For shooting subjects which are located closer than the closest possible focusing distance of the lens, Nikon offers a wide variety of close up equipment as shown below.
In close up photography, depth of field is usually quite shallow. Thus, you should stop the lens down as much as possible when photographing a subject having great depth
To focus in close-up photography, use the matte portion of the screen. Or replace the standard Type K2 focusing screen with the Type B2 or E2 screen. (For details about interchangeable focusing screens, refer to page 66.)
To measure the exact distance between the subject and film plane, use the film plane indicator ^~r which indicates the exact position of the film plane inside the camera. The distance between the film plane and the lens mounting flange is exactly 46.5 mm.
Close-Up Equipment
•Close-Up Attachment Lenses Nos. 0, 1, 2, 3T, 4T, 5T, 6T. These lenses screw into the front of the lens just like filters to magnify the image Exposure metering can still be done at full aperture without compensation.
•Auto Extension Rings PK-11, PK-12, PK-13. These fit between the lens and camera body. Used singly or in combination, exposure determination is done at full aperture with all Al-type lenses.
•Bellows Attachment PB-6. The PB-6 is also attached between the lens and camera body. Exposure is determined by the stop-down method with centerweighted metering. The beauty of this accessory is that you can change magnifications continuously by extending the bellows.
•Micro-Nikkor 55mm f/2.8, 105mm f/2.8, 200mm f/4 IF lenses. These specially designed lenses for close-up photography offer continuous focusing from infinity down to 1/2X lifesize.
