I would just try to see if I could remove A LOT of old fungus with Hydrogen Peroxide 3% in my old Pre-Ai Nikkor 50mm 1:1.4.
And it turn out to be very good, after that I clean the lens element's surface with lighter fluid, just to take away the rest of residues.

I've always believed that you should know how to work on the equipment you own.your video not only taught me how to clean these lenses, but it also taught me how to get them apart to work on them a lot better than a lot of other videos I've seen. And with basic tools that anybody can get their hands on. Thank you for such an informative piece of content.

I love how simple these old nikkors are built. They are very easy to dismantle, after you take each part out it looks like you are doing it on your own without much thinking. After I cleaned my 55mm 1,2f Pre AI it felt like I knew exactly how to dismantle it while I was doing it for the first time. Cant say the same thing about Russian Helios 44-6 for example... Quite tricky focusing helicoid, easy to take out hard to set it back correctly.

When re-inserting a lens into its retaining ring you should *always* place it on a soft pillar and then lift its ring up around it until the lens lifts off the pillar. The retaining ring must first be placed the correct way up on the table and surrounding the pillar. The pillar can be anything smaller than the lens but soft enough not to damage the glass lens. Tissue will easily protect the lens from the pillar. A shot glass or a small plastic container will do for a pillar. Dropping a lens into its retaining ring is very likely to make it twist and it may lock solid and even chip the edge! Edge chips are very common on old telescopes.

Hello. I worked in a camera repair store in Washington, D.C. for a year fixing cameras, from cheapo snap shot, to Leicas and Exactas. The lens technician, very nice quiet guy, showed me some of his repairs and cleaning lenses. From what I remember, he never used lighter fluid on the actual glass element, only glass cleaner. Lighter fluid is an oil, and leaves a film on the surface. So, unless you clean that off, it can change the performance of the glass, and may actually promote fungus or clouding. Otherwise, a nice tutorial, and I will have dig out some old lenses and try this. It makes so much sense to use peroxide, but I have never heard of it.

@birdtower2801 4 жыл бұрын

I'm sorry but you're wrong about lighter fluid. Lighter fluid, as all petroleum distillates, is not an oil. Quite the opposite actually: they are very good solvents, furthermore, they evaporate quite rapidly, so there's no need to wipe them off. That said I don't know if lighter fluid is adequate for cleaning lenses.

Excellent work! Thank you for that very useful tip. I have a Nikkor lens (35mm - 70mm F2.8) that someone sold me a year ago and they misrepresented the extent of fungus damage. In fact, they claimed it had none and their images of the lens were taken in such a way as to not allow the bidder to see the fungus. Long story short, I should have just returned it but for some stupid reason, I just complained that it wasn't worth the price I won it for and suggested that I would keep it if he refunded $50 of the $250 I paid. I think I was tired and thought he would object and reject my counter offer. Then I figured I would send it back and be done with it. However, he accepted the counter offer and refunded me $50... I am now stuck with a lens that I couldn't sell for 1/10th of what I paid for it. I'm going to try to use that cleaning process. I have many tools and am a first class machinist (retired) by trade. However, I'm going to have to find a set of rubber cups like those that you used to unscrew the various lens sections. I need to see if you happened to list where you got those from. I should be able to find a spanner wrench somewhere but if I can't, I can always make one. The 35-70mm F2.8 lens was a good lens in its day but the fungus really made it practically useless. The camera I shoot with most of the time is heavy enough, (Nikon D4S), and this 30/70mm lens is quite heavy for such a small lens but I may keep it if I can clean it. Thanks again, Rich

This is interesting! I pulled out my Tassco spotting scope last week and to my surprise the zoom eyepiece was sporting the same symptoms. Didn't know what it was other than moisture related. Cleaned affected lenses with just glass cleaner and allowed them to dry. Reassembled and no issues. Now that I know its fungus relatedI I'll bring out my UV Prom chip eraser and let it shine down the apertures from both ends for a while followed by placing it in an airtight container with silica gel kitty litter that I have dried even better, fresh out of the bag and holding in a sealed mason jar until I need to use it. Great video, one recommendation is that the retainer ring used on the last lens group appeared to have been scratched when the dividers slipped. You might want to give it a coating of lamp black or what is more commonly called soot. You can use a tall candle flame that is smokey and give it a coat to kill the shininess of the metal. This way you will not experience strange reflections within the lens.

I've used peroxide...but I have to say this is the first time I've seen lighter fluid used for cleaning. My final cleaning is always with acetone or methanol. You've shown me something new and interesting and for that I thank you.

Fungus spores create hydrofluoric acid. It is so strong, it actually etches the glass itself. Hydrogen peroxide can remove superficial fungus tracks, but cannot undo the damage to the lens surface. Or to the lens coating, which will be removed by attempts to polish the lens object. Carl Zeiss recommends you avoid use of air-tight enclosures or organic material in cases. I use neoprene lens pouches. Zeiss also suggests UV radiation (as in noonday sunlight) to front and back lenses openings periodically. I expose my lenses to this treatment a couple times a year, since humidity is not high here and I don't tightly seal my camera equipment cases, but allow a little airflow. In the tropics, UV treatment probably should be done monthly. 15 minutes is probably enough. Desiccants have been used for years in camera cases and in shipping containers to retard growth of fungus spores. Camera stores look for fungus tracks before taking a lens on trade. Unless the lens is rare and valuable, fungus in a lens makes it unsaleable or suitable only for the mechanical parts. Its value is greatly reduced.

My personal secret ingredient which has succeeded in removing every fungus I've come across yet (though admittedly I've only removed fungus from a dozen lenses or so)... a q-tip with saliva, followed by a good clean with other cleaning agents afterwards of course. Haven't tried hydrogen peroxide yet, but in my experience it works significantly better than isopropyl, lighter fluid or Eclipse. (Of course this potentially won't remove all spores etc., but it makes the lens perfectly useable again)

Nice! I decided to try it on one old Canon wide converter (it was totally covered in fungus), and with Saliva they all went away. Now it's very good, actually. Something to research about.

For 500m toklin lens,the screws are so small just be careful not lose them make sure you have eye glasses screw driver kit any drone screw driver kit will work just Popsicle stick to get rubber black off you can small screwdriver on it them use Popsicle stick on it will slip off the lens make sure you have photo squeeze blower kit with brush get dust out of the lens and mirror lens and the mirror.

fungus are very weak organism.. they are easy to remove just mecanically, peroxide is oxygenated water so is pure. the hardest part with optics is to reassembly togheter exactly the way it was. and your meticulosity did work on there :)

If you don’t clean the barrel, isn’t the fungus just gonna grow back again? It probably has spores around it, yes? Love your videos , so suspenseful.

You do not need to disassemble the diaphragm to clean the rear lens, just unscrew the front part and then open the diaphragm to clean the rear element

Excellent video, I didn't think I'd watch all the way through as my lens doesn't have this issue...then I got hooked. Great stuff. You wouldn't know how to reset infinity focus on this lens do you? I bought exactly the same lens as you have there, it's immaculate but it won't focus beyond around 7 metres wide open.

I have already made a video about how to re-grease this lens, so maybe it can help you, you can see it right here: kzfaq.info/get/bejne/oLGFlNNm1dixeWw.html
