How To Replace: Bayonet Mount on a Nikon AF-S DX 18-105mm f/3.5-5.6G ED VR nikon lens repair 

I so appreciate the simplicity of this video. No unnecessary graphics, no introduction that takes up 5 minute to actually start showing what the title said it would, no sharing of any personal stories that were uncalled for, no stalling of any kind. It showed exactly what I needed and nothing more. Now my camera works! THANK YOU.

Great video. Thank you! Couple of points (having actually performed this fix on precisely this lens following this video). That tiny pin that is attached by a wire to the inner right of the lens (as unscrewed at 4:00) is a four-piece spring-loaded pin. If you pull gently on the ring, the wire can separate from the spring loaded pin. If this happens, it is only a matter of tiny knocks before the tiny black plastic insulator ring is fired across the room. Work in a clean space to avoid losing parts. If you do separate the wire from the spring loaded mount, you will need to solder the wire back on to the spring-loaded pin. Because the "open" spring makes it impossible to do this, thread a piece of cotton through the middle of the spring and tie it tight. Put the pieces back together, solder it up and then cut the cotton. The iFixit Essential ElectronicsTool Kit was extremely useful in replacing the broken mount ring.

This is a great video - needs no words, super clear and works!! Recommend magnetised screwdrivers and attach spring before remounting ring so that the spring is only under tension when attached at both ends and so less likely to ping off!

Be very careful of that wire. Mine broke too but was able to strip some of the wire and use the compression ring to replace it. Works again! I will never pack my wife's camera in checked bags again!!!!! :)

Very useful. I had a problem in that on my lens, as I tried to remove the aperture stop down rod/ring (as you do at 3:50 on the video) I could't take it out; it was still retained deeper in the lens, so I had to remove the two screws that attached the rod to the ring. The screws had thread-lock applied, so I had to reapply it to make sure they stayed and didn't become loose. Fiddly to reassemble, but all good in the end. Thanks for that.

Thank you, now have my favorite camera back! For those of us with bad eyes, a magnifier is a must. The screw for the spring loaded clip was the hardest for me. I ended up breaking the little wire too and had to solder it back on. Also, all kinds of shims will fall out if you turn it upside down to get dropped screws out! They have to go back in a certain way. One thing that made it easier for me was to turn the lens so that the glass portion drops a bit. Didn't have any issues with that tricky part with all the contacts. Took me about two hours I guess, but mostly because of just having bad eyes. It was a great learning experience, would do it again! Made sure to clean the inner lens followed with a good blast of compressed air to get any bits of the old ring out.

You saved me lolI took my lens to Mike's camera to see if they could fix it for me and they told me no that it was useless now. Said I might as well just throw it away. I couldn't do it. My lens has been broken for so long. Thank you sooooo much :)

Thank you!!! Thanks to your video I managed to replace it and have my lens working back!!! Great video!!

Great video. Watched it through and then followed it when doing the repair. My comments echo an earlier poster. Should use a Phillips head screwdriver. The wire is attached to the pin with the black ring. If it becomes separated, remove the ring, put the end of the wire in the ring and feed it back onto the pin. Reassembly of the two inner pieces is easier if done together. Thank you for your post

Excellent vid. I dropped the exact same lens which resulted in the same damage. I considered buying a new replacement but then thought about repairing my own. This vid has encouraged me to give it a go - Many thanks.

Life saver . Thanks a lot buddy. I was able to fix mine. Although I snapped the thin wire accidentally and had to solder it. Was a pain in the ass but all is well in the end

Thanks to you I managed to fix my lens! It was tricky but worked with patience!

Fantastic video! Got it done in 40 mins or so. Thank you

Superbly demonstrated! Copied your recipe and fixed my lense :-)) You are a gift to humanity ;-) Tip: I found it even easier with magnetic Philips screwdrivers.

Thanks for the video, showed what i needed. Incredibly good pointer Toby Haynes, work in a clean space. I dropped the screw that holds the brass bracket on with the spring loaded wire / ball point / contact point thingy and thought the screw fell further into the lens. I got way more intimate with the lens than I wanted to but saved me money on a new lens!

EXCELLENT video. Looks very easy when you did it. I found the tiny screws fiddly and took much longer, but worked brilliantly. I was quoted 60Pounds+VAT! Bayonet cost me 2.99 on Amazon. THANK YOU!

Video semplice e perfetto da seguire passo passo. sono riuscito a sostituire l'attacco a baionetta rotto senza difficoltà anche se non avevo mai messo mano ad un'obiettivo Grazie per il video

Many thanks. Just fixed my lens for a second time using your video!

Your old bayonet ring looked JUST like mine! Nikon engineers have work to do.

Between your great video and my daughter's small dexterous hands, we were able to replace the bayonet mount ourselves. Thank you!

Great video, saved me a lens- thank you very much!!

best explained without a word good work

Great video! Bought the mount on Amazon. Rubbed the screw drivers on a magnet to make them magnetic, worked great! Thanks!!

Awesome! Followed your steps and managed to replace the mount ring on my lens!! Thanks a lot man!

Thanks! Way better video quality and angle than all other tutorial videos. I can actually see what you're doing.

Your video was concise, easy to follow and well made. Thank you for the expenditure you saved me if I had shipped out the lens to be repaired. Kudos.

Thanks. This was very helpful. I would not have tacked the job without it. Its really quite fiddly. Now have a working lens again. THANKYOU

Thank you. I just got myself a free used lens thanks to this since the previous owner wanted to throw it away.

Thank you, I managed to change my Nikon bayonet by following your steps.

Totally saved me from dorking around with shipping this back and forth to Nikon. Of course, if I'd taken pictures as I was taking it apart a couple weeks ago... Awesome video though. Maybe have We Are The Champions in the background!

this is LITERALLY the EXACT spot where my lens broke LOL i mean at this point are they meant to break this way? thanks for the video man

You have VERY steady hands!!

Very nice TY the Macro action is awesome and imparts confidence to the viewer

Excellent Video. Explain/shows each step in details. THANK YOU. It worked with 100% perfection.

Excellent video, followed your steps and was able to fix my 18-55

Thank you very much, saved me a lot of money. But nearly got a nervous breakdown, when the small cable teared off. But was no problem to solder it. (sorry for my bad english :-))

Fantastic, clear video! Tricky with all the tiny screws but worked perfectly. Thanks very much!

You r a very good man.. Because of your vedio I save over a 50 dollars.. Thank you from my heart 😘😘

Thanks for an excellent video that helped rescue my lens!

Great video, good clarity. Really nice to have such a close up view. Took me longer than I thought but everything works. Thanks again. Appreciate your effort.

Hee Luuc, bedankt voor je super filmpje! Het is me door jou gelukt mijn lens te repareren. Je moet het objectief vanaf begin in 18mm positie zetten, heb ik ervaren.

I was able to replace the mount using this video! Thanks a lot!

Fantastic instructional video! Lens repaired.

Excellent video. Helped me fixed my lens. Thanks.

i thought i lost my camera for good once this oart broke on my nikon d80, but this video really helped me

Thanks! Works great again.

Excellent video!!!

Excellent video demonstration, will post result after the deed is done.

Terimakasih telah berbagi pengetahuan...goodjob

Good job nikon with it mounts. I accidentaly drop my camera. If it was made from a metal mount, my lens will be teared apart. God bless only the plastic mount is broken. By the way, what is that little cable do? I snapped it and worried.

Thanks. Extra precaution needed due to the small wire. Mine broke while double checking the spring course. I managed to weld it back and it seems to work fine now.

Great video!! I replace mine watching it. The only thing, you could advice to be carefull with screws, because they are no all same size. Regards from Argentina!

Thank you so much for posting this! I just fixed my favorite lens!!

Merci pour cette vidéo. Elle m'a permis de réparer mon objectif que j'avais malencontreusement fait tomber, et ceci pour la modique somme de 6 € ! Les grandes enseignes photographiques me dirigeaient plutôt vers un nouvel achat.

tysm for this video. i jave the same problem with my 18-105, this will help me a lot.

Thank you!!! You saved me!!! I broke the Little cable but it work perfectly even without it...

Easy to follow and fix myself, thank you!

Many thanks, very usefull video.

Yes...I fixed my Nikon lens. Thanks a lot!

Where can you buy the new mount? Thanks great video!

I’d suggest using a magnetic head on an telescoping rod, as used by mechanics. They make small ones that fit in a shirt pocket, with very strong magnets. Much easier than tweezers for removing tiny screws.

Thanks!!!!!!!! Easy to follow! The best out there!

Great video , can you please help me , what screw driver shall I use as really tiny screw can't undo please help thanks kindly adam

Thank you! It is a great helper.

Thank You, Thank you woooorale much for this video. The job looked intimidating but I was able to do it with your help! Thanks!!!

My lens is the NIKON DX Nikkor 55-200 AF-S 4-5.5 ED. Where can I get the mount part? I’ve always been pretty good at fixing things and your video is just perfect with telling how to do this - I think I can do this, but I don’t I need them out for that specific lens? How do I get that?

Thank you so much for this. Huge help!

Very helpful and well done. Thank you for sharing!!

Thank you very mutch for your help, from Barcelona yours sincerely Lluis

I have a question: I followed all the steps on the video, and it was easy, but now all the pictures that I take are very dark. No matter if I set the ISO all the way up. It's like the lens is not allowing the light go through it as efficiently as before. I had to change the bayonet because I dropped my camera... could it be that there are other components inside the camera that are misplaced as well because of the fall? Does anyone else is experiencing this same issue?

Excelent. Broke ground cable. Time to solder back on. Is there a specific order to the rings? Bumped off and assembled back on aliagnment, but there are 2 gold and 2 silver. Attaching the spring took almost an hour.

Muchas gracias!

Excellent video man :) Thanks alot for it

Fantastic video! Fair play!

I would strongly advise anyone attempting this sort of repair to invest in a set of JIS screwdrivers (Japanese Industrial Standard). Ordinary crosshead drivers are not a very good fit and you can start to damage the screw heads, making them impossible to deal with a second time. JIS match the screws the Japanese use, and make the job easy(er).

Hey thanks a lot for making this video helped my out for changing my mount

Hello Luuc congratulations for the video, I wanted to ask you, that delicate thread to attach to the bayonetta, what is it for? thank you very much

Great video you just save me a lot of money!!!

Thank you

Thank you bro

This is a great video. I've gone through it, but think I did something wrong... when I telescope the lens in (i.e. reduce zoom), there's a bit of friction/clicking. Any ideas before I take it apart again?

Very helpfully, thank you.

Great video thanks! where can I buy this spare part ?

great tutorial, pitty I managed to break the cable at 6:40 - it's very fiddly (in fact my new bayonet had a smaller hole for my original screw, which I found out after cable snapped), but it seems lens is working without it, not sure what that thing is for ...

magnetic screwdrivers work well

En Amazon podré conseguir esos destornilladores??? Ayudaaaa

Does this fix the problem of the camera not taking a picture with this lens?

Ok. So a replace the mount ring and thought I was good. Put the lens on the camera and now it won’t come off. Any tricks??

can i use that with AF-P NIKKOR 70-300MM 1:4.5-6.3G ED???

Thanks a lot! works great!

What for a small cable is it in the f mount?

can someone tel me . which screw driver size should I have to open those 3 different types of screws ...plz help me out

Thankyou brooh❤❤❤

Thanks for saving me $110...Awesome!

Awesome job! Great clarity also. Send me your address and at no cost I will send you a magnetized philips head driver.

What is the cost of bayonet mount of 70-300mm lens mine is broke a little bit and doesnt fit in the camera it falls off

Thanks for the vid but I hit a snag right at the end. When I put the last ring into place it seems to foul the sprung section so now the lever will not snap back into place. Anyone any ideas? Otherwise it all fits fine.

Thx bro . Good work

Hi. Can you advise on where to find the new ring?

THX!
