If this ebay link is working, can anybody tell me what an Ilex 12 3/4 inch medium angle lens is? Is this a lens for an 11x14 camera? Because 12 3/4 inch sounds about right for a normal lens on an 8x10. I am looking for a lens for my 8x10, and I have to scrape the bottom of the barrel with my budget, to achieve that. Why is this called a "medium wide angle lens"? Thank you.
