I`m looking for a 4x5lens that can give me the most depth of field in "Makro" si tuations. At the same time I need a great shapness quality so I can make large p rints (55x55inches). For example these "Makro" situations have the following dim entions: 35-55cm wide by 30-50cm deep. The depth range that I`ve just mentionned is the minimum D.O.F needed. The height might vary from 15 to 40cm. Hope this i sn`t too confusing.
