Zoom Lenses

• Conventional film cameras have only optical zoom, while digital cameras may have both optical and digital zoom features. Optical zoom lenses are usually considered far superior to digital zoom lenses. A camera with an optical zoom feature is much like any conventional camera.
  
  
• For everyday hobby shooting, however, it probably isn't necessary to buy such a lens. A mid-range zoom lens with an adjustable focal length will suit just fine for such purposes

• The fine focus ring is often positioned near the narrow eyepiece end of the zoom monocular. Magnification adjustments are usually made by turning the wider end of zoom monoculars to move the largest lens back and forth.
  
  
• If someone is an avid photographer or has the desire to take quality photographs from afar, then he or she will want to consider the level of optical magnification on a variety of cameras before choosing one. Digital zoom is typically not as effective. In addition, using this feature without understanding how it works can produce some very disappointing photographs.
