A crop sensor is a type of image sensor used in digital cameras, particularly in the context of photography and videography. It is smaller than a full-frame sensor, which means it captures a narrower field of view. This results in a crop factor, typically around 1.5x to 1.6x, effectively magnifying the image. Crop sensors are commonly found in entry-level and mid-range cameras, making them popular among amateur photographers. These sensors are advantageous for certain types of photography, such as wildlife or sports, where the extra reach can be beneficial. They also allow for lighter and more compact camera designs, making them easier to handle. Many brands, including Canon, Nikon, and Sony, offer cameras with crop sensors, catering to a wide range of users.
