Focal length is a term used in photography that tells us how far the lens is from the image sensor when the photo is clear and in focus. It is measured in millimeters (mm).

Let’s break it down by different types of focal lengths:

• Short Focal Length: (like 18mm to 35mm)

  • Gives a wider view
  • Perfect for taking pictures of landscapes and buildings
  • Creates a broader depth of field (DoF), meaning more of the picture is in focus.

• Standard Focal Length: (around 50mm)

  • Offers a natural and familiar view
  • Best choice for taking portraits or close-ups of people.

• Long Focal Length: (between 85mm and 400mm)

  • Helps you zoom in on things far away
  • Great for photographing wildlife and sports activities
  • Provides a narrower depth of field, focusing more on the subject and blurring the background.

When you increase the focal length by just 1mm, it can really change how the picture looks. This affects the way you frame your shot and what perspective you get.
