Serial 47612789. Bought specifically July 26 for a trip to the Okavango. I no longer have a need for it. Front glass was covered with Haze filter from day one. Paid $575 including Haze filter, Tiffen Polarizer and Opteka shade. I stupidly forgot the polarizer at home so it's never been used. Asking $480 firm incl. free shipping within US. Paypal only. I'm not providing photos of the lens here as it's in LN condition. Comes will box, manual, and paperwork (not yet registered). I can provide Jpegs of photos taken with it. 100% eBay positive feedback.
