This is genius, why don't they use copper in the construction of lenses, maybe just a little bit on the inside somewhere. Would stop fungus from starting to grow.
I've disassembled a fair number of older lenses and I can remember two that actually *did* have a copper shim amidst the element groups. I didn't think much of it at the time but I wonder if that choice was intentional. Wish I could remember the specific lenses but I'm not sure - I think it was a Pentax-M and an older Hexanon but I'm not sure.
@@therealchickentender I had some Pentax lenses like that but I know mine were K / KA mount. The more common fixed focal lengths, 28, 35 and 50....I think...been a while......or was it the screw mounts.....OH WELL...I DO NOT have to deal with Pentax with really great digital at my disposal....no surprize "KLUNKY " shutter and no surprize backside popping open....or using a rubber band to prevent such.....lol
Also, it can work as a charm, as well, with already disassembled, old fungus infested lens *metal body*. Right? Only metal parts will go inside. Then clean it troughly (with similar solutions as with lenses), apply grease if needed, and assemble the whole system.
If you pay attention to older roofs covered in mold that have copper flashing,the mold is always much worse above the flashing.the rain washes over it therefore killing the mold below it.fun facts from a one time copper roofer.
Copper's a very good antibiotic. It'll kill just about any bacteria or fungi, and it's why some hospitals use it in high contact areas. Excellent advise Ken!
Wait, you mean copper scent can kill fungus because this is what’s happening here am I right? The copper when heated generates that steel scent and that’s it-Enough to kill fungus?
I recently brought a nikon z5 with 28 - 75 2.8 lens after few days it started getting fog and all pictures were coming foggy but when I brought the camera inside the house it used to go and all fog disappeared it happened everytime than I showed it to service center they told tht fog got trapped inside and they kept in dry cabinet after than I used it outdoors few times but I didn't noticed any fog but today I faced the same issue again when I went out it got fog but when I came back home fog went and I keep my camera in a air tight container with silica gels so now please tell me what I have to do will I need to buy the cabinet or what is the issue and permanently solution? Did anyone face the same please reply I am very worried it's only 1 month I brought the camera month.
Leave it in the sun for 5 hours? The heat will cause the lubricant particles to fog up your lens. Not a great idea. Clean the fungus with hydrogen peroxide.
Ken will the bag produce any condensation? And just to clarify please, if you have fungus already then this method is going to kill it, but not remove it?
I have a pre-owned lens with small thin fungus in it, it's not currently enough to have a noticeable affect on the optics but I want to kill the fungus so more won't grow. You suggested leaving the lens out in the sunlight, how long should I leave it for?
sorry, if you put it on a direct very warm sunlight at the window, and your intention is to make sure the copper get hot, then for sure that would be a problem on the lens blade oils, it will drip..
sorry for newb question: I am attempting to clean an old Angenieux zoom lens (12-120mm) and one of the elements gets fogged up on the inside when I blow it dry. In my inexperienced opinion I wonder if this lens is fucked. But like I said I'm inexperienced so....
Oh, are you referring to dryer or just spinner? I don’t have a dryer, that hot gas dryer. Only spinner, (the one that automatically after washing cycle) will that do? Oh wait- is the goal here to generate heat/steam like heat to copper? Can I just boil instead or put in an oven?
Hi, I have a Tamron 17-50/2.8 (no VC) with fungus on the rear element. After carefully searching in the web, I don't think it's worth opening to clean it since it may be extremely hard to assemble back the lens group aligned. Fungus is dead (UV). Do you have creative ideas on how to deal with this "dead body" on the rear element? Would this trick shrink or minimize somehow the amount impact (it's huge most in the center)? Do you have any other thoughts? Thanks a lot in advance for any ideas!
Even after using this trick if the lenses are fungus affected you can't remove fungus completely,but before attack of fungus on lenses this trick will save lenses from fungus
Another effective way to kill fungus is vinegar mixed with garlic (very good for athletes foot), but yeah, I dont think it might work as good for lens.Just asking, will scrap bits of small copper tubing and a hair dryer do the job too?
Albert Lin , Put your phone in a ziplock bag & fill it with rice. It will suck out all the moisture. If you turned on after dropping it in water it might be to late.
Memo, here in the UK, the copper coinage stopped being pure copper ages ago... check it out with a magnet... seemingly, years ago, £1 worth of copper coins was worth more if melted down and sold as scrap copper, so newer coinage has other magnetic metal mixed in, to make it easier to catch out potential fraudsters.
amazing tip ma friend u are unique, l have a 70 200 with a big problem of fungs, would you recommend to expose for some time the lens before realizing your trip ? or it would be better to just skip the sun and go on the directiosn of this video ? thanks much blessings
You might burn the towel or catch it on fire, A hair dryer might be better. you want to get the copper hot, the towels just hold the pennies. Can you set it to 200 deg F like an oven?
can I do it with silver?, Coins are most common source of these material I suppose And we do not have any copper coin in our country :/ . Also I have a 50-250 mm . Do I need anything more to do than what's shown here?
1. So that the coins won't be scattered everywhere in the dryer. 2. Coins will be extremely hot. 3. Dryer's metal barrel will be badly scratched. It's all common sense...
Ok I am trying this on a lens I just bought second hand, I used the oven to warm the towels and have the lens+towels+coins in the bag will let them overnight, lets see what happens the fungus are just like small spots not the web like one ... fingers crossed otherwise I will have to return it :\
Ummm you do realize that this tip was too kill fungus, or as the video states, when your gear gets wet and you need to remove humidity that starts fungus growth. You say t didn’t work.....did you take the fungi’s vital signs before and after? My guess you didn’t, so how do you know it didn’t work? How would you? As for your infested lens, nothing other than physically removing the fungus from the lense elements will work....and sometimes the coating is compromised.
Failed to work!!! Tried 100 Hot Pennies. I was able to dry a wrist watch leaving it in a bag of rice but this penny trick didn't work. PROVE ME WRONG. I WILL SHIP MY LENSE TO YOU. IT'S A FAIRLY NEW 70-300 NIKON ZOOM. MINT COND EXCEPT FOR THE SPEC OF FUNGUS.
You want a dry box for the lens. Some copper can help with any fungus but a sealed box with descant is the preferred container. Do not use used decant... you need new or reactivate it as any moisture in the material will not absorb any more.
Quite serious. Because it would mean a difference between using new pennies vs older pennies that still have copper but at an amount that's significantly less than the old stuff. Chill.
what about if the lens has had fungus for awhile and you bought it without knowing the fungus was in it? can this still work or does it have to be right away when the moisture gets in
Hi guys. I tried this experiment on my dad's old yashica ML lens but it had no effect and changes. The mould or fungus is still there. I wish I could post pictures but my camera couldn't pick up the fungus in the lens... But I'm gonna repeat the experiment at a higher temperature.
Mars Aspen-Murray Oh, maybe I misheard something... but 2 weeks later, the fungus is still growing and I might consider sending to for it to be CLA'd. Sadly, it looks like I might have to throw it away...
Derp....this video has nothing to do with removing fungus. All this does is kill it. You still have to physically go in and remove it afterwards. Remake the video title and be straight up about what you're showing.
Well this is the first time I wish Canada didn't abolish pennies. Luckily I know some old coworkers at a metal processing factory so I can pick up old copper pipe pieces easily.
What the fck is happeniiinnngg!! Seriously, I´m such a big fan of you, can't really think of anybody having his shit that tight together. I've tried this specific trick for several times and...is not working. What I´m I missing? I even put the towel and the pennies on the oven before putting it into the bag, and the fungus still there. Any thoughts? Thanks a lot for everything you share with us!
fatbaldandhappy With all due respect, Juan Paredes is bloody right, he wasted his time and thanks to his comment I will not. The title of this video is in fact wrong - partly at least - and claims for something everyone wishes that is to remove fungus WITHOUT unscrewing the lens and by virtue of the regard for Ken knowledge, it is just natural to trust in what he's written and said and take for granted that fungus will disappear from the inside of the lens. It would be much better to entitle this video, "HOW TO REMOVE MOISTURE AND JUST KILL FUNGUS INSIDE YOUR LENS BUT IF YOU WOULD LIKE REMOVING FUNGUS WILL BE PROBABLY 100% NECESSARY UNSCREWING THE LENS AND IN THAT CASE TO UNSCREWING AND CLEANING IT WILL BE JUST THE BEST SOLUTION ONLY IF YOU KNOW WHAT YOU ARE DOING AND HOW TO DOING IT OTHERWISE JUST SEND IT TO REPAIR AND THAT'S ALL FOLKS!"
Anybody tried? I dont wanna break my landlord’s washer with those pennies lol. Why keep the lens cap on? Okay I will try this. Will it kill the fungi quickly? I have a 5mm size fungi in front lens.
