wonder if the nikon suit had something to do with this?
This doesn't sound like much use on more advanced crop cameras. By using non-cpu lens data setup you get aperture, exposure info, and more in the exif already. TTL Flash, distance to subject have little use on a fisheye. I suppose if they incorporate this into the 35 or 85 it would make a great deal of sense and we will likely see it in those soon.
