There are specialized lenses used in still photography in order to increase or alter the quality of photograph or set the angle of view of photos. Let's go through and choose the correct for your photography.
A macro lens is classically a lens capable of reproduction ratios greater than 1:1, although it often refers to any lens with a large reproduction ratio, despite rarely exceeding 1:1.
It's a photographic lens whose focal length is fixed, as opposed to a zoom lens, or it is the primary lens in a combination lens system. It can add quality in pictures and a soft focus effect.
An ultra wide-angle lens is a lens whose focal length is shorter than the short side of film or sensor. Any lens under 15 mm has considered as ultra wide lens in still photography.
Apochromat Lens,is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses.
A swivel lens is a lens that freely rotates while attached to a camera body. They are used on some compact digital and video cameras (camcorders). These lenses make it easy for a photographer to aim a camera without moving around too much.
