Summary: This is one of my favorite lenses, hands down. I am a professional wedding and portrait photographer, and I use this more than 50% of the time. The Zeiss opticals truly set this lens apart, and at 1.4, it is just stunning. The motor is very quiet and smooth, and the 50 1.4 focuses extremely quickly.
Amazing lens. I own every Sony Zeiss full frame ...

Summary: Amazing lens. I own every Sony Zeiss full frame lens an I can tell you that this is not just technically good, sharp from corner to corner as a Plannar design should be but it has a lot of character, creates beautiful images, really addicted to it.
Summary: For a technical review read Kurt Munger's in depth analysis. As for real life analysis it's simply fantastic. I've been an avid shooter of the 50mm 1.4 Sony for over two years. This has all the magic I've come to love in my 135mm 1.8 Zeiss.
Excerpt: I wasn't sure whether to retire my Alpha 900 and move on, or to add a second ZA to my system. I've been using the ZA 135/1,8 for 2-years now without ever removing it, so I have done just about everything one could do with that lens.
Summary: UPDATE: 17 April 2014 After two months of using this lens in Europe I'm very impressed with the results. The renderings and colors are so 'real' and life-like that's easy to see why this lens cost more than other options.
Summary: I can't say enough about this lens. It's a perfect 50mm. It's very sharp at 1.4, and by f/2, where I almost always leave it, it's perfect. Great balance on the A99, great hood. I sold all of my Canon gear to shoot with this lens and the A99, and it's been amazing.
Excerpt: Very sharp. Great colors/contrast. The only thing I would have done different to this lens is put the focus hold button on the other side of the lens like the 85mm Zeiss is. It makes it difficult to use the hold button on the side they put it on.
