[. . . ] 14 LENS/TELECONVERTER COMPATIBILITY The following table lists a variety of Al-type Nikkor and Nikon Series E lenses which can be used with the Nikon AF Teleconverter TC-16. You can distinguish Al-S from Al lenses through the color of the minimum aperture indication on the aperture-direct-readout (ADR) scales—the Al-S's scale is engraved in orange, that of Al in white. It is impossible to attach the TC-16 to any prime lens on which another teleconverter has been mounted. If the prime lens is the 300mm f/2 IF-ED, make sure you don't use its dedicated teleconverter TC-14C at the same time. [. . . ] If the prime lens is the 135mm f/2, make sure you set the distance scale between infinity (») and 2m (6. 6 ft) in order to obtain precise in-focus indication. 6 ft), or the precise in-focus indication may not occur. To automatically focus on a subject from the maximum to the minimum shooting distance. sECONDARY PROCEDURES FOR AUTOFOCUS PHOTOGRAPHY As shown in the focus detection range chart (p. 17), the longer the focal length of the lens in use, the narrower its focus detection range. To shoot a subject that is in motion, you will need a wide autofocus operation range that covers the distance between you and the moving subject. If you set the prime lens's distance scale at infinity, the approaching subject may fall short of the minimum shooting distance for the focus detection range indicated. For example, when taking a picture of a subject with a TC-16-mounted 300mm f/2 lens within a range of 70m (229, 7 ft) to 10m (32. 8 ft), which is the prime lens's minimum focusing distance, you won't be able to shoot the subject if it comes closer than 35m (114. 5 ft) if you've set the distance scale to infinity because the minimum shooting distance required for autofocus detection to work at this distance is 35mm (114. It is thus best to reset the prime lens's distance scale by observing the following procedures. Detach the prime lens in use from the TC-16 and attach it to the F3AF/DX-1 assembly. Focus on the subject at its maximum shooting distance; then lock this reading on the prime lens's distance scale. (With the 300mm f/2 IF-ED, use the lens's convenient presettable focusing ring locking screw. Remove the lens in use from the F3AF camera body and insert the TC-16 between the prime lens and the F3AF/DX-1 assembly; then set the TC-16's ON/OFF switch to "ON". Focus on the subject at its minimum shooting distance. If both LED in-focus indicators (X) light up, this means the distance scale preset in Step 2 enables continuous autofocus operation, But if the LED focus-impossible warning indicator ( x ) * or the LED far-focus indicator (•*) lights up, this means the subject is closer than the preset minimum shooting distance. So, in this case, reset the distance scale by observing the following procedures. 18 (1) Turn the focusing ring of the prime lens clockwise (i. , while maintaining shooting position) until both LED in-focus indicators (••^i light up. (2) Confirm the position of the distance scale set in Step 2 and the position reset at Step (1). [. . . ] Observe the following tips, and the TC-16 will always work as perfectly as the day you bought it. €¢ Keep clean and protect the surface of the electrical contacts ® of the TC-16 from dust and dirt; otherwise, electrical malfunction may occur. 20 • Do not subject the TC-16 to shocks—especially avoid dropping or banging it on anything hard. €¢ If condensation forms on the TC-16 body, wipe it with a dry soft cloth.
