Finding an affordable and high-quality digital camera

Finding a digital camera is not hard. After resolution, the most important factor to consider is the lens. To take good photos, the camera must have optical quality (glass, no plastic). Like the cheaper 35mm cameras, some digital cameras bring fixed lens (with no zoom), i.e. the lens is always in the same position and at the same angle of view. The only way here is to change the frame to a photo, zoom in or out of the subject or reason to photograph.

For example, we cannot always approach everything we want in our subject, and when we are, most of the lenses act like wide-angle fixed, which means that short distance will produce a significant distortion in the picture (the nose are larger, the eyes are separated, and the faces look like they are bent towards the camera).

The zoom digital camera lens, however, leave us without major problems closer to your subject without invading your "personal space" and eliminating the distortion mentioned above. We can also change the picture composition without leaving the place, zoom in or zoom out from a viewing angle of a wide-angle to a telephoto lens (and anywhere in between).

Also another advantage is that the zoom tends to "zoom in" distant objects. Typically, zoom lenses are characterized by the degree of engagement that place, which is nothing other than the difference between the wide viewing angle and minimum. For example, a 1:3 or 3x zoom means that the maximum zoom range is 3 times farther than the distance at wide-angle (ie, the minimum zoom). Obviously, this type of expensive digital camera lenses, but really worth it to have a good zoom and perhaps sacrificing megapixel resolution (obviously it depends on the end use will be given to the camera).

One thing to bear in mind is that many manufacturers advertise that their very digital camera models have "digital zoom" or "digital telephoto" but this is not really a lens, but what it does is stretch the original image more beyond its limits, which generally produces the pixilation or staggering. For this reason is that many manufacturers include within the functions of the camera image correction algorithms, once applied, gives the impression that "soften" the image. So, mark you when choosing a model that the camera has an optical zoom that magnifies the image by itself and not digital camera manipulation techniques (no problem if the camera has two types of zoom).
