I recently bought a lens from ebay and found this on the inside of the front element -
Was it caused by a fungus infection? I can have the lens returned for a full refund but I would like to avoid the hassle if possible. It doesn't seem to be affecting image quality yet. Does anyone know if it can be cleaned professionally? If so, what will be the approx cost?
Since it runs along the edge, it is more likely early element seperation - but it could also just be some grime/oil along the edge of the element. Hard to say without more detailed pictures.
I have added a link to a close up. They normally don't show up unless you look at it at a certain angle. I really hope it is not fungus so I don't have to go through this return, refund headache.
The new photo is more confusing. Even if it's a headache, you don't want to be second guessing yourself. I'd return it. Fungus etches the glass...
Your close up shows piles of stuff.
