Easily the most valuable piece of camera equipment I've ever owned. 18mm for wide group shots or vast landscapes, 300mm (at 5.6G) for telephoto zoom wildlife shots. The autofocus is as fast as it was on Day 1 and it's a hard piece to replicate in any lens line up in terms of versatility when traveling and not having to swap lenses every time you're looking to grab a shot.
Bought new for $1000, selling for $675. Comes with lens protectors, a lens drawstring pouch, original user manual, and a polarized lens filter to reduce glare.
