Choosing The Right Digital SLR Camera Lens for You – A Review
People often ignore or withhold on the camera's lenses, when shopping for a Digital SLR Camera.
Camera Lenses provide as the digital SLR cameras "eye," the lens influences what and how your camera will see your subject and how well that view is transmitted to the camera's sensor chip for recording. The way I like to inspect camera lenses is as painter's brushes, broad strokes, medium stokes, all purpose brushes, and small detail brushes. The next sections explain the basic types of digital SLR camera lenses, how they work, and how to select them.
Focal Length
Lenses can be categorized into subcategories like prime, macro, wide angle, normal, telephoto, and zoom lenses. They are also rated in regards to f-stop or speed an example would be a F2.0 50mm lens or a 1.4F 80mm lens. On a digital SLR camera the focal length of the lenses computes the distance between the lens and the image sensor, measured in millimeters.
Prime Lenses:
Usually prime lenses are sharper and faster then zoom lenses. Prime lenses are fixed focal length lenses like a 50mm 1.4f lens.
Macro Lenses:
Examples of macro lenses are 50mm and 100mm macros. These lenses are also groovy for discerning focus types of photos.
Wide-angle Lenses:
Wide-angle lenses are your wide stroke brushes; these types of lenses have short focal lengths. A technique to test if the wide-angle lenses you are interested in has convergence is to take test pictures before buying the lens. With high quality wide angles lenses like Canon L series lenses address this convergence issue well. Examples of wide-angle lenses are 15MM, 17mm, 24mm and 28mm lenses.
Normal Lenses:
If you buy just one lens try and buy the fastest normal lenses you can like a 50mm 1.4f lenses. Normal Lenses try to imitate how the human eye sees and are some of the most versatile lenses you can operate.
Telephoto Lenses:
Lenses with long focal lengths 100mm and higher are called telephoto lenses. Telephoto lenses also present your subjects a graphic look and flatten out your subject. These lenses are my short stroke brushes.
Zoom Lenses:
Zoom lenses are special because they can be very versatile. These types of lenses vary in their focal lengths and come in many in wide-angle, telephoto, and wide-angle to telephoto. In my bag I carry. With these three lenses, 17mm to 35mm a wide-angle broad brush, 24mm to 70mm a medium brush, and 80mm to 200mm a short brush can get a very board range of focal lengths for any condition. When shopping for zoom lenses examine the f-stop range rating. Zoom lenses can offer you flexibility and versatility all in one lenses.
