Executive summary about Digital Camera Lens by Fredrick Joy
It is very imperative to choose good quality camera lens. Lens is the vital element in a camera. Most of you buy digital camera without examining the lens in it. Always, make sure that you buy a very good camera lens as well as the camera. In some cases, it is not likely to change the camera lens. It is prudent to go for glass lens rather than plastic lens.
Ensure that the lens you buy suits your camera, because some cameras are restricted to specific lenses. The focal length of a lens is the measure of magnification and the view angle the lens supports. Focal length determines the type of lens and is measured in mm. Wide angle lens offers less magnification and wide view angle with a focal length of 20mm to 35 mm. Traditional lens provides a focal length of 50mm with normal magnification.
Zoom lens bids a focal length between 50mm to 150 mm and it alters its focal length while zooming in. Zoom lenses are largely preferred these days. A few lenses can be interchanged between digital camera and film camera. Sundry camera models have different lenses in them.
Some models like super zoom are not exactly Single Lens Reflex model, even though they possess some features like SLR features.
