As of recently I have been scowering Ebay for items that I’m looking to buy. I was looking for the Sigma 8mm Fisheye Lens  and suddenly I stumbled upon a used lens for sale. I have bought and sold a few lenses over the past couple of years and usually the only reason people would sell a lens is that they are looking for something else for thier pictures, and I always look into the seller ratings to determine the condition of the time and this it seems to be in excellent condition. And I saved about $250 for the Sigma 8mm lens instead of paying $679, which is the cheapest list price for new. Its always nice to get a good deal on an item off ebay.
