As far as I know removing the front lens element requires special Nikon equipment and training to put back on as it requires calibration. If not done then lens will work but soft at 2.8 wide open.
Thanks for the video. How do you know if the cause of the autofocus problem is caused by motor issue and needs to be replaced or just dirt and needs only cleaning?
Thanks. I have no idea the reason for the fault. Just know the auto-focus does not work. I try to clean it th-cam.com/video/8Eo2FtqRoes/w-d-xo.html and still not working, so I think I have to replace it.
This is probably the most in depth and informative repair video for a Nikon lens that I have ever seen! I would like to see you do a disassembly/repair video on a Nikon AF-I telephoto lens. These lenses used coreless stepper motors for autofocus. Anyway, these motors have been long out of stock for years. However, there are various companies who manufacture these small stepper motors (including Canon). I know a stepper motor can be used to fix an AF-I lens and it would be cool to see it done. BTW, do you have an address where I could send my broken lenses to have repaired? Thank you so much!
Thank you. Unfortunately, I don’t have a AF-I lens. I think that’s rarely find the parts for a grandpa lens. You must a hardcore user of Nikon. I hope you can fix your lens. Good luck!
@@LeighSr Luckily nothing has broke on my AF-I lenses. I bought some pretty nice shape lenses and only baby them. I don't use them hard. However, it is a known fact that the motors fail. Nikon outsources components like any other tech company. Foxcomm anyone?! The motor inside these lenses are just that. A simple stepper motor so I know it can be fixed because such things are still made to this day. Canon actually makes stepper motors for their copy machine division. After watching your video, it just gets my mind reeling. I don't like a camera company telling me I cannot repair their product when I know the parts are out there to repurpose. You are the kind of guy who has the skills to make something like that a reality! Thanks again!
My autofocus gave out after 8 years. Thank you so much for this video!
非常感謝你，多得你的影片，我在第一部分打開對焦環銅片時，只是摟動幾下，對焦功能就回服了！
Just bought a defective 24-70 2.8 and I'm definitely going to try this, thank you for the great video ! 👍💪

Hello, there is fungus on the inner inner lens of Nikon 24-70mm 2.8 N lens. Do you have a video on disassembling the inner lens, thank you
Thanks, its works! But I need 2,5 hours :)

Hello, do you have any video where you clean the fungus lenses of this 24-70 lens? mine has fungus inside, thanks!! I am in Argentina
Sorry, I don't have the video but followed the video you might do it clean.

你更换马达的技术太专业了。前两天我的尼康500mm f/4E 镜头拍照时还对焦，从相机上取下来再装回去就不对焦了，按动快门镜头没有任何反应，换个相机也是一样，请问您有用电表测量镜头触点的视频或经验吗？如何确定是马达问题？我这镜头的马达在哪里可以买到？非常感谢！
您过奖了！这是我第一次修理镜头，我是经过拆解清洁后不见好转，然后又到网上搜罗，找eBay的商家咨询之后才确定是马达坏了。最后马达是在eBay上买的，国内的卖家。
@@LeighSr 谢谢您提供宝贵的经验。我住在西雅图，请问您住在哪里？
不错，厉害，看到了，这一集把镜头对焦修好了，我也是同样的问题，不过不知道，自己换对焦马达镜头对焦还有之前的精准吗？我的D800镜头也坏了，正在考虑要不要去维修。
我试了试没啥差别。如果有差别可以在相机里矫正过来。
没多出来个螺丝 差评 哈哈
