insight Digital Camera Zoom Lenses

There are two types of zooms used with digital cameras: optic and digital.

Optical Zoom

An optic zoom changes magnification by bright glass in the lens, changing the image falling on the sensor. Using an optic zoom maintains picture quality.

Zoom Ranges and 35mm Equivalents

Optical zoom lenses regularly have a specification called “equivalent in 35mm.” This tells you the zoom range of the digital camera compared to a 35mm film camera. Typical 35mm equivalent zoom ranges you will see listed are 35mm-70mm or 35mm-105mm.

For example:

Wide-angle means a lens takes in more than general viewing perspective. Telephoto lenses magnify the subject, bring it closer. Using these numbers as a guide, you can get an idea of the range of zoom lenses and what they will do for you.

28mm…..wide angle

35mm……slight wide angle

50mm…..normal perspective

70mm…..slight telephoto

105mm…..moderate telephoto

135mm…..strong telephoto

200mm+…..extreme telephoto So, a 35mm-105mm equivalent zoom lens changes from a miniature wide angle to a moderate telephoto. A 28mm-200mm equivalent lens changes from a wide angle to an greatest telephoto.

A 35mm-105mm equivalent zoom is enough for most users. If you plan on doing landscapes or picture taking in small, confined areas, reconsider a camera that can zoom to a 28mm equivalent.

Optical Zoom as 2x, 3x, 5x…

Taking the 35mm-105mm example above, we divide 105 by 35 to get a 3x zoom. A 28mm-105mm would be practically a 4x zoom, and a 35mm-350mm would be a 10x zoom.

Digital Zoom

A digital zoom does not change, magnification. It plainly crops the image on the sensor to magnify the image. Because less sensor is used, you use fewer pixels. This decreases picture quality. When comparing cameras, always use the optic whole as this is much more important. You can get the same result as a digital zoom by using software to crop the photos.

Note About Digital Zoom

As digital cameras come to be more sophisticated and marvelous they are becoming capable of delivering “optical tricks” that render pictures that are remarkably carport and good looking. Only recently, cameras “digital zooms” are getting much better. Like all things though some associates are best than others. Do your research.

Digital Camera Lenses

The need for camera lenses changes with what kind of camera you have. If you have the common digital camera then you admittedly do not need to have lenses. However if you have the Slr then you will most likely need to get lenses but you must make sure that they fit your camera.
