So in general the haze and fungus will give you roughly the same effect as having a "Pro mist" or any other diffusion filter on your lens. Funny enough for the price of some of these filters you could probably by a whole box of amazing hazy vintage beauties :)
Good video. Very informative. The fungus itself is not a big problem, as it can be easily removed. The main problem is the presence of fungus or (which happens most often) haze of the cemented lenses because of condensation or glue separation. You have to go through the complicated procedure of recementing the lenses, then gluing them again with either a special synthetic optical UV glue or Canadian balsam. In addition, you need to very accurately center the lenses. The slightest deviation from the center of the optical axis and the image will be poor. You have to go through the whole process again. And this is always a risk of damaging the lens, because in some cases you have to use heat. Since not everyone has special collimators for aligning the center of the lenses, this is a complicated procedure.
I have to say that personally I love the characteristics of the look with the fungus... It has a somewhat of an imperfect feel that makes it just feel right. Awesome video :)
Thanks for the video. I was able to guess every image right mainly due to the lack of contrast. Helps me decide wether or not to keep this lens I received with the edges slightly fungified.
I have to admit that I failed half of the comparisons. Im buying a lens that has some haze on it for real cheap, I hope it still produces good results. I asked the seller to show me some examples and the images look fine. And even if it doesnt produce decent results it will still be a nice collection item.
Very well done, thank you very much for the enlargements to be able to appreciate the effects of the fungus. Actually, it is not that serious, at least in the state that affects that lens, but, it is best to clean it to stop the damage. It's easy to get hold of the tools, disassemble and clean vintage prime lenses. You have to be neat and careful and have a minimum of skill with your hands. Thank you very much for uploading good content. Greetings from Buenos Aires, Argentina.
Great video, this is very important for people to see when trying to buy vintage lenses on ebay. fungus and Haze is not the end of the world, it will give you that promist effect so most people would love the lens without knowing it's actually the defects they like. But at the same time I would not pay top dollar for a vintage lens with these Characters. Seeing a lens with Fungus or Haze or Fog means it's not a clean lens and you shouldn't pay more for a dirty lens as you would a clean lens. But that's up to each individual interpretation if you care for these things or not. Also I would say 90% of Vintage lenses on ebay marked as MINT have these defects.
Great Video ! I picked all the Fungus images correctly against the Clean, which means a little haze does make a difference. I'll definitely be more careful when purchasing used lenses.
The lemon and the dead tree actually looked better, the rest, not so. Overall the bad photos make it undesirable to me. I would not waste precious shots hoping they turned out good. Great video, thanks for making it, I learned a lot!
I guessed wrong on two images. Loss of contrast its serious in some cases. Not necessarily a useless lens, especially since the center seems to be good.
@@FocalReduced i'm sorry. My comment was too unspecific. Uhm, i had noticed that the higher the f stop is, the more you can see the "impurities" in/on the lens. So i'm thinking that the presence of fungi might be more perceivable when shot at higher f stops. I could totally be wrong on this. I've only observed this on an old lens of mine with some dust in it but i no longer have it so i cant recheck.
Hi. I have a lens with much fungus. It’s not my fault, i bought it recently and I do care about my other lenses. Should I keep them apart? Any chance of contamination or is it safe?
Ah, the age old question of whether fungus will transfer over from one lens to another lens. Unfortunately, I don't know. Fungus grows from spores in the air. And they are everywhere. It is very likely that most lenses, already have some spores inside of them. They just need the right environment to grow. There are too many variables to correctly determine if they can migrate over to another lens. To be on the safe side, we would not put a fungus infested lens next to ones without it. The best way would be to clean it out, or kill it.
@@FocalReduced Thanks for your answer. As I understood this question has not got a 100% accurate answer. But I want to ask one more thing: If I mount my uninfected lens to a body which used with infected lens (or the exact opposite), is it risky or fungus nothing to do with the body?
It is difficult to assess. As long as the body isn't infected, there should be no issues. Keep all lenses and camera bodies in a dry location, perferebly a dry cabinet.
Thanks a lot for making this video! I've only fail to guess in the 4th image. Very interesnting information. I wonder if is possible to fix the contrast in Lr or other app?
Thanks for commenting. I believe with todays advanced software it is possible. However, I also believe that it might vary on the number of megapixels the photo was taken at. More megapixels might show more flaws created by the damaged lens..
@@FocalReduced Bit depth will always give you a better chance of recovery, more pixels, not so much.

So, even when you remove fungus with a clean job, there are still remnants? Does it mean that you can sometimes never totally remove the damage of a fungus?
i have three of this lens, all with hazy rear element, sold two of them and keep one, in case i miss the bubble bokeh, hope some day i can get the clean copy :D

I would certainly keep that lens! It has personality, signature, so nothing could go wrong for art photography.

Agree
Great point!
And if he keeps this lens with his other lenses eventually the fungus will spread to all of them giving them that "magic"
Thanks for the video. I was able to guess every image right mainly due to the lack of contrast. Helps me decide wether or not to keep this lens I received with the edges slightly fungified.
Great experiment, something that I was thinking about doing to find out about that issue. Fantastic. Thank you very much
Thanks for a really useful video.. The extent of the fungal damage, as shown at the end of the video, was quite surprising.
I have to admit that I failed half of the comparisons. Im buying a lens that has some haze on it for real cheap, I hope it still produces good results. I asked the seller to show me some examples and the images look fine. And even if it doesnt produce decent results it will still be a nice collection item.
Fuji should add a ProFungia film simulation to their list! Great video, thank you 😊👍
Yeah I just recently managed to get a copy of this lens specifically for the soapy bubble look. Few lenses will look this way.
Not a stupid lens experiment at all! A very important one. Thanks for doing it!

Virtually identical except for flare in direct sun. Very minor contrast loss is easily fixable in post.

Anywhere it was basically contrast between black and white, I could easily guess, but in the color photos, I couldn't tell.
Very surprising as some of the fungus images actually looked better...thanks 👍
Thanks 👍
Oh, great! Now the price of fungus laced lenses will triple! LOL! Thank you for a useful, real life comparison test.
Haha. We hope not.
I think it's interesting to see the differences when these lenses are shot at higher f stops.
Thanks for commenting. The more the lenses are stopped down, the less difference there will be in terms of image quality.

@@mylesdlm yes. In higher f stops the halation will be less but the foreign objects in the lens can create shadows on the image.
Thank you. Very helpful

Not all fungus and haze is removable. If fungus is left on the glass too long, it will etch the glass.
i have three of this lens, all with hazy rear element, sold two of them and keep one, in case i miss the bubble bokeh, hope some day i can get the clean copy :D
..the video, in the end, is before cleaning?
The lens has permanent damage from fungus and haze.
It seems like the contrast is the main issue. Not useless lenses tho.
Thanks!
Thank you
You are welcome.
You just can't spell fungus without fun.
Beyond sharp and resolution obtain with a fungus or not, at the end i, personally, do not want a glass with fungus! It annoys me in my soul!
Very understandable. Thanks for watching.
clean copy damage coat?
