First of all, thank you for the video, it helped me clean a very dirty lens that I couldn't use and that I didn't think I'd be able to ever use.
If like me, you can't get rubber cone, you might want to try an empty toilet paper roll instead:
It has an almost perfect diameter for the task, but lacks the grip. To overcome that, I wanted to add double sided tape on the internal diameter. But since it won't stick well to flimsy cardboard, I had to first cover the last inch of the cardboard with glue (I used polyethylene), and after it gets dry (1-2 hours) I added the double sided tape.
You want to get to a state where you have to push the TP roll hard onto the lens, so that it has a good grip. Once that was achieved, unscrewing it was very easy.
excellent tip, thanks for that.
Thanks, this helped me fix my beloved lens!
Very happy it helped you. Don't forget to mention the channel to all your friends. Cheers !
THANK YOU SO MUCH! I'm inspired to d surgery on my hazy Tokina 28-70mm again. I and a repairman have tried to clean the haze that is in between elements without any luck. He used acetone to remove the glue in a group of elements but that did not work. I'll try alcohol to soften and remove the glue once I get free time. BTW I'm only keeping that lens because its a very rare non extending 2.8 zoom. All my other zooms are like that (Tokina's 11-16mm and 50-135mm.)
Thanks! I'm glad that you feel inspired from my video. It's better to take a go for it than having an expensive paperweight!
Tip for putting the front back on. Put the top ring in the infinite position and then mount the front in such a way that the screw hole becomes visible through the outer opening. This way you restore the full range of focus from 0.6 to inf. So vary your starting point for screwing it in, until you get the alignment right
Thanks for the tip
It is no easy for me. I could do it but it doesn´t get the infinitus point.
Great video.
Thanks
Great video ! I would never dare disassemble a lens :D last time I tried with an old Jena, I couldn't rebuild it (and I still can't.. )
lol, I have got some Epic fails myself, so cheer up!
Hi, great video, thanks for posting. One comment - I think I saw another video by you, same lens, but in Spanish. In that one you marked the front element and body together so you could put them together in the correct place without trial and error on the helicoid position - is that correct ? thanks.
Yes, it is an updated version, it exists also in english. czcams.com/video/xfPtJXFAxPA/video.html
I hope you can share before and after photos for comparison
I was just checking but I did not keep the only photo I made before fixing it. But believe me, it wasn't good.
Hi, I am following your instructions but the inner lens won't turn and come out as in 9:20. I am using your recommended Japanese rubber cone. Can you suggest me some options to loosen that lens, thanks!
Patience. Sometimes they don't come immediately, you need some patience. If you can access, you can put some alcohol (or acetone free nail remover) into the threading, it makes it easier to get it loose.
hello Sir ,Do you have instructions on 35-70 mm Nikkor Ai zoom lens.Thank you very much
Hello, no, I haven't but I have one waiting to be repaired.
Thank you for your video. When you unscrew the group you have an element ( the one you cleaned) and an other element or an element ( the one you cleaned) and a GROUP ? Mine 35-70 has some kind of balsam seperation and a technitian told me that is Unfixable Thank you
you mean the small element just after the one I cleaned?, if yes, the technician is right, it is very hard to fix. Best is to replace it.
@@diyextravaganza Yes I am talking about it. Is it a Group i guess ?
@@DimitrisPapadopoulos1980 yes, it is a doublet, thus the balsam separation. I tried that repair once, but abandonned it since it was too complicated to perform and found a replacement online (out of a dead lens).
@@diyextravaganza Thank you once again. I am after a good group for my lens too..
What the name of liquid do you use ? Thank tou
isopropyl alcohol 80-90%
Hi, I am from Argentina. So sorry for my bad English. One technician recommended me no tu use it in my D750 because in the future the lens will be affect some parts of the diaphragm system and the focus motor/engine. Do you know something about this? Thanks in advance. Regards.
Hola Daniel, hablo español tambien, el tecnico te recomendo no usar el lente pues va a dañar tu camara? La verdad te esta diciendo mentiras, seguramente para venderte un lente reciente. Saludos.
@@diyextravaganza Me dijo que la D750 es una fina y delicada pieza de
ingeniería mientras que el 35-70 fue diseñado para los cuerpos de cámara de su época, más fuertes donde hay más metal y menos plástico. Recomendó utilizar la lente en este tipo de cuerpos. Y por cierto, Feliz Año Nuevo y gracias por tus respuestas
@@danielrfunes jajajajaja, que gracioso este hombre. Si la camara tiene el tornillo para hacer funcionar este tipo de objetivos, asumo que es para usarlos, no? Feliz Año Nuevo para ti tambien.
@@danielrfunes Ese técnico es un pelotudo del orto (acá en Barcelona los catalanes aprendimos a hablar argentino ;)
La D750 se diseñó con motor de enfoque pensando en usar los objetivos de los buenos viejos tiempos y lleva una buena montura F en metal, qué otra parte va a tocar el objetivo?
The hardest part of cleaning this lens. Is removing the middle lens group...persevere and it will come out....
