. this seemed to work on mine
Amazing! Worked perfectly for me, I had to do 1 extra step which was taking out my battery and put it back on again since my camera displayed the message even when I took the lens off. The rest was a success. Thank you!
Hey Dom, this does not solve my camera err 01, but thank you for posting this video. the lens contacts clearly not the problems as i uses them on a 60D and they work fine, but only when placed on my now troubled 450D err 01 comes up.
I been having the same issue with my 500d. I read I had to take it to bits and replace a cable. Tried your trick 1st thankfully and it worked. Thanks a million
Thanks a million Dominic!!!! On my Canon 60D and Tamron 17-50 it didn't work the first time, but the second time by following exactly what you did, it fixed the issue. Brand new lens at that! I really appreciate you having this tutorial up for this issue! Have a great one Dominic!
This really random sequence of steps worked for me too. I have a T3i and I was only getting the error with a Canon EF 50mm, but not with my EF-S 18-55mm or 55-150mm.
I'm having the same error with my Rebel XSi... unfortunately your trick didn't work for me either. I've tried cleaning the contacts- nothing... I've heard about an internal battery that can be changed (haven't actually looked into that one yet- but read about it)... Someone was saying replacing that worked for the same error. Another issue I've heard is people take off one lens with stabilization on... then put on another lens that has it set to on and it screws something up. Anyway- still working on figuring out a solution... it's the 18-55 lens- my other one works fine.
Worked for a few shots, then Tamron continued to fail. On my lens, worked only at 5.6 aperture! (T1i, Tamron 70-300mm). Shot all day at 5.6 - and fail at all other apertures! The problems seems to be associated to the lens, when they fail, it sounds like the aperture blades are sticking after the shot - not a clean "click". Sometimes it fails on aperture blades before the shot, sometimes after the shot - turning off the camera and back on will give me another chance at another shot/try. Not sure if it is a coincidence, but after trying out the lens in Macro mode, it has worked for the last 10 shots.....
This worked until I locked the lense back. Once I locked the lense back, the message returned. I have canon rebel t4i and wondering if there is any other steps or solution?
That's because with the lens not fully locked, the camera will behave as if there is no lens attached at all (or a non-compliant lens) so it will make no attempt to communicate with the lens. The error 01 only occurs if a lens is fully locked but malfunctioning.
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.
I have 2 Canon DSLRs - I get the error message with T3i. This did not work. Put the ultrasonic lens on my old Rebel. Did this and no error message. However it won't work with the T3i. Also, the viewfinder is very dark with both, in fact I can barely see through it that it is so dark. Originally I found the problem combined with a flashing red light. I had switched my T3i at that time from video to Av. The look through the viewfinder was several circles in the view?? Did not get the error message until several pics had been taken.
Thanks!! I had that problem on a weddingshoot with my Canon 5D MkIII with the Tamron 15-30 f 2.8 vc . For now it seems solved with this tutorial on how to fix the issue :-) . I never had this problem before with any lens and i rented a lot of them. With this Tamron, also a rental, i have the idea not to switch to other brands with lenses than Canon... .
I bought a Canon T3i body and intended to use my lenses my old film Rebel camera but, as per your demonstration, continue to get the error message as per above. I tried your technique but it didn't fix my camera (by not fully engaging the lens to the camera and taking some shots). Could it be that the lenses though Canon Rebel lenses.... that they are not made for a digital camera although they fit just fine and sometimes I even get a great shot. What a waste of money. What to do? Sell the body and possibly hand the problem over to the next person? Have purchased Canon 70D with own lenses now. Groan. marcie
Im using a Tamron 17-50mm f/2.8 (on a t3i) and Im getting this error, really annoying. I did what you explained and it seems to work. But only lasted a couple of pictures. After 2 or 3 pictures I get it again and have to do all the repair ritual all over again :(.
This didn't work on my 100D and rechipped 500mm sigma that worked on a T3i. BUT, when I set the camera to manual mode and entered the aperture as low as it could go (5.6 despite that the lens was a 7.2) suddenly all functions were restored and no error 01 anymore! The camera reads the 7.2 as a 5.6 anyway to allow autofocusing. Seems I lost aperture control but all else seems to be working.

Many thanks. You save my day. I dropped my tamron 17-50 2.8 and begin´s the error 01 on my 7D. With your tutorial my problem is solved.
After months and months of infuriating problems with this, I have just followed your guide and it has worked! Cannot believe it. Thank you so much :)
It worked for me! You are a lifesaver!! I'm currently in a trip accross france and scotland, it was the worst time for this error!!! Thank you!!!
You're the man , i've just got my L lens back from Canon , they were about to charge me 500£ to fix so i said no and you "fixed" it for free ! Thank you so much!!!!!!!
Thanks so much! My family is on vacation and my dads camera was acting up and he was so upset! It seemed to work in the shade or at night but not in the day or under light! I looked it up and found this video and he doubted it and now its all working! Thankyou sososo much hes all happy now! Thankyou. Worked well!!
Thank you so much! I have the 10-24 as well, I wonder if its specifically a problem with that lens or not. My other tamron never had this problem
2 + years later and it still helped so much. Thanks!

Just tried this with Canon EOS 40D, EFS 17-85mm lens and it worked!
Thank you very much.
Thanks so much. Just bought a lens knowing it had the issue but with your trick it works perfectly.Lifesaver. Top man.
This video is much appreciated. Thankfully my frustration lasted about the amount of time it took to search, worked right away.
awesome....my camera was not working with the kit 18-55 and this is the only wide angel I have. Your tips really worked....Kudos!
Thanks for the video. Have had this same issue on-and-off with my 60D and Tamron 17-55 since day one and cleaning the lens hasn't seemed to fix the problem. My only solution was turn the camera on and off or take the battery out. Eventually the camera would right itself... Anyhow just followed your steps - keeping my fingers crossed on future shoots.
That`s a wonderful idea Dominic. I`m sure that it will be a great help to people who have the same problem .

Brilliant. It didn't work at first but I tried the process with a few variations and it worked. Many thanks.
Got this error message for the first time ever this morning and gave this a go. Seems to be all okay again. Cheers!!

A big thanks, Dominic- it worked on my 7D which quite on the middle of a wonderful weekend at Trident, here in Jamaica. Thanks for posting.
So glad it helped you.
WOW! you mean we don't need a new camera! Thanks this just saved us! You are a God among men.
I have a Rebel T5i, tried Dominic's suggestion, and it worked perfectly. Thanks Dominic.
I have a Canon EOS 50D the communication error code appeared, thankfully whilst at the end of my holiday to Rome, but thanks to watching your demonstration on how to remedy the problem my camera is now fully functioning, many thanks

Glad it worked.
thanks so much mate. no idea how you found this out. but the error message appeared after my camera fell into a river ! it s now working !!
Ludo Chem I just kept trying different things out and chanced on it by accident.
Am using a 60D and it appears to have worked, will be using camera over next few days so will see if the problem occurs again but so far so good, many thanks, much appreciated.

+Brian Page Thank you Brian. It's good to hear that the tutorial worked.
Wow! You're my hero! I nearly bought a new lens! Thanks a million!
Dominic, the procedure makes me chuckle (what were you on to figure that combo out?!) but the important bit...it has worked so far, so thank you sir!
It was a mixture of desperation and impatience.
This really random sequence of steps worked for me too. I have a T3i and I was only getting the error with a Canon EF 50mm, but not with my EF-S 18-55mm or 55-150mm.

Thank you so much! I was so worried I'd have to replace my lens. This fixed it!
Hey man, thank you so much. I was worried about my camera but your method worked perfectly. Thanks!!!
So far this has worked for me. I have a T1i. Thank you for sharing!
it worked for me. hope it stays working. thanks for the upload man.
hi dominic i have a canon d60 which does not work with a 16/35 lense but works with 28mm thanks for your input. regards terry
thanks man you
my canon len didnt work but after i saw your video the lens works
thank you
I was freaking out but this fixed the problem, THANK YOU SO MUCH, u rock!
Tried this on a 600D and it worked as well, many thanks!
Worked for a few shots, then Tamron continued to fail. On my lens, worked only at 5.6 aperture! (T1i, Tamron 70-300mm). Shot all day at 5.6 - and fail at all other apertures!

@@bwzffgh7 so the lens can't work again like before
Oh my this was magic thank you so much! literally just got the cam back from the repairs and thought I was going to have to send it right back!
Had to try it twice but it worked perfectly the second time. Thank You!!
Thank you so much. It really works on my 60D. This video should be widely distributed.
This worked until I locked the lense back. Once I locked the lense back, the message returned. Any additional tips?
just the same with my lense. Did you come across any solution?
Thank you so much! So glad I found your video! Was worried this would be an expensive fix.
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.

Legend.
I was second away from ditching my lens-
Cheers!
It worked with my Tamron 75-300 (very old version) and 1100D until now. I'll get you updated with any issue.
same problem here
And it WORKS!!!! You really helped me out man!! Greetings from germany
Wow!. Thank you Dominic. You got my Canon EOS 7D working again.
Worked perfectly for my T6i with the Tamron 17-50 VC! Tank you for saving my life!
Did not work with my Canon 17-85 lens. Can only take a photo when lens is not fully engaged with camera. Glad it worked for most of your viewers.
It worked on my 40D. Thanks man! Your awesome!.
Thanks! i think you just saved my trip on Alaska!
YOU ARE SIMPLY A GOD!!!! Worked greatly. Thanks a lot man...
Thanks!! I had that problem on a weddingshoot with my Canon 5D MkIII with the Tamron 15-30 f 2.8 vc .
For now it seems solved with this tutorial on how to fix the issue :-) .
I never had this problem before with any lens and i rented a lot of them.
With this Tamron, also a rental, i have the idea not to switch to other brands with lenses than Canon... .
Had the same problem with my 35mm Canon lens, problem seems to be solved, thank you!!!
I can't thank you enough! Seriously, THANK YOU.
you are my saviour.. now i can back to work..
Thank you so much! I thought I was going to have to get my camera fixed! Saved me so much $$! You are my hero for the day! Gold Stars for you Dominic!
This worked absolutely perfect on my 7D!
Great! That worked! But now it won't focus manual or auto :( grrr. Suggestions? Thanks in advance!!
Just, make sure that the lens is fully engaged with the body and there aren't any bits of plastic or cotton wool preventing this from happening.
Thanks. It is (clicks). 80D camera body won't change from manual focus in [Q] and won't focus at all.
Am so grateful for this video.... Thanks a lot, it worked like magic.....

Thanks, Dominc. That is BRILLIANT. It works!!!!!!!!
You just saved my photoshoot my man!
It's really works :) Thanks to your video. It works in my 18-55 lens. But unfortunately it doesn't work in AF-mode you should do MF-mode.
Genius! Hope the error stays away. I took a few photos and all good.
Many thanks dominic....solved my months problem...
Im using a Tamron 17-50mm f/2.8 (on a t3i) and Im getting this error, really annoying.
I did what you explained and it seems to work. But only lasted a couple of pictures. After 2 or 3 pictures I get it again and have to do all the repair ritual all over again :(.
This error occurs with my 50mm f/1.8 very often, especially while taking photos in quick succession. should your method fix this permanently?
This worked. Thanks from a very grateful man!!!
Canon 7D - EFS 17-55mm
Hi, I tried dat demonstration on my Mark III, it works only if I don't lock my lens (TAMRON 10-24 also)
This didn't work on my 100D and rechipped 500mm sigma that worked on a T3i. BUT, when I set the camera to manual mode and entered the aperture as low as it could go (5.6 despite that the lens was a 7.2) suddenly all functions were restored and no error 01 anymore! The camera reads the 7.2 as a 5.6 anyway to allow autofocusing. Seems I lost aperture control but all else seems to be working.
Thanks so much! right as i was animating a shot, it kept on saying there was an error. I probably wouldn't have been able to fix it. Thanks again!
