Thanks, I've got also a copy with haze. With your video, I'm thinking of cleaning it myself!
Great, hope you manage without trouble, I think the video is explicit enough, but if you have questions, do not hesitate. Best.
Thanks for the video! Good work!
Thanks to you, don't forget to subscribe and tell all your friends about the channel.
Liked and subscribed. I just used your method to clean mine, it worked very well, many thanks.
Hi, very glad the repair went smoothly. Don't forget to tell all your friends about the channel. Cheers.
Nice job, It's interesting to watch someone else repair a lens you are very familiar with. I do things a little different than you but you did a great job.
Thank you very much. It means a lot coming from someone who has a lot more experience than me.
This looks really helpful. I have managed to remove fungus from lenses before but always struggled and failed to remove haze. So I will give this a try using your technique and see how I get on. Thank you very much for posting this.
Hello, it's just like fungus, you need a bit more patience. Best way to say thanks is liking, subscribing and telling all your friends about the channel. Cheers.
@@diyextravaganza thanks I've already done that
thanks!
You're welcome !
Hi I have these 35-70 af2.8 D, and I used them in the past on a Nikon D70, D300, F70, and FM3a and worked great . Did not use them for quite few years now I tried them and noted that the focus ring is not working the full range from 0.6 to infinity, it’s working only from. 1m to 3m , at both end of the range is not touching the end of the range. Would you please advise what could be the issue and if this is repairable? I live in Texas USA
Hi, first thing I'd try would be to remove the bayonet (remove black part first) and remove the focusing gear and try to move by hand the focusing ring, just to understand where is blocking. It is repairable but hard to tell without having a look at the lens. Cheers.
That's amazing, I'm ready to try it. Any issues w/ working loose later? Are you redisolving old glue to reuse & it sets OK? Wil this haze come back in back eventually even if stored better in temp control ?
Hi thanks, no, I don't use glue again, this is what caused the haze to start with. Haven't had any feedback of later issues and I've repairing this for 5 years now. Cheers.
Hi Thanx for the great video that gives some confidence when buying this lens. Question: I have my sight on a lens that is clear at the moment. After all these years; Will it stay like that or will the haze stillcome at some point. Regards from the Netherlands
Hello, I bought a clear one a few years ago, but the haze came probably after two years. So, I'd say it is inevitable. What you really need to pay attention is if the small group (the third assembly from the front, or second from the back), has haze or separation, less common but happens nevertheless. That one is a sealed element that you cannot open without destructive means. Cheers.
Very nice job...congrats! What you uses to disolve the old glue? Just Isoptopyl Alcohol is enougth? I have the same lens with the same problem and I will clean it like you done. Please let me know how you removed the old glue
Hi, isopropyl alcohol, 99.9% pure. That's all. Best.
I have one with some balsam seperation in the rear complex lens. Is there any way to clean it to fix it ?
Thank you.
Hi, you mean the small one, that one it's near impossible to fix as it has a metal casing. I've tried but it takes an incredible amount of effort to open. Finally, I've settled to buying 35-70mm 2.8 in unrepairable condition and keep those elements for replacement. Cheers.
is there a way to fix the front glass becaues mine has scraches on it is it possible to fix it and where
Removing scratches usually involves repolishing, which will remove the coatings, so, you need to recoat. Since the lens is a common one, that will probably cost more than buying a "parts" lens. This is what I usually do, I buy copies beyond repair and recover the parts. I think I have one front element, I can sell it to you but it will depend more on where you live to see if adding the shipping price makes sense. Best
Con que producto exactamente lo limpias
Hablas de la bruma? Utilizo el Hama Htmc, creí mencionarlo en el vídeo. Saludos.
I’m planning to do it. But there was glue on the internal element. How did you replace it.? What Kindle of glue?
I did not add new glue. I keep it as is, so if I need to come back I don't struggle and avoid risk of having the problem back. Cheers
@@diyextravaganza Thank you, I will do it👍
Hello.
I tried but I forgot to mark the position of the focus 3:11 and can´t turn the focus to infinitus... Must I do it by trial and error?
Hello, sadly yes. To gain time in such situations, I put some paper tape on the lens and mark each entry position, so I'm able to discard all the wrong solutions. It takes time and patience though. Cheers.
thanks a lot! @@diyextravaganza
Hi Man! I disassembly the lens as per your video, very nice and good help...but I tried to remove the haze from the same element like you but it continue on the lens surface after clean twice. It's normal or maybe need adittional works or products? By way Ibidentify small fungus on the lens near on bayonet...can you help me on this?
For the haze, you need to do many many times, it will go away eventually. For the fungus, can't you add a little video on your CZcams? Best
I'll do the vídeo and post here after

@@fabiosales2985 Hi, I saw, for the haze, you'll need to insist on the cleaning, the next group is tricky because it is sealed and near impossible to open, I usually replace it altogether.
but that is in the front element, what about the back element?
There are two "back" elements. The one next to the bayonet is easily serviceable, the next one is a sealed element. Impossible to open without doing some damage. Cheers.
@@diyextravaganza Thanks.
My upper only element came loose not the whole lens group like yours. I think this method is very hit and miss. I did not have that much luck.
Yeah, that happens sometimes (I think I mention that on the video), just keep going. Cheers.
🤬🤬🤬🤬To the person who sold me a hazy lens on marketplace
No need to get angry, you can fix it now. Cheers.
@@diyextravaganza after watching your video I will now, because other videos shows 1 hour plus so I said forget about it.
