Canon is a top camera company that produces not just cameras but accessories. Canon lens are made to be interchangeable with most cameras. Camera Lens are an essential tool to the photographer. Each lens provides a different service to the user. Some of the more common uses are: to get a closer shot, color balance, and other visual effects.
This means more light enters the camera. Since it begins to collect additional light, a type of lens that allows you to open to a wider aperture also enables you to have a faster shutter speed. Such feature is essential in low lighting conditions to obtain sharp images, especially through a handheld camera.
When shopping for a Digital SLR Camera people often overlook or skimp on the camera’s lenses. Camera Lenses serve as the digital SLR cameras “eye,” the lens determines what and how your camera will see your subject and how well that view is transmitted to the camera’s sensor chip for recording.
It is the actual distance in-between the focal lane of the lens and the rear element, measured in millimeters (mm). This is where the light’s parallel beams enter the lens converging onto a point. It determines the viewing angle of the lens. It is one of the mechanisms that control the actual “amount of light” passing through the lens towards the image sensors. It is also referred as “f-stops,” like f/2/8. The smaller the number, the larger the opening.
Zoom Lenses are for those wishing to get action photos, the best would be the “telephoto lens” which ranges from 100mm up to 300mm. This is due to the DSLRs crop factor. There is not much zooming needed. A good example would be Nikon D40 which has a 200mm type of telephoto lens that can turn into a 300mm one.
Prime lenses are fixed focal length lenses like a 50mm 1.4f lens. To zoom with these types of lenses you need to use your feet and to get closer or farther away from the subject. Traditionally prime lenses are sharper and faster then zoom lenses. If you are on a budget you can pick up some amazing used older prime lenses off eBay or your local camera store.
