"Full Frame" refers to a camera sensor size that is equivalent to a 35mm film frame, measuring approximately 36mm x 24mm. This larger sensor captures more light and detail, resulting in better image quality, especially in low-light conditions. Full Frame cameras are popular among professional photographers and enthusiasts for their ability to produce high-resolution images with a shallow depth of field. In contrast to smaller sensors, such as APS-C or Micro Four Thirds, Full Frame sensors provide a wider field of view and improved dynamic range. This makes them ideal for various photography styles, including landscape, portrait, and wildlife photography, where detail and clarity are essential.
