This is my first guide and also the first lens I take apart.
My english is crap and the result of the video the same. However, I decided to post it anyway, maybe it can help someone.
As I say in the video, this fix didn't repair my lens because I have another problem. But it should help with several other autofocus issues. My issue is that the lens can focus fine from infinity to near, but not the other way.
Please let us know if this fixed your lens or not!
Sorry for the low volume.

He doesnt remind you to put the first part back on when you start to
reassemble. There is an image though of the small part reattached. This
should be apparent if you do it straight away but if you go away and
have a cuppa and come back you will probably be half way through
reassembly before you realise.
Also when you take the Auto Focus switch off he does warn you to be
careful as its fragile. He does tell you when hes reassembling but
not enough emphasis was put on turning it to AF this time. The switch
is like a hair, if you breath on it the wrong way it will snap.
When there are very few people doing these videos you have to appreciate
someone trying, if you are aware of the switch (its a surprise it does
bust within a couple of days of using the lens to be honest) and dont
make any mistakes its a good guide. You dont have to be pushing hard to
snap this switch, you just need to have it in MF instead of turning it
to AF when reattaching. It seems like a string of people have had this
problem, check below comments.
Im about to buy a wireless follow focus anyway and its mainly video I do
so its not such a problem, but would be a disaster for photograher,
infact AF is always very handy to get that precise focus when setting up
a shot.
Great feedback, thank you! Can I up this comment somehow so it will be a "sticky" in the comment section?
Done, made it a sticky in the comment section now. Thank you!
By first part they mean the part that is removed in 5:37 in case anybody was wondering because I was.
Mine is sometimes not focusing. If lens is pointed up, it won't turn focus past a certain point. Pointed down, works great. I'm pretty sure mine needs grease applied on the white plastic slider guides. Any thoughts on what type of grease to use?
This was just what I needed to fix my lens. The focus was stuck, probably due to a bit of dirt. Now it runs perfect. Thank you very much for your very fine and detailed video!!
I called my local camera repair shop and they wanted to charge $150-200 to repair this common problem. I've never taken anything apart that is this delicate. Your video was perfect! Instead of using my hand to flatten out that cylinder I used a flat capernter's square on the top and the bottom pressed against my flat desk. I used a carpenter's grip (Irwin Quick-grip) to hold that position for several minutes. I kept going at it until it was close to flat as possible. Your steps were exactly as you stated. Thank you again, my 50mm lens is working again. I also managed to clean out the tiny bits of sand I found in the outer slide and gear track from one of our many beach trips. Focus is a little smoother now too. I couldn't find any machine oil so I used Phil's bicycle grease (just a toothpick tip dab) on the sliding parts. Focus is smoother and couldn't be happier! Thank you, thank you Christofer!
Patrick Lacson Very happy to hear that Patrick! Hope the lens stays functional for you and thank you for commenting!
My first video with my working 50mm lens, thanks to you! ruclips.net/video/0Xb68wnu8Ac/видео.html
I can not thank you enough for this video. I just fixed my 50 f1.4 so quickly. The guides were quite bent when I opened it up and it didnt feel like I was able to get them completely straight again. I put it back together expecting it to still be broken and wow, its fixed. Both manual and auto focus fully working. Your video couldn't be better, clear, concise and well structured. Thank you for sharing your skills, very much appreciated. :-)
Thank you so much !!! You helped me a lot . When my Canon broke , I was very upset , but thanks to you I have everything repaired . Thank you very much!!!
Excellent! One of the best clearest and most helpful repair videos for a common problem.
Helped me fixe my Canon 50mm 1.4 close auto-focus problem.
Thank you so much!
I don't have a problem with my lens, I don't even have one... but I have watched you with pleasure, very nice video, straight forward, great narration. Cheers from Canada!
Hey Christof, AWESOME video! I just fixed my 50 f/1.4 in less than an hour. Your video was perfect... precise, well shot, and complete. Thank you! I'll be sharing this :-)
Thank you Matthew, that's some nice words! Glad to be able to help!
i got to fix mines as well, this was a pretty scary operation but mission accomplished thanks to this video!!
what was wrong with it?
Abram Hodgens, yes fixed the bent focus ring! Thank you for this video!!!
Thank you so much for this video. Once I stripped the lens down as per your instructions, I could see the focus barrel was quite badly bent out of shape. I tried to fix it as described but it was too far out of alignment. I ordered a new one for €14 and replaced the old one. The focus scale easily peels off and can be reapplied to the new barrel, new barrels do not come with them. I put it all back together and its working perfectly. Your instructions are super easy to follow and the video is clear and well put together. Thank you again!🙏😀
Just wanted to say thanks! This seemed like a daunting task but with your video I got through it and very happily fixed my focus issues - previously the focus was stuck down the infinity end but I'm back to having full movement through all lengths. Really appreciate the video, thanks so much.
+Marc Roberts just curious, if your lens was stuck on infinity but did your focus ring still move? I'm trying to figure out if this tutorial will help me fix the lens or not. I dropped it.
Thank you Christofer! With your step-by-step video, I fixed my lens!!! I truly appreciate your time and effort in making this video.
Glad to hear!
Your tutorial worked great! It took me about 45 mins. In addition to flattening out the piece you showed, i filed down the part the guides sit in to slide easier.
Pro tip for everyone using this tutorial: make sure the ribbon you removed is inserted all the way and the plastic bit with the tabs on the back of the lens are properly seated or you will have aperture errors! :)
This fixed my issue and was great to have the step by step from disassembly to reassembly. Very well done!!!!
Nice man!
Really great guide. My wifes lens was defective after it fell down. The "most common issue" described here was the reason for not functionng anymore. I bent the aluminium part back in place and now it's almost as new. All in all it only took 30 minutes. Great job Christofer. Many thanks for saving me a few hundred €.
Thank you so much for this video! Your instructions are so clear and easy. My first lens fix was a success! I'm so happy I got it working again!
I was convinced that I was going to totally break my lens and have to buy a new one, but I actually fixed it!
You saved me 2/3 of a new lens in repairs. Highly appreciated
+drunkentre Glad to hear you could fix it!
You just helped me fix my wife’s lens today after our toddler got ahold of it and dropped it! Thanks a bunch!!!
Kanonvideo Christofer, stort tack. Mycket tydligt och pedagogisk. Mitt objektiv led av sned plastring. Funkar perfekt nu.
Thank you SO much for making this detailed video. I dropped my lens while on vacation and Canon suggested I have someone hand carry the lens back to the US and then ship it to New Jersey, which I thought was ridiculous. I am going to be away for months, so I decided to fix it myself and when I got to the end of disassembly, I saw the ring was bent. After pressing it back into shape, the lens now functions! The motor is a bit slower than before but it will keep my photography going while on my trip.
One note: At the 5:40 mark you remove a rectangular metal piece but do not remind viewers to replace it when reassembling. Maybe you can add this as a note in your written description.
Thanks again for the tutorial! X
You're a bloody legend! Thanks so much. The issue mine had was as if the focus ring wasn't gripping, like there was a slipping cog inside. Once I was able to locate the cogs I just jiggled them around a bit, and maybe that fixed it, or just opening it up did something? Those first screws were a nightmare to undo, so my palm is very sore from the screw driver. Thank you again! You've saved me hundreds of dollars!
i just droped my canon with my 50 mm 1.4 lens connected and my heart came out my chest when i herd the loud bang on the floor. nothing seem to be broken until i started using the camera and noticed my lens didn't want to focus. thank you so much for this video i got to fix my lens following everything you did! THANKS!!!!!!
So glad to hear that the video could help you! Thank you for those words! :)
I'm amazed at myself for actually getting this to work in the first attempt. Thanks for the great tutorial!
I couldn't get the ring completely planar with pressing it on a table, so I used a fine wood rasp for additional corrections. If you do this, you probably better make sure to have some compressed gas at hand to remove all the shavings.
Fixed my new (bought used) lens! On my first dslr, my first lens, had it a week before it lost focus (i probably bumped the front or something). But now it works great again! Thanks a ton!
Thank you so much Christofer! Clear and easy to follow guide, even I didn't have any leftover screws :-) Fixed my issue of not being able to focus between 0.45 an 1.8 meter. Made me happy!
I haven't used my autofocus in years, but my manual focus recently stoped working properly. thank you for your detailed video as it helped me get the mf back running! thanks a lot
Totally fixed my lens! Very thorough and accurate video, perfect. Thanks!
Thanks! My issue was the same warping problem you showed. Followed along and fixed mine. Works good as new now. Many thanks for taking the time to put this tutorial together. :)
Great to hear it has helped you!
YOU'RE A GENIUS! Thank you sooooo much for this! Your guide was helpful, clear, concise, and extremely informative! This fixed my lens, and saved me the $200 just to have it repaired at a shop. Thanks again so much!!
Thank you! Don't forget to thank the original inventor of the fix. It's in the description. I just made the video to make the process even easier to follow :)
AWESOME! Fixed my 50, this is the second time this happened, last time it cost me $200. I DID buy the lense-shade today though, it will stay on _permanently_
Thank you man! i fixed my lens... i broke two of the little clips :( they were too fragile but it´s ok ...i can live with it...you made me save 100 bucks!
I manage to fix my lens!!!! Easy to follow tutorial, with all the information needed! Thank you sooo much!!!
Thanks so much. I had been putting off paying to get my lens repaired and I am glad I did. This tutorial helped me fix everything. Thank you!
So glad to hear that!
This fixed it! I never would’ve guess that was the issue. Thank you for sharing this!
Hi Cristofer, fixed mine too, it was very badly bended, even not able to bend it back by hand! Used an oval pincet, to bend the ring back in shape and used some fine sandpaper to make the edges of the groove smooth again. Greased it with some white grease on an ear cleaning stick. Auto focus works fast and acurate again! Thanks!
Thank you for this!
I had an communication error and I knew that my aperture's blades got stuck
I disassemble everything just as you did and even more just to reach my aperture.
I used air pressure to loose my blades and it worked!
Thanks!
thanks, just got my lens fixed today from your instructions. well done. cheers mate.
Just fixed my lens in 2021 thanks to this guide! Thank you very much! 👌🏼👍🏼
Thank you very much. This helped a lot. My lens fell on the floor and neither AF nor MF worked anymore. Straightening the bent channels solved the problem for me.
Many many thanks !!!. I did it following your steps and now I have my 50mm up and running. Each euro counts in this expensive hobby.
Great job, and thanks for sharing it.
Glad to hear that it worked for you! Indeed, it's an expensive hobby!
Thank you! I wasn't able to get the very last screw off to realign the barrel but I managed to straighten it by pushing the metal piece through a crack of wood in a flat surface. Now my autofocus works!
I drop my lens and lost focus from 0,4 to 0,8m. With this video i was able to fix it. Thank you very much ;)
I'm glad you exist in the world. My lens is functioning again. Never take down this post.
Oh my God, thank you so much Christofer! I was already about to give up but now I'm so happy! It worked fine. Thanks for the great instructions!
thank you for a very clear and detailed guide on how to take apart this lens, thanks to your video I was able to repair a friends 50mm lens and save her a lot of money in repairs!.
Glad I could help you!
Thank you so much for taking the time to create this thorough guide! My lens is functional now! 😄
Glad to hear! :D
Excellent video. I had also like many here bought a second hand lens which looked like someone had tried to fix. Was getting stuck at .45. Followed the instructions here, straightened it out and now it works 110% better. Also great tip as I had to deal with stripped screws is duct tape on the screwdriver sticky side on the screw head and go slow. :)
My old lens quit focusing, and even was stuck so manual didn't work. Using this excellent walk through, I was able to get the manual focus working again.
I can hear the motor chirping for a fraction of a second each time I try to focus, so I'm assuming that it's pretty much fried.
I didn't have aperture control at first, but after a comment a few above, I saw that re-seating the ribbon can fix it, and it did! I still don't have auto focus, but at least I'm not stuck at f/1.4
Thanks a lot. Although I don't fix my lenses myself, this vid also helps because I can learn here about where the weakness is and I can better protect my lenses. My 50/1.4 went down a few times I guess the problem is the same piece that is mentioned here deformed and then caused the motor to overwork and breakdown. So my protection method is the put a hood onto my new lens as much as possible to shield that piece from bumps that may cause the deformation. Thanks again.
Thanks! Looking forward to trying to fix my lens (or at least figure what's messed up inside)… it's been wonky for a long time now. Won't focus all the way to its minimum distance, sometimes gets stuck in place and I have to push on the barrel a bit to get it to move again. Appreciate this detail and the steps.
PLEASE READ! 1) FOR BEGINNERS: THANK YOU! This worked for me and I have no experience disassembling anything. 2) I just needed to buy a $10 precision tool kit on amazon 3) I messed up putting the connection back in place and when I reassembled everything and took a photo, the camera said “communication between the camera and lens is faulty.” I had to disassemble again and connect it correctly. Then somehow when I closed the lens back on the camera it wasn’t aligning and the lens release button wasn’t working and the auto focus wasn’t working. I had to twist really hard and the lens came out. I did the entire thing again and by some miracle... it worked. I can’t believe it. Took 1.5 hours but saved $$$. THANK YOU AGAIN!
Thanks! Worked like a charm but I had to dismantle it again since it gave me an Err 01 ... it was because of contact band from the optical assembly, I did't tight it as I should. After I tight it well everything worked perfect.
This is brilliant! I was quoted £95 for a new motor, plus postage. This had it fixed for free within half an hour. Thanks for posting
Thanks very much for this, absolutely spot on instructions and lead me to the exact problem that I was experiencing, the deformation on the inner focus ring.
brilliant, thank you, dropped my lens a day before flying out and saved me a lot of hassle getting it fixed
GREAT video, very thorough. Other videos about this miss a few important details... Thank you!
You fixed my lens my friend! It works perfectly and your instructions were excellent. I can't thank you enough!
SL Opit Glad to hear :)
+Christofer Cederberg just an FYI to people using this method - I had to fix the lens once again and have realised that tightening the white guides for the focus ring too much can also cause the focus to get stuck. So make sure you tighten the screws so they are flush, but not so much that the focus ring feels solid and difficult to move.
+SL Opit Thanks alot for the input! Maybe this can actually be my problem, I will try it again. Thanks!
been wanting to attempt this for ages now, eventually got around to it, sorted my lens out, thanks for the video
I was in the same situation. Follwed the forum-guide linked in my description and thought it was quite easy. Was also missing a video-guide when I did my attempt so therefore I made this to make it easier for others.
It took a long time for me (first time is always a struggle) but fixed beautifully. Incredible tutorial. Thank you!
Glad I could help you!
Thank you so much ! I had some issue the first time, my aperture was locked on 22, the problem was the connector I did not plug right. You just saved me 340 euros
I bought a Canon EF 50mm / 1.4 at a blind auction. It didn't work. But your repair guide fixed it! Thanks.
Nice!
thank you so much! you just saved me. focus ring got disformed and I fixed it with your help.
This is a great tutorial. Fixed my lens to better than ever. Did have to superglue one of the clips back onto that plastic ring, but it went back together well. The only thing you didn't address which took me a couple trial and errors to figure out, was that silver piece and screw (last one removed). Took me assembling then not finding it where it should be then assembling it again. But overall, you solved my issue!
Thank you very much!
Thank you! Good to hear what I´ve missed as these comments will help others looking for the same answer!
Thanks for the video, mate...I had the same issue and now I can play around with my 50mm again...Thanks again!!!
Thank you for the very helpful video! I've never taken apart a lens and managed to get through this with a lens in better condition than when I started - it focuses properly again. One tip, store lens at infinity and get an EF-71 II lens hood to avoid (hopefully) having to do the repair again.
Glad to hear you fixed the lens!
Thank you for this guide! With your help I was able to fix my lens. :)
Appreciate the effort Sir!!! I had to buy a new spare part as well as I messed alot with the barrel and was not able to remove the very hard screw. All is fine now and thanks to your awesome instructions. Cheers!
+Ahmed Selim I couldn't remove the final screw either though still managed to flatten it out with the last metal tag in place hanging off the side of the bench...
THANK YOU christofer! you just saved me 380 dollars! i dropped my lens and I didn't focus anymore. manualy and automatic. this saved everything, and it works better then before! thanks thanks thanks thumb up thanks!
Awesome, hope the lens will continue to serve you well. It's a fantastic lens really!
Good day. I am from Russia. Sorry for the translation. Thank you for the video. It helped me a lot. Everything is very detailed, step by step. You helped me save $ 60-80
Thanks a lot for your brilliant step by step tutorial! Was able to get my 2 yr old lens back to work. Save me a trip(& $$) to canon repair center!
Je viens à l'instant de réparer mon 50mm 1,4 grâce à ta vidéo. Merci beaucoup ! C'est cool d'avoir mis l'étape du remontage.
Pour la pièce déformée, je n'ai pas constaté de bosses ou autre, je l'ai quand même mise à plat sur la table en appuyant avec ma main. Le simple fait de démonter l'objo à peut-être décoincé la chose. Meme en manuel je ne pouvais pas faire de MAP.
Thank you for this video. It fixed my lens where the focus ring was stuck completly!
One tip though, be sure to put those flat cables all the way in before you fasten them with the white clip. In this video it did not seem that you had it all the way in. You should not see much of the bare copper contacts outside the connector.
Good tip!
The replacement tube i got was crap, no sticker on it either to show the measurements. So i left it, for months. Sat with it looking at me the whole time. Decided to give it one more go, took out the crappy tube and threw it far away from me, squished the crap out of the original one they way he does with his palm, put it all back together and hey presto, it fecking works. IT WORKS!!!!!!! Autofocus is really crap for some reason, tried it on two different cameras, but it keeps hunting erratically never stopping but i don't use it for video i use it completely manual. So glad to have this wonderful little (poorly made) lens back in circulation again and i bought a lens hood for it and it will never be off it from here on. Side note, the gears were rather stiff so I thought maybe the lubrication had dried and added a very small amount to the gears (plastic and rubber safe) to assist it, this may be why the AF is freaking out because it's maybe shorting something. Cheers for the vid.
Thanks for the help! I dropped my lens and it stopped focusing. I fixed the ring, but it still was sticking at some points. I ended up leaving one of the 3 white sliders off and it works... we'll see how it stands up
Thank you very much. I have no experience of opening a lens before and I just fixed my lens in under an hour. Thank you again.
Great to hear that the video could help you! Hope it will survive your adventures in the future! :)
I had never thought about retracting the zoom to infinity to store it before. I will now!
thank you for the video. had to go further and get between the lenses to clean because of sea water. but i definitely needed the first steps as shown in your video!
Glad I could help you Alex!
I dropped my lens 6 years ago at Comic Con. Since then its really hard to adjust focus. Thank you for posting this video, I am going to try taking it apart and seeing if I can save it, if not I am probably just going to toss it.
Brilliant video, followed it step by step and the fault is now fixed. Many thanks..Phil
+Phil Durkin Glad to hear that I could help :)
This really works guys I bought a 50mm 1.4 on craigslist and it had this focus issue....I was about to get rid of it till I tried this..and surprisingly it actually works...only thing Is pay close attention to when he says be careful...and apply a lot of pressure from the start so you don't strip screws...I came close a couple times
Glad I could help you! Always sucks when you buy something used and it isn't what the seller said it would be.
You're right about the screws. Be sure to use the right kind of screwdriver with tight fit and be carefull not to strip them.
I also had to redo this procedure twice. I did not correctly inserted the electrical connector and as a consequence I got aperture control problems (it got stuck in my basic tests at F22).
I figured that it might be the connector, reopened the lens re-inserted it (fully in - I could almost swear that it is now even more inside than what is seems to be on the video) and it is now working as expected.
Thanks for you very helpful video:)
Nice, glad you share your experience! Will check that my connector is in all the way next time I have the lens apart. I have not yet examined the lens further as I have another working one.
Thanks for this, my aperture was stuck at f/22 but it was because the connector was loose as well.
thanks your guide is very helpful. Now my lense focus again. I didn't noticed anything was bend, but maybe only a little something is required to produce this focus issue. It is a bit of a shame Canon uses such a fault-prone mechanism.
For people that get the stuck aperture blades after re assembly ( Everything is dark ) - I just had this happen to me, dis assemble the lens and reconnect the long ribbon that you through through the lens seen at 8:33 . Then re assemble and should be all sorted. @christopher Cederberg , thank you for your detailed video, it saved me a lot of money :)
Great tip there!
Thank you, glad to hear you fixed it!
Mad props!! You just saved my lens and some good cash!! Thanks for the tutorial!
Great video! Neither or the video are crap, both were super useful thank you
Thanks Christofer, excellent play by play,worked like a charm,you da man!!!
Thank you Victor! Glad I could help you!
Thanks, i just repaired mine. Unfortunately i have problems with the gears too. There is a strange part with 3 bearing balls. The bearing seem to be damaged. Or maybe i will replace the whole AF assembly as you did. Right now it's working.
Great video, slow and informative for someone who hasn't done this! Unfortunately, this did not fix my lens, I assume its a motor issue after some deeper investigation. Thanks again for the helpful video!
Thank you, maybe it's the same problem as for me. I've not yet replaced the motor as I have another copy of the same lens.
Ohhhhhhh you just saved my Lens Thank You Christofer i had problmes with the last screw it was stiping off
Thanks for this video, it helped me replace the problematic cam barrel that these lenses employ
Thank you Christofer It fixed my focusing problem after i dropped my camera face down. as a tip if the lens wont go straight after pressing check the high point and tap it with the handle of a metal knife whilst holding the blade it had just enough power to knock it back to shape, When ressambling 8.49 on video replace the three white tabs and the turn the white focus dial to see if the cameramoves soothly. if not check the diagonal groove for minor deformitys tht stop the white tabs moving smoothly. Than you agin it saved me a lot of money in replcing it or sending my lens foe repair.
I have just one question. It fix my AF I was able to focus just between 1.0m and 2.6m. Now my AF works perfectly, but when I am using manual focusing ring, it is still sticky and I have to use little bit of force to move, but after that I can´t focus properly, because it´s not smooth. May you help me with this?
Hello Jakub. i have no camera repair expertise but from what i saw when disassembling my lens was that you problem may be caused by damage to the manual focus ring as seen at point 13 seconds in the video when Christofer removes it. Look at the teeth cogs on the inside of the dial/ ring for damage or missing teeth, look at the white dial (revealed at 15seconds)that the ring rotates for damage. See if you can reverse the ring when replacing it you mmight have replced it th wrong way or the other side of ring might not be damaged.. at point 18s you can see the white dial. roll this with your fing and see if the focus changes both ways. f so you know tht the focus ring is the problem. otherwise i dont know..Good luck.!!
Thank you thank you! My lens wasn't functioning properly and after the dissection and reassembling, it works again!
Thank you!
I used your video to disassemble and clean my lens a little speck of dust.
I think I can help you as AF: I noticed that in your video, you put the little switch to the left and the AF button to AF. On my machine did not work the AF, then disassembled again and put it to right, it worked!
Again, thank you.
I'm glad to hear that the video have helped you. My lens can focus, but only one way. So I don't think the AF-switch is in the wrong position I'm afraid. But thank you alot for the tips!
thanks a lot! I thought there was no way I could fix my lens but shes going again!!
Excellent video. Fixed stuck focus issue.
On the ribbon, a pair of twizzers will be easier to get it through the tight gap.
such excellent work detailing this process. you did great.
+Kristoffe Brodeur Thank you Kristoffe, means alot!
Christofer thnk you for the superb guide!!!
My 50/1.4 AF is not working.....i'll sit down and open it!!! cheers
Mr Cederberg:
Thank you for your video instruction. It is very helpful for me and I have subscribed your channel. I hope that you can give me some hints on my lens problem.
I have a Canon EF 50mm / 1.4 lens, which is exactly same as this one in your video. I accidentally dropped it onto the ground a few months ago and then found that I couldn't use auto or manual focus anymore. About a month ago, I fixed the problem by watching your video clip and the lens resumed auto and manual focus functions. But unfortunately, it worked not smooth and sometimes the auto focus stopped working and I had to switch to the manual focus,. Once I could use manual focus, the auto focus recovered. About one week ago, the lens stops working and I can't use either auto or manual focus. I tried again to fix the problem as the last time I did by repeating your procedure, however, I failed and cannot even turn the lens manual focus barrel. The manual focus barrel seems stuck by something. I had to dissemble it again but couldn't find any problem. Could you please provide your insight from your experience? It would be very helpful for me to find the problem. Thank you in advance!
Doug
Underbar video, räddade delvis mitt objektiv, nästa steg är att slipa på plasten på utsidan som förhindrar att objektivet rör sig utåt och fokuserar! :)
Vad kul! Det där låter intressant, kan också ditt objektiv enbart fokusera åt ett håll? Mitt har det problemet, dock blev det inte att ta tag i det vidare då jag har ett till likadant som fungerar.
Yay, my lens is fixed. I didn't think this would do the trick but it did. Thank you Christofer! I hope that you were able to fix your lens with a new motor.
Great! I haven't looked in to it anymore as I have a replacement. Will try to fix it again some day.
very helpful. The sliders were sticking, however I made it worse when I followed the advice by pressing the ring on a flat surface which coimpressed one of the slider grooves, so had to reopen by gently prising.. be carefull if you press on the ring to remove the deformation as described in video..... you can press too hard which squeeze the slider grooves too much which restricts the lugs from smooth operation... making it tight and thus manual and auto will not work. However all resolved eventually
I'm pretty nervous about attempting this, but after my lens took a fall causing the AF to become faulty, I think its going to be my only option as repairs are way more than the lens cost. This is a great video and I look forward to trying this out. Fingers crossed for me!
Actually it's not as hard as it looks. Just have something to organize the screws in. I used a old empty assortmentbox for small screws. Put screws in one appartment together with a little paper with instructions of where the screws should sit in the lens and in which order they should sit.
