A mirrorless camera is a type of digital camera that does not use a traditional mirror reflex mechanism like those found in DSLR cameras. Instead, it uses an electronic viewfinder or the main digital display to preview images. This design allows for a more compact and lightweight camera body, making it popular among both amateur and professional photographers. Mirrorless cameras offer interchangeable lenses and advanced features, often matching or surpassing the image quality and versatility of DSLRs. The absence of a mirror also enables faster shooting speeds and quieter operation.
