Digital Camera Lenses

Most SLR Digital Cameras use interchangeable lens systems which means you can remove the lens from the body of the camera and replace it with a different lens. Depending on your needs, you may want to have a few different lenses in your Case. With a Digital SLR Camera, you have the ability to prepare yourself for all occasions and scenery with different lenses. If you've been using 35mm cameras for a long time and you already own some lenses, there may be a Digital Camera body that will fit those lenses. Likewise, if a new and improved lens hits the market, you won't have to buy a whole new Digital Camera, simply purchase the lens and affix it to your camera.

When researching a Digital Camera Lens, keep in mind the Focal Length of the lens. A so-called "short lens" has a wide angle of view, while a longer focal length will narrow the angle of view. Since a Zoom Lens has a lengthened focal length, your field of view will be smaller, but you will be able to see much closer than with the naked eye. Likewise, a Macro Lens enables you to view tiny objects, akin to a microscope, but your field of view will be very limited. Some Digital Cameras have internal Zoom and/or Macro functions, but if you have a Camera with an interchangeable lens system, you can click on our top rated retailers to purchase lenses to suit your specific needs.

Digital Camera Resolutions

Before you even start shopping for a Digital Camera and comparing brands and features, you need to figure out the number of Megapixels that you need. As opposed to non-Digital Cameras that use film to capture and store an image, Digital Cameras use an image sensor to store varying degrees of light and brightness onto a grid of photosensitive diodes. When the shutter is opened (meaning that you are taking a picture), each individual diode captures a different intensity and color of light. Each diode assigns a numerical value that can later be translated to hue, color and saturation for the purpose of viewing and printing those pictures. The more diodes you have on this grid (DPI) the higher quality image you will be able to extrapolate and print.
