I have for sale a Schneider Apo Symmar 300mm f/5.6 lens in a Copal #3 shutter. Original Schneider lens caps are included. I bought this lens new and am the original and only owner. This lens has been lightly used and handled carefully, and is in excellent condition. There are absolutely no scratches or dings anywhere on either the glass or the body. In full disclosure, the front element of this lens has a case of "Schneideritis." You can Google the term for a little research. The effect is only around the outside perimeter of the front element, where the glass bonds to the lens body. This has absolutely no effect on the image. This can be seen in the 2nd and 4th photos below. But because of this, I will accept return within 10 days, no questions asked, with 100% of your money back, buyer pays return shipping charges. There are a couple of these on ebay right now with asking prices of $990 and $2295. I am asking $850.
