The lens captures the focus quickly and accurately and tracks it safely as the subject moves. The electromagnetic aperture control ensures precise and consistent exposure even at high frame rates. Nikon's silent wave motor enables extremely fast and quiet autofocus operation. Advanced AF tracking keeps moving subjects safely in focus even when motion is unpredictable or the subject moves quickly toward the camera. The electromagnetic aperture control ensures fast response and maximum precision. A focus range limit switch (FULL and ∞-5 m) makes it possible to further speed up focus acquisition, while focus functions taken from professional NIKKOR lenses offer outstanding adjustment possibilities. The focus modes (A/M and M/A) allow you to switch from autofocus to manual focus simply by turning the focus ring. The focusing ring can be easily and precisely adjusted thanks to the anti-slip structure. The focus lock function allows you to save a distance setting for repeated use. Perfect if you want to focus on the seat branch of a bird while hunting.
