The nursery rhyme Ring around the Rosie came about during the time of the Black Death. Here are what the lyrics mean: Ring around the rosie is a reference to the black sores that would appear on your body as part of the plague. Your rosie is around the center of the back of your hand. A pocket full of posies is a reference to people would carrying posies (flowers) around to not smell the sickening scent of dead bodies everywhere.
What is Vibration Reduction and how does it work? Camera shake (unintentional movement of a camera during an exposure) is probably the most common cause of pictures being spoilt by a lack of sharpness. Nikon's Vibration Reduction (VR) system helps to reduce the effects of camera shake. It is important to draw the distinction between subject movement and camera movement (camera shake).
The AF-P DX NIKKOR 18-55mm f/3.5-5.6G VR is also equipped with a vibration reduction (VR) mechanism offering camera shake compensation equivalent to a 4.0-stop* (with testing in accordance with CIPA standards) increase in shutter speed.
