Got my new NEX lens, the NEX Zeiss 24/1.8. Technical specifications of the lens can be found here.
The thing that surprised me the most was the filter size was only 49mm. That's good news for me, I can use my existing filters that I used on my NEX 16mm lens and NEX 18-55 kit lens. This lens is not cheap because of the word 'Zeiss' but initial impression is that it's worth every penny. At f/1.8, it is sharp and the bokeh is creamy much like the Sony 135/1.8 (A-Mount).
Here are some sample shots of the NEX 24/1.8 on the NEX-5
