Interchangeable lenses are lenses that can be detached from a camera and replaced with another lens, providing photographers with greater flexibility in capturing different types of images. This feature is common on 35 mm SLR cameras, mirrorless systems, and many medium-format cameras.
Using interchangeable lenses allows photographers to switch between wide-angle, standard, telephoto, macro, and specialty lenses depending on the scene, subject, or creative intent. Understanding and using interchangeable lenses effectively enhances versatility, composition, and overall image quality, making it a crucial aspect of professional and enthusiast photography.
