SLR lenses hugely vary from one to another. Although they may give the same attributes for example the range of millimeter it can achieve, every version is however mismatched with different digital camera.
A Nikon lens is really not compatible with Canon cameras, the other way around. However, many of the lenses nowadays are exchangeable between the various types of the same brand. Say for example, an 18-55 mm kit lens of Nikon D80 will definitely fit into the Nikon D90 digital camera model.
So whatever digital camera you own, the SLR lenses vary significantly in function, measurement, cost, and can be typically placed under the following classes:
Standard lenses are actually the first lense you will possess in getting an SLR camera. Standard lenses are included in the camera kit. It provides simple feature that is made to have a wide variety of photographs. It takes photos really like what our eyes can see. It provides a very normal range of captivity and cannot therefore take of those with longer range view.
2. Wide Angle
Wide angle lenses provide a shorter focal length compared to those of the standard SLR ones. Hence, wide angle lense make a wider angle image. Its special photo effect creates the closer to subject near the camera a whole lot bigger than the other objects captured. It makes a distortion on the picture's viewpoint, creating a superb looking image. One great instance of a wide angle lens is the fish-eye lens.
3. Fish-eye Lens
Fish eye lenses are often used only for producing special photo effects. It is not regularly used in general photography. Associated to the type of wide angle, fish-eye gives the photographs quite distortion taking it to another perspective of being impressive. It generates a wider view and offers an unusual photo effect making one fantastic image.
Telephoto lenses are the kinds of lenses which differ tremendously in value. It costs a way lot compared to those of the standard and wide angle models. These kinds of lenses price mostly up to $100000, especially those of the high end brands. Yet beginners have found some that cost $1000. Telephoto creates a great feature that can get those of distant ranges. It features to create the target quite nearer just like a pair of binoculars or a telescope can do. It is almost always useful for wildlife and sports photography.
Macro lenses are the opposite form of lenses to the Telephoto. It makes each and every small thing quite bigger with its lens. It is mainly used for biological experimentations that even the tiniest insect can be zoomed much bigger in a picture with no distorting any of the forms and pixels.
