Excerpt: This was given to me by a client as a gift - I love it. Put it through countless jobs and it excels and impresses me everytime. Feels like cake in your hands and shoots like rainbows. nice glass for the money.
Pros: Durable, Fast / accurate auto-focus, Rugged, Strong Construction
Summary: My favorite lens for my Nex 7s, very sharp, great color, everything a Zeiss-inspired lens should be. Great focal length for walking around, especially with a 24mp sensor that allows hefty cropping when necessary. No stabilization, though--they probably figured at this length it isn't that workable anyway, though others have stabilized this length and wider.
Summary: There are very high expectations when you buy a Zeiss lens. The name/brand is a bit legendary in the photo industry. It's "the good stuff",the "top of the heap"... This particular lens is built in Japan (OK by Me!), not Germany...None the less it wears the blue "Zeiss" badge on it's side...
Summary: Pros: The resolution is noticeably better than the kit lens of my NEX 7. The difference is greatest under low light conditions. You can use faster shutter speeds for moving subjects. Suitable for indoor photos.
Summary: Great sharpness and contrast at f/4-f/8. Center sharpness wide open is nothing to laugh at either. As good as it gets for the Sony APS-C E mount. My favorite lens along with the Zeiss Touit 32mm.
