I thought so too but saw them advertising a zone lens back in Feb. or March when there was a lot of talk about them on the list. Chris Patton's web site has been updated since I looked at it back then, http://www.stanford.edu/~cpatton/zp.html. He has added a PDF file that has 6 focal length zone plates ready for shooting which includes a 25mm plate. I've just started shooting with one and it works great.
