Crop sensor cameras, also known as APS-C cameras, have a smaller image sensor compared to full-frame cameras. This smaller sensor results in a crop factor, typically around 1.5x, which means that the effective focal length of lenses is increased. For example, a 50mm lens on a crop sensor camera behaves like a 75mm lens on a full-frame camera, making these cameras popular for wildlife and sports photography. These cameras are often more affordable and lightweight, making them accessible for amateur photographers. They also offer a wide range of lenses and accessories, similar to their full-frame counterparts. Many brands, including Canon, Nikon, and Sony, produce crop sensor models, catering to various photography needs.
