An 18-200mm lens is a type of zoom lens commonly used in Photography. It offers a wide focal range from 18mm (wide-angle) to 200mm (telephoto), allowing for versatility in capturing different types of shots without needing to switch lenses. This makes it a popular choice for photographers who want a single, all-purpose lens for various shooting situations.
The pole of a lens is the midpoint of the lens' geometric axis. It is where the principal axis intersects the lens.
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
A 58mm lens refers to the diameter of the lens barrel at the front of the lens. This measurement is important for selecting compatible lens filters and accessories. It does not directly relate to the focal length or zoom capability of the lens.

The upper lens is called the ocular lens or the eyepiece.
It depends on the lens. Assuming parallel rays entering the lens: Convex lens - they converge, Concave lens - they dinverge.
