The optics of this lens on both my a 6000 and a6300 are just superb pin sharp ,colour rendition is what you would expect from zeiss this lens produces image quality that is equal to images taken using my a 7 ii with the sony zeiss 55mm 1.8 the build quality is also second to non the only downside is the noisy motor and its not as bad as the sony fe 50mm 1.8 lens which i also have as i only shoot stills i don't know how it would be on video sorry but for still photography this lens is well built light and produces brilliant images
Zeiss is renowned for high quality lenses/glass and this lens is no different. This is the BEST lens in this focal length area you can get for the nex/A series cameras.
Tax sharp, beautiful colour contrast and produces colour that pops. Once you try it you won't want anything less.
