See my post #34. Thanks to the internet attitude of "I read it on the web" all odd things have become fungus.

Go rent a gun and blow my brains out?

You would need to buy one as you wouldn't be able to take it back if you rented it!

I guess the lens cement isn't all it's cracked up to be.

I have not seen a snowflake pattern, but have seen a filamentous web-like appearance, and a fern-like appearance.

This one, if it was not symetrical would look fern-like. In fact the second smaller one does look like a fern. The weblike fungus is, I think, the same thing just expanded to the point where it is crisscrossing over itself repeatedly. I have had lens with both types of patterns in them, the web looking one was about 90% covered. They are quite attractive, if you don not have hundreds of dollars invested in the darn fungus. The one that was so bad was given to me, a 50mm f/1.4 Fujinon, so I could enjoy looking at it, it had spread to the point where it was on the shutter of the camera as well. On the surface of something they have a kind of white waxy look to them. When they are very small they just look like a white blotch with no noticeable pattern.

There are probably other fungi that have a different look to them. In fact here is the dictionary definition:

fungus

fungus (fùng´ges) noun
plural fungi (fùn´jì, fùng´gì) or funguses
Any of numerous eukaryotic organisms of the kingdom Fungi, which lack chlorophyll and vascular tissue and range in form from a single cell to a body mass of branched filamentous hyphae that often produce specialized fruiting bodies. The kingdom includes the yeasts, molds, smuts, and mushrooms.

[Latin; perhaps akin to Greek spongos, sphongos, sponge.]

Dear Graywolf,
the lens is yours, and you can believe what you like.
If i where in your shoes, i'd disassemble the back cell straight away, and find the answer.
If it's "inside", it's NOT fungus.
Of course i'd hope with all my heart that's some fungus, cause it's perfectly cleanable most of the times.

As you haven't done it already, i guess that you won't open the lens in the near future...
In this case, i would buy a 150mm Componon-S off Ebay, and mount the cells in your shutter.
If you're not in a hurry, you can get a good one for as low as 50 bucks or so.
Then you have a lens with the appropriate diaphragm scale, and with an image quality only marginally inferior to a modern Apo (heavens forbid, what am i writing!)


cheers

It's been fun, guy.

Or not.

Well, I will open the lens cell, soon. Got other projects to hand at that moment. I certainly was not going to open it until I had firmly decided for sure I was not going to send it back. I have had spanners slip too many times to take that kind of chance.

Now if I could just learn to spell "beautiful".
