Hi Everybody
I have a mint condition zuiko 8mm fisheye lens that I've had for some time now. I got it very cheap as a package deal on an olympus om-1 camera. I'm not sure if I should sell it or not. I've been trying to figure out what it's worth but since it's such a rare lens I can only find one similar lens for sale on ebay with a fixed price of 2600 dollars and I doubt it's worth that much (or is it?)
I could of course just put it on ebay with a low starting price and see what will happen, but it would just be nice to know in advance more or less how much I can expect to get for it.

Thanks in advance.
