There was some fungus or Haze in this nice old Canon FL 50mm 1:1.8, so I try to clean it away with some Hyrogenperoxid 3%.
But the some of the lens elements surface was too damaged so I couldn't remove all of it.
I can still use the lens, but there will be some loose of contrast...

I’m sorry the lenses couldn’t be fully cleaned, but the video was very informative. Thank you.

@peacekeepermoe 6 лет назад

Perhaps using vinegar or ammonia will get rid of the calcified fungal remains (inorganic remains)? Saw that on some other video, have never tried this myself ;)

@C2H5OHist 6 лет назад

Can't help but to marvel at something living in such harsh conditions and still accomplishing feats like etching through oxides and fluorides in the coating :)

@waynehearst317 2 года назад

mold and fungus is organic and alive. it literally penetrates through the lens coatings. I've had several Canon technicians tell me "sure, we can remove the mold and fungus....and all of the coatings on the lens", which would mean your lens is about as good as a cheap chinese knockoff from Amazon. Chromatic aberrations, lens flares and refraction would be horrible. The only way to approach this is to replace the lens elements, which usually will outcost replacing the entire lens. Especially on a 50 1.8 which retails for $150.

Use Pond's cold cream, the original that's been around for decades; not one of the varieties that's sold at Wal-Mart, et al. I had to get my jar of the original online. Buff it with clean fingers and the cream. You can apply as much pressure as you'd like whilst so doing. You can also use vinegar, and for the fungus, if present..

Thanks for these videos, I have the same lens and thanks to you and this video I opened up the lens and cleaned it to almost like new! Thank you!

@MikeVanRose 4 года назад

Very informative, thanks for sharing, what's the purpose of the lighter fluid?

@mikeno62 4 года назад

The Hydrogen Peroxide 3% is in my opinion one of the best fluid to remove Fungus, but I will also sooner try Vinegar just to see how it works. About the purpose of the lighter fluid, if there was any oil or grease, finger prints or something like that left on the lens surface, the lighter fluid will in most cases remove it. When I use different solvents, it's because lighter fluid is not an "universal" solvent for every job, sometimes I use Isopropylalcohol 99%, and in other cases it's Acetone (take good care) and again sometimes I also use dishwasher soap. Hope it makes sense.

@drumprof Месяц назад

I may have missed it, but did he mention that this lens is really quite radioactive?...and potentially dangerous to disassemble and work on.

@thesamuelputra 21 день назад

The element has thorium in it, but its embedded within the glass lattice structure. Not dangerous at all. You could put it under your pillow and sleep on it for 36 hours and have the same amount of radiation when flying in an airplane. To my knowledge the radiation isn't ionizing, so you should be alright. Thorium was popular before the 80s since it creates a really clear image, something to do with the refraction index of the lens.

hey mike i really need your help. have an AE1 but the depth of field preview is stuck in the engaged position, nomatter how i push the lever back over the red dot, it will spring back to the engaged position. ive checked that the lever on the side of the mount is disengaged and i dont know how to solve it😢

@trangphuongthao4340 2 года назад

Hi, thank you for amazing videos. I just wonder if isopropyl alcohol cleans as well as hydrogen peroxide. Did you tried vinegar for cleaning lens yet? Did it work?

@mikeno62 2 года назад

Well, the 2 chemicals are very different, the Hydrogen Peroxide 3% is very good to take away fungus or mold, but also good to wipe away if a lens element has some Haze. On the other hand, Isopropylalcohol 99% is very to cleaning lens elements if there is some oil or grease film on the lens surface, it can also be useful if there is some light Haze, but it all depence how much it is (that's just my own experience, during many, many lenses).

@fretlessfender 6 лет назад

If you look through a strong magnifier you might see that there is actually etching... regrinding the lens is the only option than... Might be interesting to know what kind of fungus it is and... how it gets there...

@DeusExAstra 6 лет назад

What would have caused the etching?

@DK-te4wy 6 лет назад

DeusExAstra Etching is the damage left by fungus after it's gone. Usually it's the eaten into the cement/balsam/coating etc. I'm not sure if it actually eats into the glass as well, but at the point there's a lot of fungus, there's not a lot of options.

@waynehearst317 2 года назад

It's actually easy to grow fungus on lenses. I've ruined a lens by simply carrying the lens cap in my pocket while walking around Disneyland all day, got home in the evening and capped the lens with a wet/moist lens cap and didn't use it for 6+ months. Boom. Fungus and ruined lens.

Any one familiar with a vivitar af 19-35mm? They where made onder several brand names like tokina, tamron and cosina. On my copy i have haze on the rear lens element. I have taken it out but cannot dissamble the glass from the steel case. It looks like it is a fix group glued together.

@Dutch3DMaster 5 лет назад

No experience with the lens in question, but it can look deceivingly much like that while it actually is not. I took a Orestor 135mm f2.8 (the Zebra striped version) apart to see where the haze was, and had the exact same feeling about the rear lens element. When I managed to get the ring off that keeps it in place, I suddenly had 3 seperate lenses in my hand, all well coated to stop reflections, which is why they can show up glued like that, I was astonished how well they were coated for a lens that old.

@therealchickentender 6 лет назад

You'd have a tough time contaminating your space enough to introduce a problem larger than the one being remedied here. May not be worth it for a few bits of fungus on the perimeter but when it gets bad like this, it's definitely worth a try.

@pxtokarev 5 лет назад

Fungus exist everywhere in nature. They are already there in every bit of glass or metal, but only grow in certain conditions of humidity and temperature.
