Glass by the pound
Found an unidentified large lens on eBay for about $9 per pound. The glass appears flawless and it seems to have a focal length of around 12″ and an exit diameter of about 3.5″ making it in the neighborhood of f 3.4 crudely calculated. Might work for 8×10 based its apparent coverage circle (once I make a brawny enough camera to carry it – it weighs 7.5 pounds)). That is a far future project however as I am still refining my ability to do 35mm and sixth plate.
