Explanation of Nikon 70~200mmf2.8 first generation lens unlock key

There are several keys on the mirror body, starting with the golden signboard, and the introduction begins with the first one.

1, A/M and M/A modes: By rotating the lens focus ring, M/A can make the focal length better than autofocus, and A/M must continue to rotate the focus ring to make manual focus take precedence over autofocus, so as to prevent unintentional operation of the focus ring from causing unexpected changes in focus. In addition, the same as above.

2. Focus limit switch: This switch determines the focus limit value of autofocus. Full: Select this option to use the full focus range, that is, 5 meters at infinity. If the subject is always at least 5 meters away, please select this option for faster focusing.

3. Damping (VR) can reduce the blur caused by camera vibration and reduce the shutter speed by 4.0.

Select Off to turn off damping. When shooting, select "Normal" to increase the shock absorption effect, press the shutter release button halfway, and the shock absorption will take effect. Select sports to shoot athletes and other objects with quick and unpredictable actions, and press the shutter release button halfway, and the shock absorption will take effect.

4. The lens cover can only protect and block the scattered light that may cause stray light or ghost.

Evaluation of Nikon 70-200mmf2.8 Photography Authority

Nikon AF-S Nick 70-200mm2.8g and VR II were released in July 2009. It is an updated version of its predecessor Nikon AF-SNICK 70-200mm2.8g EDVR.. The latest image stabilization technology with a new optical layout is called vrii, which can provide up to four image stabilizers and shoot clear images at a low shutter speed.

This is very important for telephoto lenses, because at a magnification of 200 mm, without VR II, you need a fast shutter speed (not always possible in dim light) or a very stable hand.
