this probably belongs in the rumour forum due to the fact that it hasn't materialised in the marketplace just yet. But here is a look at the new Pentax D-FA 645 25mm f/4 [IF] SDM:
To my eyes it looks like a well designed pre-production mock up lens...but considering they have gone through all this effort I am sure it won't be much longer before this lens appears on the market. It will be the widest medium format digital lens wider than any lens from Phase one, Mamiya or Hasselblad which all have 28mm lenses as their widest focal lengths.
there is an article on it on PhotoRumors, if you haven't already gathered that from the pic I used.
