Sony NEX with Zeiss Super Speed 16mm f/1.2 Arri Bayonet Mount Lens
Here is an interesting lens we ran into on eBay. It is a Carl Zeiss 16mm f/1.2 lens made for the Arriflex Super 16mm cameras. Breguet Camera of Hong Kong is offering this lens and has modified it for the NEX E-mount. This Super 16 lens will not cover the NEX-5's APS-C sensor and will cause vignetting as seen in the sample pictures below. This may not be a problem if you crop the image or use it for videos. This lens will work with NEX cameras via an Arri to PL to E-mount lens adapter which is included with the auction.
Here is more information on the Carl Zeiss Super 16mm MKI lens from cinematechnic.com:
Super 16mm Mk. I Set
The 16mm set comprised of four Distagons: 9.5, 12, 16 and 25mm, f1.2, all with a photometric aperture of T1.3. These were the first 16mm prime lenses designed to cover Super 16mm format. The 9.5mm focal length covers the full S16 aperture, but is somewhat compromised in sharpness and illumination past the corners of N16. For this reason ARRI did not include the 9.5mm on their list of S16 compatible lenses. All the S16mm Mk.1 lenses were fitted with 6-blade hexagonal iris.
