Lens Basics

The camera is basically a light-tight box that captures the light; it is the lens that focuses that light to create an image on the digital sensor. Modern camera lenses are made up of multiple glass (or plastic) lenses, all positioned to focus the light traveling through them onto the sensor. There are a great many lenses available for the Nikon D3200 and the choices can be confusing. Once you have a better understanding of the differences among lenses and why some cost so much more than others, it will be much easier to choose the best lenses for your shooting needs.

Lenses are classified by their focal lengths, and their widest aperture or aperture range. There is also Vibration Reduction (VR) technology built in to some Nikon lenses that allows for sharper photos at slower shutter speeds.
