Remove old fungus in Carl Zeiss Planar T* 1.4 / 50 with Hydrogen Peroxid and lighter fluid C /Y

[@stanleyshyeoh]

I paid an expert to clean this lens years ago. He did great work. Now having watched the process of cleaning, I am convinced what I paid for is a bargain.

This is really great content, thank you so much for posting this. I love the immense amount of detail and explanation.

Thanks for sharing. With your instructions and right tools, it is so easy!

Love watching your videos. They are encouraging and very very helpful. Thank you!

Hi, is there a way to disassemble lens groups like at 38:10? A different lens of mine has fungus (or fingerprints?) inside this group and I have no idea how to get to it.

[@LorenzSimnowski]

Is it possible to take the lens out at 38:00? I need to re apply the lens kitting because ist destroyed :(

[@yvesdanis6049]

Hi, love the video. Can you tell me if the 1.7 planar can be cleaned the same way? Thanks

[@mikeno62]

I have try to cleaning the front lens group in the Carl Zeiss 50mm 1.7 Planar, but it’s not the same way just like the 1.4 Planar. I will see if can get the time to show it in a video sooner, but I’m too busy at work at the moment.

[@rutsae-eng6387]

I have a hasselblad zeiss CFE distagon 40mm. Could you please let me know how can I remove the rear lens group so I can do some cleaning? I tried to search online but haven’t found and VDO. Thank you in advance

[@_JoseLucatero_]

Hello Mikeno, beautiful video by the way, wanted to ask, I bought a carl Zeiss Distagon 2.8 35mm and has a tiny bit of fungus, would the lens I bought be similar in taking it apart like this one in the video? Thank you so much for your time.

[@insertusernamehere.9489]

Do you have any tips for getting sand from the beach out of a lens? It jammed the focus and now my focus ring won’t go all the way in to the ♾️.

[@mikeno62]

Hmmm 🤔 it’s not good, because if only one sand corn gets into the helicoid thread it will be almost impossible to guess what way one should turn the focusing ring so it will come loose. But on the other hand you could try to disassemble the lens as much as possible from the front or/and the back, and NOT turning the focus helicoid, then you can try to use some cotton buds and wipe out as much sand corn as possible. BEFORE disassemble the focus assembly you try to measure the focus assembly. Start with the inner helicoid and set marks when you ( hopefully ) can get the helicoids apart. Then you can try continuing with the next helicoid and so on.

[@dritzzblitzz]

Thanks for this good tutorial. I try to clean it but forced too much when open the lens, so my diaprghm (aperture) pin become broken. Can you share if it is a way to change that pin.

[@chicobraz4335]

Thanks for this,any chance you can show how to fix stuck wide open aperture on sonnar 85 2.8 mm zeiss ?

[@mikeno62]

Sorry, I do not at the moment have a Zeiss sonnar 85 / 2.8

[@ziggozwolle]

Don't you remove the coating on the lens this way, with the hydro-peroxide?

That exactly what I was thinking

[@matan7986]

How about meike 23mm fuji mount?

[@georgialeksandroff9370]

Hi nice video I have a question can I use just ethanol for cleaning the glass

[@mikeno62]

Yes, I also use "Eclipse" lens cleaning fluid, it's also with Ethanol.

Any tips getting lens elements back into their retaining rings without them falling out? Are they traditionally cemented in?

[@carlono1]

Hi mike! Your video is super useful, thanks for your effort to help the people using old camera equipment. I recently bought a planar 1,4 50mm for just a few euros, it‘s full of fungus and dust and needs some cleaning. I‘m using the same vaccum pads like you, but i can‘t remove the first ring (the one with the „carl zeiss planar“ writing on it. Do you have an idea how I could remove it when it‘s stuck? I think the camera got wet some time and everything is really stuck together. Thanks for replying, keep up the great work 👍

[@mikeno62]

Thanks Carlo, about the stuck nameplate/front plate, in many of those old Carl Zeiss from that time they use a lot of thread lock and it was the red type (the hard type!). You can try to soften the thread lock with some nail polish remover with Acetone or Isopropylalcohol 99% or so on a cotton bud. Take really good care when use the Acetone on plastic because it can soften or destroy the plastic parts, just like many lenses with plastic front plate, and never use Acetone on aperture blade that are made of plastic...!.

[@carlono1]

@@mikeno62 thanks for the reply! I will try that. How are youre experiences with cleaned lens? I‘ve contacted Zeiss and they told me, fungus would be spreading easily and can even „infect“ your camera body or other lenses. Have you ever experienced something like this?

[@cinemapersona6001]

@@carlono1 Did you succeed? I have the same problem as you... I tried to put some on but it doesn't work

[@like2view]

I admired your "lens spanner" Where did you get it.? I have a much more cumbersome tool..this "compass" like tool looks robust, A side bit I have this lens and my baby boy pulled the camera off the table and it fell and badly bent the attached filter. Icouldn'T get it off for years.. finally one day with those work gloves I gave a try and wow great .. I was turning the front retaining ring and well . I was late able to get those two pieces apart and.the filter ring was not too dented. I worked it out with a ring tool ..slowly and now it's good to go...no visual fungus..lucky me

[@tsproduction2010]

Anyone know anybody that can change the iris mechanism on Planar to 12 or more blades?

[@matthewforrest999]

Hi there, Could you give me any advice on removing the front name plate? My lens has fungus and I've tried everything to remove the plate using the same tools you have but it is solid and won't budge. Thanks in advance.

[@areiacreations]

Some lenses open right up but some others don't. I have also been trying for weeks and tired my wrists so much from extreme attempts to open a couple of stubborn Contaxes. If you search for "bottle jar opener" or "Anti-slip Can Lid Opener" you will find some nice adjustable rubber belt openers that are used to open tightly sealed jars. I could open those stubborn lenses using that tool in 10 seconds.

[@matthewforrest999]

@@areiacreations thanks for the info, it turned out that there was excessive amounts of red threadlock holding it together, and used two rubber strap wrenches to pull it apart, what a job it was.

[@JKoehr27]

​@@areiacreations I've recently used a small amount of electronics cleaning spray to temporarily loosen some stuck focus rings, I wonder if it would help loosen the grime under the name plate.

[@jufegom]

Excellent thanks

Hello, Hydrogen Peroxid was not enough. What is the diference between using Hydrogen Peroxid and lighter fluid?

[@walterherrera3733]

Can you please disassemble a Yashica ML 50mm f2? Trying to do it myself I think I broke the lens :(

[@calowned]

Thank you for this amazing video! Can I ask - do you use different cleaning materials for different lenses? Or would you say these materials are safe for all coatings?

[@mikeno62]

Thanks, well It's just my own experience when working with Hydrogen Peroxide 3%, but some people said that some older Zeiss lenses have a softer coating than other lens brands.

[@aleclyons5755]

Thanks for your amazing video! Is taking apart the rear element grouping the same process on the MMJ version of this lens?

[@worroSfOretsevraH]

Hello. Do you have any experience with dust between lens elements in point and shoot (pocket digital) cameras? Is it possible to take apart the objective, or it is all glued together plastic? (It is a Fujifilm F40fd in my case) Thanks.

[@mikeno62]

It is possible to do, I have clean the lens elements in some pocket digital cameras and it turn out to be very good. One have to be careful when disassemble the camera because of the very thin flex cables inside those cameras and also on the side of the lens block, and even more careful when one open the lens assembly. TAKE good care of the flash capacitor, it can give some nasty sparks if you touch the 2 wires. Also because the plastic is very thin. But of course it is possible to clean with Isopropylalcohol 99%, NEVER use Acetone because it will damage the plastic parts. Try find a service manual, and take pictures during the process. There are many guide arrows inside the lens, where parts have to be disassembled or assembled so its correct. Good luck :-) Cheers Kenneth

[@GoodPitchers]

Have you taken any of the macro versions apart??

[@FILM-O-RAMA]

Hello Mike, Great channel I have lead a lot. I wonder if you are open to receiving lenses for repair. Do you only do this as a hobby or do you accept lenses for cleanings. Thanks again for this great channel. Best. R

[@thomasleoncomedy]

Can you please tell me if cleaning with these materials-- hydrogen peroxide and lighter fluid on the inside elements will damage their t* coating? I've read that they are very easy to accidentally destroy

[@areiacreations]

None of those materials will damage the T* coating, including acetone, alcohol, lighter fluid and hydrogen peroxide. I had elements submerged for days in those difference substances, in an experiment to remove hazing (which sits under the coating) from those lenses. None works and the coating in all cases is 100% intact.
