Recently purchased the new 16-35 f/2.8L III, and therefore no longer need the f/4 "little brother". This is a fantastic lens, razor sharp all over the place, great colors too. Rock solid IS, and a nice lightweight body that makes it great for travel.
I purchased this lens brand new back in 2014, and it has been very well taken care of. Never been dropped! Comes from a smoke-free home. Been kept in padded backpack when not in use. I also had the B&W XS-Pro filter on this lens its entire life, so the front element is perfect (along with the internals, since the filter completes the weather sealing).
Also included is the aforementioned clear B&W Nano XS-Pro filter. Perfect shape. This is the low-profile filter that you want to use on UWA lenses in order to prevent vignetting.
Body Condition: 9.5/10. No blemishes.
Glass Condition: 9.5/10. No blemishes.
Comes with: everything you get with the lens when purchasing new, to include the original box.
My feedback: 100% on eBay, and all positive transactions here on POTN (check the Feedback thread).
Price: $750, shipped from Maryland. International buyers may be required to cover any additional shipping/customs costs.
(Photobucket is down right now, so can only upload two at the moment). I have a few more photos, just ask if you want to see them!
