I just received this information from Zeiss.
The have a new 28mm F2 lens in the Nikon F and Pentax K mounts.
The price for either lens is $984
We're now taking orders.

The Zeiss Distagon T* 2/28 is a new, high-speed, wide-angle
lens, complementing the line of advanced SLR lenses from Carl
Zeiss for analog and digital 35 mm single lens reflex cameras.
With a fast aperture of f/2 and a 28mm focal length, the
Distagon T* 2/28 is the ideal bridge between the existing wide-
angle lenses with 25mm and 35mm focal lengths.

The new lens is available in two versions: Distagon T* 2/28 ZF
for cameras with the F-bayonet mount and the Distagon T* 2/28
ZK for cameras using a K-bayonet mount. It is one of the fastest
lenses available in this focal length and is ideally suited for tak-
ing photographs in unfavorable lighting conditions. Equipped
with manual focus, a high quality metal casing and floating ele-
ments, it provides demanding photographers with a creative,
top-class tool with lasting value. The performance of the lens is
consistent throughout the entire image field, even with profes-
sional digital cameras featuring full format sensors.

Lenses with a 28mm focal length are popular for landscape and architectural photography and the Distagon T* 2/28 ZF is
ideal even for high quality, close-range portraits. Due to the high speed of the lens, it is particularly suited for taking pictures
indoors under natural light or other low light conditions.

The Zeiss Distagon T* 2/28 uses floating elements, ensuring impressive image quality in both the close-up range as well as at
longer distances. With a fast aperture of f/2, photographers enjoy greater creativity through flexible use of the depth-of-field.
This enables them to effectively separate the subject from the background at full aperture and achieve a strong 3D effect. High
image quality is provided under all conditions, from wide open to stopped down and at different focus ranges, despite the ex-
tremely high speed.

With its numerous, outstanding properties, the Distagon T* 2/28 from Carl Zeiss is a versatile, multi-purpose lens for the de-
manding commercial, landscape and fine-art photographer. Thanks to the standard F and K bayonet mount connections, the
lens can be integrated into the corresponding camera systems with some limited compatibility on a case-by-case basis with
the simpler camera models.
