I just got this lens. (01/30/2012)reviewed January 31st, 2012 (purchased for $1,800)
It's an unbelievable piece of glass. The Zeiss coating is just different than others. I can't explain what it is but this lens renders images beautifully. Contrast, colors, sharpness etc. etc. are all top notch. I simply love this lens despite the fact it's a manual focus lens. Zeiss website shows movies on how to deal with that (if you're not familiar with manual focusing) and how/where to get focusing screens for your camera.
The lens is all metal (including the hood) so it's heavy but the images it produces make you fly so don't worry about its weight.
Sample images (panoramas) are on my website http://www.eveningphotography.com
Search for images from Joshua Tree Park, they are all taken with Zeiss 35mm f/1.4 lens.
