A 24mm lens is a type of wide-angle lens commonly used in photography and videography. It has a focal length of 24 millimeters, which allows for a broader field of view compared to standard lenses. This makes it ideal for capturing landscapes, architecture, and group photos, as it can fit more into the frame without needing to step back. In addition to its wide perspective, a 24mm lens often produces minimal distortion, making it suitable for capturing details in a scene. Many photographers prefer this lens for its versatility, as it can also be used for street photography and environmental portraits, providing a natural look while still including the surroundings.
