Telephoto Lens Systems

Telephoto lens systems are specialized camera lenses designed to magnify distant subjects, bringing faraway objects closer for detailed viewing or photography. They achieve this by using a combination of glass elements and a longer optical path, which effectively increases the focal length—the distance from the lens to the image sensor when focused at infinity. This design allows photographers to capture clear, close-up images of subjects like wildlife or sports from a distance, without physically moving closer. Telephoto lenses are essential for situations requiring detailed distant imagery and are widely used in photography, videography, and surveillance.
