Zeiss makes a number of lenses in the Nikon F mount. In the past they have offered the 25mm F2.8 lens.

Over the past year or so they have been up-dating the lens line-up to include the CPU chip which supports all important operations such as the aperture settings and program modes.

They have just released the up-dated Distagon 25mm F2.8 ZF.2 lens. The cost is $1004. I should have them available next week.
