LENS
1.A good quality camera lens is essential for capturing sharp, detailed photos. There are dozens available, to suit every subject and budget.
2.There are many things that determine the quality of your photography, and one of the most important is the lenses you use. A good camera lens will capture sharp photos with plenty of detail and contrast, while a poor one can leave your images looking dull and blurry.
3.In photography and cinematography a normal lens is a lens that reproduces a field of view that appears "natural" to a human observer.
4.In cinematography a focal length roughly equivalent to twice the diagonal of the image projected within the camera is considered normal, since movies are typically viewed from a distance of about twice the screen diagonal.
5.A telephoto has a long focal length and provides a high level of magnification, allowing you to photograph subjects at a moderate to far distance. They tend to be bigger and heavier than other types of lens, although modern technological advances have made them more compact and easier to handle.
6..Telephoto lenses are popular for any type of photography where you can't get near to the subject, including wildlife and sports events. They are also commonly used in portrait photography, where a moderate telephoto lens will provide a natural, undistorted perspective.
7.A wide angle lens is one with a short focal length. They provide an angle of view beyond that of a standard lens, allowing them to capture more of the scene in a single shot.
8.Wide angle lenses are useful for photographing landscapes, cramped interiors, and other subjects which won't fit into a normal lens's field of view.
9.The most important factor in any camera lens is its focal length. This determines which type of lens it is, and what subjects it will be able to photograph. Focal lengths range from just a few millimetres up to over a metre.
10.Most modern camera lenses have a built-in autofocus mechanism which takes the guesswork out of getting sharp photos. Some specialist lenses may use a manual focusing system, so be sure to check this out before buying.
