I'm selling my used but like new Canon 8-15 f4 L USM Fisheye Zoom for $1250. The lens is in excellent condition with no scratches/marks/smudges to the glass (front and rear elements) or the barrel.
The AF/MF switch and the focus limit switch both work perfectly and the Autofocus and image quality are excellent.
There is no date code as Canon stopped putting them on newer lenses but I purchased this new from Amazon in August of 2012 and can provide the receipt if needed.
Includes everything the lens came with (box, packaging, warranty card, manual, hood, cap, lens pouch).
Currently Selling for $1,499 on Amazon, I'm selling for $1250 OBO, cash and would prefer local pickup but I can get a quote for shipping if you're interested.
