“Close up” or macro:
This is an essential device used on a large scale in different cameras and camcorders. The gadget is mainly used for “close-up” photography. It primarily generates an image on a focal plane that is larger or similar in size of the subject being captured.
A macro lens can be of any focal length. The prominent factors that determine the focal length of the device include its practical use, access to the subject, considering magnification, the required ratio, illumination considerations, etc. The depth-of-field of the device is very slight, which limits its usefulness.
This is another important type of lens. The focal length of the device varies with the movement of internal elements. Generally, the lens zooms from moderate wide-angle to moderate telephoto or from normal to extreme telephoto. The devices are mostly used for small-format cameras. These are not used for larger film sizes because of their price and bulky nature.
This category includes a wide range of devices such as an apochromat, a process, enlarger, stereoscopic, fisheye, soft focus, infrared, ultra-violet and a swivel lens.
