Guide to Understanding Your Macro Camera Lens

A macro camera lens is designed especially for close focus work. The design mainly boasts of a long barrel that can pick up 'micro' images like snowflakes, textures and small yet well detailed objects. Here are a few points to understand the lens and the way it works.

Purpose

A macro lens is designed to capture and produce pictures/images at a life-like size. The ratio is around 1:10 to 1:1. The current lenses in the market have a focal length ranging from around 50 mm to 200 mm.

Choice of Focal Length

Among the variable focal lengths available, the one that you must choose is dependent on the subject you plan to photograph. If you want to include the background, then a wide-angle lens (50 mm) would serve well. However, if you plan to focus on the object while remaining at a distance (and yet get all the textural details), then a telephoto lens would be more suitable.

How to Get the Best out of Your Lens

  • Use a tripod while shooting to avoid any shaking of hands, as the clarity and details are the mainstay of the lens.
  • Give ample distance between the camera and subject while setting up a shot, so that accessory equipment can be placed in between as required
  • Make sure that the background is clear and not a riot of colors, as it takes focus away from the subject. Use a large aperture that will help get a depth of field that is shallow enough to blur out the background.
  • Always prefer to focus the camera manually to get the parts of an image you want to be clear.
