In the most general terms, there are normal lenses, short lenses and long (telephoto) lenses. For most film-loaded SLR cameras the normal lens is 50mm. What is normal for one camera is not necessarily normal for others. Normal lenses minimize certain distortions that are inherent in longer or shorter lenses, and produce images that are proportionally most like the way the photographer actually viewed the scene when the image was made.
There are lenses that support automatic focus and others that have to be focused manually. There are also zoom lenses that can be adjusted to work over sometimes quite large ranges of focal length; generally there may be some compromise in lens/image quality with some zooms; they are tempting and fun, but be sure you need one before you put out the money. Expensive lenses WILL NOT compensate for sloppy technique.
There are probably thousands of different lenses available at any given time, over a dizzying range of prices and for any number of specialized applications.
When being used in photography, a telephoto lens is used as a long focus lens. This means that the focal length of the lens is longer than the physical length. This type of lens is often used for photography of animals.
The camera that is best used for crime scene photography is a single-lens reflex camera, also known as SLR. This camera allows you to use interchangeable lens.
A matte box in terms of photography and video is used on the end of a lens to block lens flare, glares and sunlight. Matte boxes are also used to hold filters in place.
Glass was used as a lens protector. Now we use plastic.

There are many good Nikon lens for portrait photography. However, perhaps the best Nikon lens for this purpose is the Nikkor AF-S 50mm f/1.4G lens. The cost of this lens is approximately $450.00.
High shutter speed and fast lens/Big open aperture.
Fast, telephoto lens
24-105MM Zoom Lens is the best for me.
any lens can be used, but if you are dealing with a more dangerous animal, you should use a bigger/longer lens so you can get good pics while still being safe. But if you are closer, you can use a smaller lens if it is not a dangerous animal. It really doesn't matter, there's no right or wrong lens.
Camera Labs recommends a different lens depending on what type of pictures one is taking. The Sony Alpha lens should be used for general purpose pictures and low lighting photography. The recommend a telephoto lens for sports and a macro lens for close up photography. One when is taking pictures of landscapes or big objects they should use a wile-ablge lens.
