The lens is a device made of glass or plastic, good type. Have a look round, smooth surface is divided into two types, namely lenses, concave curvature and lens Assembly will be located at the front of the camera to shoot several characteristics requires selection of lenses to use properly the lens so there are several each with unique features to options, but before I get to know the characteristics of the lens, and the properties of each lens. Necessary to know the focal length of a lensThe type of lens. From the properties of the lens, so enough to split out the lens, as the lens's properties. 1. standard lens (Standard Lens) refers to a lens used to shoot locations, see General non-profit special. Suitable for landscape photography or images of the typical standard lens that came with the camera, generally in large part will have a focal length of 50 mm. 2. wide angle lens (Wide angle Lens-a) is a lens with a focal length shorter than a standard lens or lenses used in normal shooting, the common use of this wide angle lens photography coverage than conventional lenses, and have depth throughout the image is obviously from close range until the remote but the image will be distorted in the size of the image because the subjects are close to larger is not proportional to the remote section. Wide angle lens will mostly take in places that could not be farther away from the camera to the shooting were much like capturing buildings, opponents who want to be in all the pictures, but was unable to find the angle because I've stuck to walls, obstacles such as rivers, etc.3. the distant lenses (Telephoto Lens) lens is more than a standard lens focal length coverage taking less than this type of lens is also known as the narrow-angle lens (Narrow angle Lens), the advantages of distance lens is able to shoot at objects in the distance, as if the object came near is expanding far images clearly. The images in this manner, such as photography, wildlife photography, sporting events, etc., the lenses may be divided into 2 types of lenses far moderate type. (Medium telephoto lenses), the focal length is between 75-200 mm lens is a special type of distance (Special long telephoto lenses) is a lens with a focal length greater than 250 mm or more. 4. fish-eye lens (Fisheye Lens) is similar to the eye of the fish swimming in the water. Eat in the corner, shooting range up to more than 180 degrees wide lens, it has a depth of field is greater than the other lenses. This type of lens is ideal for those who want a picture in picture effect to other anyway, because this type of lens, image size, full size, rectangular or circular images, film on film. Objects that have been taken will be very large. 5. zoom lens (Zoon Lens) is the lens focal length, multiple values in the same is both standard and wide-angle lenses in the same result as a lens that has a relatively high rate than other lenses, so users are comfortable than not must move in order for shooting too much. But it has the disadvantage of a zoom lens is heavier because it contains a set of lenses than the single channel. The aperture at the wide end of the zoom lens is also narrower than the single focal length lens and image problems may occur with the wrong proportions over peripheral areas in particular. 6. macro lenses (Macro Lens) lens is used, taking very small objects. Enlarged close-up lenses, similar to, but this is a macro lens a lens can photograph objects close to the overboard around 1-1.5 ft. Sometimes referred to as micro lens (Micro Lens)
