Many cameras are built to take special additional lenses that screw or snap on. If yours doesn’t, don’t worry; the lens it was made with will be a generic type that will do most jobs reasonably well. If you want to get into using extra lenses, there are several different types.
A wide-angle lens can be a useful addition to your camera, especially for landscape shots. It can reach out to each side and gather in lots more than your normal lens and indeed, even more than the human eye can see. It will be able to focus on foreground and background, ensuring clarity of detail all over, however, if there is to be a specific subject to keep the focus on wide-angle lenses are not the ones to use.
Zoom lenses have a wide range of applications, from landscape to portraiture, allowing the photographer to either increase or decrease magnification of the subject. Their only drawback is that they are not suited to conditions where the light is dim, due to their narrow aperture. Many cameras come with a zoom feature already installed, but digital zoom lenses are quite different to optical zoom lenses.
While an optical lens magnifies the image, the digital lens actually enlarges and crops the image in the viewfinder. This can result in a poor quality image due to the low resolution, compared to the optical lens. So if you are after a camera with a zoom feature, go for one with an optical zoom; you’ll get better quality pictures.
A telephoto lens is similar to the zoom lens in that it is used for enlargement of the photo, but it works differently. While a zoom lens magnifies the subject, a telephoto lens actually brings the subject ‘closer’; effectively reducing the distance between the subject and the camera. A telephoto lens will show greater detail than the human eye could detect at the same distance.
Cheaper cameras often have a fixed, focal length lens. They sometimes do the work of a wide-angle lens - though not always - but are better in low light conditions. Many newbies have found they learn the basics of photography composition more quickly with this sort of lens simply because they have to put more thought into getting a quality shot.
The macro lens – often a built-in feature with today’s digitals - is for close-ups without distortion. Originally, it was an extension lens for optical cameras.
The fish-eye lens was developed for work in astronomy. It can take the wide-angle of the sky needed by those who study the stars. Landscape photographers who like the distortion of the curve often use it.
Front of lens accessory is a clip-on tool that mimics a lens. It gives additional options for a camera not built to take an additional lens, but without the quality a real lens would give.
