They are like the Panasonic 14mm lenses you get on ebay. Ex kit lenses. They explain it all in the listing.
"•These are lenses that were originally packaged with Sony Camera Kits. We sold the Sony Cameras in a quantity order, and we had simply removed the Lenses and placed them in their own box with all original foam packaging.These Lenses are limited quantity only."
