Purchased unit with Metabones speed booster Sony A - E mount with 77mm B&W UV filter. Mounted once on Sony A7r to test mount. Put it back in box. Two week later we switched to Cine lenses (Canon & Angenieux zooms). It is literally brand new. Other than the trial mount, it's never been out of the box. Perfect for photography and video, crystal clear focus, fast 2.8. If you're shooting and not planning to put it on a big screen in a theater, it's a gem. Total package new now is $1515-$1645 depending on where you buy it.
