• If this lens is used with cameras not compatible with vibration reduction, set the vibration reduction ON/OFF ring switch to OFF. With the Pronea 600i/6i camera, in particular, battery power may become quickly depleted if this switch is left ON. 3. Introduction En Thank you for purchasing the AF-S NIKKOR 500mm f/4G ED VR/AF-S NIKKOR 600mm f/4G ED VR lens. These are high performance lenses featuring special Vibration Reduction (VR) and high-speed Internal Focusing (IF) mechanisms. They also employ a Silent (S) Wave Motor to drive the focusing mechanism. Focus preset is also provided. ˾ Major features b Two AF modes (p. 27) Autofocus can be overridden by setting the focus mode switch to "A/M" or "M/A" and manually focusing with the focus ring. M/A: Autofocus can be overridden by manually focusing with the focus ring. This mode should be used for fine-focusing. A/M: Autofocus can be overridden by manually focusing with the focus ring, but focus ring detection sensitivity is lower than in M/A mode. Use this mode to avoid canceling the AF setting by unintentionally moving the focus ring. b Limiting the range of autofocus (p. 28) Focus time can be reduced by setting focusing limits. For example, if a subject is at least 8 m (26.2 ft.) (AF-S 500mm)/10 m (32.8 ft.) (AF-S 600mm) away, set the focusing limit switch to ∞ - 8 m (AF-S 500mm)/ ∞ - 10 m (AF-S 600mm). b AF-L/MEMORY RECALL/AF-ON (p. 28-29) Focus distances can be locked and saved during autofocus (AF-L) and then recalled by pushing the "MEMORY RECALL" button. Autofocus is restarted on the lens by setting switch to AF-ON. b Vibration reduction* (VR II) (p. 29-30) NORMAL: Reduces camera shake during handheld shooting or use of a monopod. This mode allows pictures to be taken at shutter speeds approx. 4 stops slower than is possible with a non-VR lens, therefore expanding the range of shutter speed options and making handheld or monopod telephoto shooting much easier. Panning is also possible. TRIPOD: Recommended mode to reduce camera shake when using a tripod. With a super-telephoto lens, camera shake may occur even when the camera is mounted on a tripod. TRIPOD mode reduces camera shake when shooting with a tripod, especially with shutter speeds between 1/15 and 1 sec. It also reduces image shake in the viewfinder. * Under Nikon measurement conditions. The effects of vibration reduction vary depending on individual and shooting conditions. 25
