Cloudy lens

I found a great deal on a used Olympus B-300 teleconverter. It arrived today, and although externally it looks great, it's extremely cloudy. I carefully cleaned the front and rear, but this did not make any difference. It seems that the cloudiness is on the inside. It looks a lot like the inside of my car's windshield :-(
I can't see any way to dismantle it, and I am not even sure if that's a great idea.
Do I now have a new paperweight, or is there something I can do to clean it up? I doubt that it would be worth spending the money to have it professionally done, but if I am wrong, please enlighten me.

Sounds like a good candidate for a return to me. Internal haze is never a good sign. And even in top shape these screw-on teleconverters (filters) do not yield very good results.

Hold it up to a lit light bulb. Fungus pasterns can be fascinating. Then toss that sucker and don't let it stay near your good lenses.

Yep. Appears to be fungus growing in. Worst enemy of a lens. The first DP Review on that teleconverter was February 2002. 16 years ago. Humidity, along with poor storage, is one cause of fungus beginning.

I wouldn't want to see what you'd call a bad deal!

Well, it did come from Florida. Humidity capitol of the world.
Paperweight it is then.

Return it and get your money back, the seller obviously failed to describe the condition of said item!

That's often the killer, but is the cost of the lens less than the shipping cost?

If you purchased it on ebay then the seller should have to pay the return shipping. It sounds like you purchased a lens with fungus/haze... unless it is really a valuable piece it is probably not worth fixing.... Your great deal maybe was just a little too good. I have fixed many older primes over the years that had similar problems, but have never worked on anything autofocus or zoom.
