"Several of the currently offered manual focus Zeiss Z-series lenses are based on fairly old designs. However, slowly but steadily we are seeing newly developed lenses like the Distagon T* 35mm f/1.4 and the Distagon T* 25mm f/2. This time we'll have a look at the latter one. The T* 25mm f/2 is available in Nikon F and Canon EF mount. Apart from the lack of AF it is a fully coupled lens so a camera-controlled aperture, focus confirmation and EXIF data is supported. The Distagon is, obvious, a moderate ultra-wide angle lens with typical applications such as landscape, street and architecture photography. It is, of course, not exactly a budget item but it isn't any more expensive than its nearest competitor - the Canon EF 24mm f/1.4 USM L ... which has the advantage of being faster though. The optical design is not identical to the Zeiss ZA 24mm f/2 SSM (for Sony Alpha), BTW."
