RE: Large Lens On Ebay

The listing on ebay says that this lens has a 48" focal length, and is f/6.3. So the clear diameter of this lens is 48"/6.3 which is 7.62" diameter or 193.5mm. That is a lot of glass for the money, but it would probably be hard to figure out which type of glass each element was made from if you wanted to use the glass to make a color corrected design. Good luck and happy biding. Steve
