A camera model refers to a specific design or version of a camera produced by a manufacturer. Each model typically has unique features, specifications, and capabilities that distinguish it from others. For example, different models may vary in sensor size, resolution, lens compatibility, and additional functionalities like video recording or connectivity options. Camera models are often identified by a combination of letters and numbers, such as Canon EOS 90D or Nikon D3500. These identifiers help consumers and professionals choose the right camera for their needs, whether for casual photography, professional work, or specific genres like landscape photography or portrait photography.
