Louis,

Dan's idea is a good one. I own a Wista Field with only 12" of extension and the Nikkor M 300mm. I fashioned my own extension lens board out of masonite, a few reinforcing pieces and screws. It sets the lens about 2 1/2" farther forward which allows focusing to about 10 feet (if I remember correctly. Since I use this lens mostly with distant subjects, this works out well. The only drawback is the limited front tilt/swing due to vignetting, but I can live with that. Hope this helps. ;^D)
