I came across an article in View Camera March/April 1996 that claims wide angle lenses should be focused using the "focus in" principle. That states that when t he subject is further away than the hyperfocal distance at the f-stop in use, th e camera should be focused at the hyperfocal distance, and carry the remaining d istance to the subject by depth of field for critical sharpness. For example, a 90mm lens on a 4x5 camera set at F32 has a hyperfocal distance of 17 ft., which is where the camera should focus on subjects that are further away than that. Th e depth of field at that setting would be 8.5 ft to inf. Is this correct?
