"There is some interior haze"?

[yalcinaydin]

"The glass is clean and clear with no scratches, fungus or haze. There is some interior haze."
Is this a problem? I haven't seen a haze before What is the effect of it?

[Sevo]

I tend to translate ebay descriptions like that as "I cleaned the dirt off the outside with some toilet paper, but the inner surfaces are a mess".

You sometimes find lenses that have some internal elements which are neither scratched nor infected by fungus but still are not as transparent as a clean glass. There seems to be some kind of veil, some light fog on these elements. This "haze" can be caused by tiny drops of humidity due to internal condensation or by fumes of glue that has been used or by another reason.

Sometimes this haze does not have any considerable effect (like with my Nikkor-Q.C 3.5/135), sometimes it lowers contrast and impairs effective lens speed (like with my Spiratone).

In many cases this haze is not getting worse. I just had my (hazy) Nikkor-Q.C 3.5/135 checked by a pro and he told me not to worry and to do nothing but using this lens.

if center part covered with haze fully result will be very contrast less. Some haze is not a problem.

Long time ago.... girlfriend (not anymore ) left new zoomlens for my rikoh kr super on the car dashboard for 5 hours in the sun
when i removed it from the dashboard i couldnt touch it from the temperature and had to use a cloth
The next day on the camera it was totally hazed up i could not even see anything but white haze

i think the grease in the alluminium outside parts of the lens housing boiled off in the heat and then condensed on the slightly cooler glas parts of the lens....evenyually got new one....no not zoom ...girlfriend

Hmm, it is a big risk for a min 200usd lens so I will look for a clean one.

But perhaps haze is cleanable. Scratch is not repairable (unless you replace the glass).

This is an interesting topic, and one that begs to be asked by a newbie:

What is the haze from, usually?

Is it something on the outer surfaces of the glass, or is it typically
a heat or chemical reaction to the cement used to bond glass elements
together?

I ask this because I would like to open up lenses for cleaning,
if I should find really great bargains on lenses that need some attention.

"A fast one... so don't let it get away. WOW F2.8 straight through this zoom lens. The glass is clean and clear with no scratches, fungus or haze. There is some interior haze. Includes the hood and a Nikon AI-S adapter, but you can use any one you have for your body. In the case."

This rating system and description is really confusing. They say that they can send to APO address so it was a chance of avoiding customs Now, I will wait for another hooded Tamron SP 80-200/2.8.

That's a very good repair, isn't it??!!!!

Twenty years ago - or so - I had a tele tessar 4/135 for Rollei with haze internal between the first and the second elements.

I cleaned it in several times, but the haze became again and again.

I didn't know (nor now) why it ocurred.

The repairman told me that don't matter to me, "use the lens" - he said

I sold it WITH HAZE.

The haze isn't a good experience to me. Never will buy a lens with haze again

I don't know. But I will not repeat the experience.

The quality and performance of a camera lens or any other type is proportionate to the quality of the lenses used in its construction. Lenses by definition are clear, their job is to transmit light (making an image) in the most efficient way that can be devised.
I have never seen a hazy lens that can produce good results, ANY type of haze on a lens will degrade the performance.
Whether the proportion of degradation is acceptable to you is a different question. The question of it being remedied is always a risk unless it is a very simple lens.
The bottom lime is unless the lens is dirt cheap or only wanted for show or to play with give it a wide berth.
Never buy a lens without shining a bright light through it (A small torch) if it isn’t clear don’t expect clear pictures.

Haze is worst case in lens problems as Rob said it impact picture quality at covered parts. Some of them cleanable , because just dust some of them un-cleanable with simple methods. I buy lenses with haze if lens is rare and I can't take other one. I also buy lenses with haze if cover the edges only, because on my 2x crop DSLR not impact anything.

[LucisPictor]

This might be generally true, but as I said, I get great results from my Nikkor 3.5/135 that has some haze inside.
And a pro told me not to bother, because any attempt to repair could make it worse than having slight haze if not done professionally.
It will lower contrast a little, yes, but that's all. This is what he said and what I can confirm from my experiences.

I received a Pentax M 50/1,7 on a trade today...it seems like it might have haze near the front

There are what look like very small speckles covering the whole element. I could not see this until I started looking for internal issues. Tomorrow, I'll try to get a pic OF the lens and WITH the lens...

If I need to sell my lenses I also keep with fungus and scratches, because most of them not impact anything and re-sell value is low.
