50mm lenses are fast lenses with a fast maximum aperture. The most basic 50mm lenses are typically F1. 8 - a very wide aperture. This means they are great for low-light photography (e.g. low-light portraiture or indoor shooting) as they allow more light into the camera's sensor.

For a magnification of one, 1.0, - the image size being the same as the object size - the lens has to be moved forward to twice the focal length. So a 50mm lens has to be cranked out to 100mm of lens to image distance. At 200mm focal length the distance is 400mm. That is almost 16 inches.
