Select the Right Zoom Lens When Purchasing Your New Point and Shoot Digital Camera
When you’re shopping for a point and shoot digital camera, you want to make a checklist of the major features that will help you decide which camera to buy. In this article we discuss the zoom lens and how it is important to choose the right zoom lens features when selecting your camera.
A zoom lens lets you change the focal length of the camera. This means simply that the lens lets you choose how much the camera will magnify the image by zooming in and out of a scene when you are composing your shot. Generally, the higher the zoom magnification, the better.
You will commonly see cameras sold with magnification of 2x, 3x and even 5x on some better point and shoot cameras. Make sure that the zoom refers to optical zoom. The optical zoom refers to movement of the elements in the lens to perform the magnification. This type of zoom will ensure your images are in sharp focus throughout the camera’s entire zoom range. You should also check to see that the optics are made of glass and not plastic. A glass lens will give you better images without distortion. This is what the best 35mm camera lenses – Nikon, Leica, Canon – have and it’s what you should also demand in your point and Shoot Camera.
There is another type of zoom called digital zoom. Digital zoom does not use optics to magnify an image, rather it simply takes a group of pixels in the image and processes them to make them look bigger. The result is the image will be blurry and grainy. This is not what you are looking for.
When comparing cameras, ignore the digital zoom and look only at the optical zoom since that will tell you the real capabilities of the camera.
