A full-frame camera is a digital camera with a sensor that is the same size as a 35mm film frame (24mm x 36mm). This makes them ideal for professional photographers who need the best possible image quality and dynamic range. Full-frame cameras are also popular with enthusiasts who want the best possible image quality without having to spend a lot of money on medium format cameras.
There are many benefits to using a full-frame camera. One of the most important is that they have a wider dynamic range than APS-C or Micro Four Thirds cameras. This means that they can capture more detail in both the highlights and shadows of a scene. Full-frame cameras also have better low-light performance, making them ideal for shooting in dimly lit conditions.
