I am blessed with 3 of Mr. Pinkham's lenses.  2 Series IV and a single 9" Series V Synthetic.  I have not done the Synthetic justice before now.  Last weekend I got to do 2 shots with it.  A case of being perfectly happy doing something else, seeing light interacting with a possible subject, and acting on that by setting up the equipment to get the shot.  This is on 8X10 with a good long bellows extension.  Wide open, I calculated and equivalent f9.  This has whetted my appetite for this lens, it is simply marvelous!
