I am considering trading my Zone VI 4x5 Field Camera for a Wisner Expedition or Pocket Expedition. The Zone VI is too heavy and I find thee front standard to b e a bit flimsy. Has anyone had experience with the Wisener Exp. or especially th e newer Pocket Expedition? I especially like the geared rise/fall. Will the smal l size of the Pocket be problemmatic in the wind? I appreciate your comments.
