Is this lens fungus?

baachitraka · Feb 3, 2016

For my eyes they look fine but I am doubtful about the green edges.

AgX · Feb 3, 2016

I say yes. At least it has this typical dendrite structure.

But what I see from that photos would hardly effect the image as I do not see whole areas affected, just those tiny dendrites and then in the viewing lens.
But assessinng from a photograph is hard. I'd rather have a lens in my hand to examine by view.

I see what looks like a piece of dust in the second picture... and not sure what other potential issues you folks are seeing

cramej · Feb 3, 2016

I see dust.

480sparky · Feb 3, 2016

I see dust and hair/fiber. How about an arrow in the pix pointing to the suspect?

AgX · Feb 3, 2016

Have a look at the viewing lens at largest magnification.

Kirks518 · Feb 3, 2016

No. i see no fungus in any of the photos, on either the viewing or taking lenses.

As far as the 'green edges', that's the glass.

R.Gould · Feb 3, 2016

I can't see any fungus, some dust,some hair and fibres, perhaps some scratching due to over zealous clesaning perhaps on the viewing lens, but no fungus and nothing to affect the taking of photos

I'd have an extra look ... since it is a Planar 2.8; they seem to develop balsam separation, which at least according to the repair-man I consult is hard to do anything about and with a great of risk of ruining the lens.

If you are a potential buyer, ask for a guarantee that you can return it or have a hands-on look at it.

Cleaning scratches look different, than dendrite marks from fungus.

choiliefan · Feb 3, 2016

The last pic of the viewing lens does show what appears to be tendrils of fungus. Lacking a better pic, it could be lightly scratched coating on or near the rear element, I guess.

RobC · Feb 3, 2016

I only see dust and cleaning marks. Possibly a scratch on the inner surface of the one with the blades behind it. If it is fungus it will casue no problem from what I can see.

I think the green edges are cleaning marks.

The fungus I had on one lens was white and looked completely different from the dust I can see on your lenses. Fungus has tendrils more like fern leaves or fine branches.

I see people hallucinating, the OP most of all.

Sit it in direct sunlight for a day or two or put it under a UV lamp for 8 to 12 hours. Check it again in 3 to 6 months to see if the suspected area has increased or not, most likely it won't. The green along one edge is possible corrosion of the brass mounting or a sealant, can't tell without disassembly, nothing to be concerned about. The only other possible edge defect may be the early stage of fungus, edge separation of a cemented pair, or the edge paint of a cell or barrel flaked off. Look at it with a high power loupe, if it looks like tree limbs or snow flakes its fungus, treat as described in the first two sentences of this post, otherwise don't worry about it.

If there's any brass in the construction of the lens mount then the green around the edges could be corrosion.

Greg Heath · Feb 3, 2016

Fungus amongus....nope..

it's definitely not fungus. I would agree with the guy below here that it is corrosion on the brass. I saw some on a Pentax 1000 I had apart yesterday. Lens fungus is white and grows and pits the lens. Your lens looks nice. I have taken fungus off lenses before without pitting. You have to soak the lens after your disassemble it in a 50/50 solution of Hydrogen Peroxide and Ammonia. The only lenses I wouldn't soak are lenses that are cemented together. As for your lens, I wouldn't touch it...it's looks fine.

That was Rolleiflex 2.8D was gone for €399 on Yesterday. I asked the seller again which I presume do not know much about the camera and he told there is a fungus in it.

I did not buy it.

Given the age of the camera, I reckon it saw them too.

Greg Heath · Feb 4, 2016

Ask him for a price discount or a refund time period. That lens looked pretty clear to me. Removing the lens is not difficult. It unscrews if its anything like the Rolleicord i CLA'd.
Fungus does not freak me out. All but the worst fungus can be removed.

RobC · Feb 4, 2016

it was sold to someone else

StephenT · Feb 10, 2016

I don't think it's fungus.

Is this lens fungus?
