Zeiss really did a great job producing this 12mm f/2.8 auto-focus lens for Sony E-mount. Similar to a 18mm wide angle lens on a full frame camera, the 18mm has that crisp and contrasty Zeiss "look". All metal and rubber design looks and performs great. Fast autofocusing and bright f/2.8 aperture makes for great landscapes and interior shots. Reasonably close focusing allows for neat perspectives. For crop sensor Sony cameras like the a6000 or NEX-7.
