I am interested in obtaining a handheld 4x5. Am I restricted to the press camer as of old or is there something that I can buy new that will fit my needs? Is t here a ragefinder situation that I can fit on to my existing view camera? Is th ere a conversion kit made that I can affix to my feild camera? I am looking for 4X5 candids. Any help would be greatly apreaciated. D. Austin
