1-53. What  distance  is  required  between the lens and the focal plane so the image formed by a 2-inch focal- length lens is the same size as the subject? 1. 1 inch 2. 2 inches 3. 1.4 inches 4. 4 inches 1-54. The distance the focal plane can be moved  forward  or  backward  from  the plane of sharp focus and still record an acceptably sharp image is known by what term? 1. Depth of field 2. Circle  of  confusion 3. Depth of focus 4. Hyperfocal  distance 1-55. What  term  describes  the  distance from the lens beyond which all objects  are  rendered  in  acceptably sharp focus when the lens is set at infinity? 1. Hyperfocal  distance 2. Depth of field 3. Depth of focus 4. Near distance 1-56. What  is  the  hyperfocal  distance  of a 6-inch lens set at f/11 when the permissible  circle  of  confusion  is 0.006  inches? 1. 2.38   feet 2. 36.72   feet 3. 545.45   feet 4. 3361.11   feet 1-57. Your lens is set at f/11, the hyperfocal distance is 71 feet, and your subject is 112 feet from the  camera. You should focus at what  distance  for  maximum  depth of field? 1-58. Of the following lenses, which one provides the greatest depth of field when set at f/5.6 and focused on an object 6 feet from the lens? 1. 35mm 2. 50mm 3. 80mm 4. 135mm 1-59. Which  of  the  following  factors affects  depth  of  field? 1. Lens focal length 2. Lens f/stop 3. Camera-to-subject   distance 4. All of the above 1-60. You are using a lens focused on  the  hyperfocal  distance  which is 50 feet. What is the approx- imate  depth-of-field  range? 1. 25   feet   to   75 feet   only 2. 25   feet   to   infinity 3. 50   feet   to   infinity   only 4. 75   feet   to   infinity   only 1-61. What is the depth of field of a 50mm lens set at f/8 with a permissible  circle  of  confusion  of 0.002 inches when it is focused on an object 20 feet from the lens? 1. 10.0    feet   to   20.0    feet 2. 15.7   feet   to   23.4   feet 3. 18.6    feet   to   21.7    feet   only 4. 20.0    feet   to   23.8    feet   only Learning Objective: Determine the relationship between the subject/image size. 1-62. A document is 1-inch square. You must photograph it to produce a 4-inch-square image on the film. Using a 6-inch lens, what image focal  distance  is  required? 1. 35.5   feet 2. 56.0   feet 3. 71.0   feet 4. 112.0   feet 1. 10   inches 2. 12   inches 3. 24   inches 4. 30   inches 6
