How Do I Choose A DSLR Lens?

Choosing a DSLR lens is a task that can easily overwhelm even the most experienced photographers. With so many lenses on the market to choose from, how do you know which one will suit your needs? This blog post provides an overview of some of the most popular models and features for each lens. It also includes helpful buying tips and some alternatives to consider.

  • Aperture: The aperture is the opening in the lens that allows light to enter. The size of this opening is measured by f stops that go from 1.0 (large opening) to 22 (smallest opening), with higher numbers representing smaller openings.
  • Image Stabilizer: Image stabilization technology helps to reduce blur caused by camera shake. It can be either internal (embedded in the lens) or external (attached to the camera).
  • Focal Length: A focal length is the distance between the center of one subject and the center of the main (focal) point.
  • Focal Length Range: A focal length range shows how many different focal lengths are available for that lens, from an extreme telephoto to a wide-angle view. This can be determined by looking at a chart with specific numbers (e.g. 15-35mm, 24mm) or by looking at the model on the lens or camera body.
  • Color Refractive Correction: This is the ability of a lens to compensate for lens chromatic aberrations that occur when different wavelengths (colors) of light focus at different positions.
  • Autofocus: Auto focus means that the camera will automatically adjust the focus of an image, so no adjustments are needed by hand. There are generally two types of autofocus: phase and contrast detection. Phase detection is faster because it uses a sensor to help locate sharp focus points.
  • Distortion: Distortion is a distortion that can dramatically change the dimensions of the image.
  • Aperture Range: This is the maximum and minimum f-stop (size of aperture opening) offered by a certain model.
  • Macro: A lens is considered to be a macro when it can focus on items as close as 25-50cm from the camera.
  • Macro Reversal Focusing: Macro reversal focusing means that the lens can be removed and reversed to achieve extreme magnification. Wide-angle lenses are often used for this purpose.
  • Focusing Ring: The focusing ring is the ring on the lens that allows movement of the lens elements to adjust focus.
  • Quick-Shift: Quick-shift refers to a feature that allows for instant manual focus override, very useful for moving subjects.
  • Silent Control: This feature, also called Stepper Motor, allows focus override without having to touch the lens. Simply turn the focusing ring to adjust focus manually and then turn it back again to lock in your desired focus point.
