Full-frame

Photo / Video

A camera sensor roughly the size of a single 35mm film frame (about 36×24mm). Because the sensor is physically larger than APS-C or Micro Four Thirds, it captures more light for a given exposure, which generally translates to cleaner images in low light and the ability to render a shallower, more out-of-focus background at the same field of view. Those advantages typically come with higher body and lens prices and more weight to carry. Concrete example: at the same aperture and framing, a full-frame shot will usually show more background blur than an APS-C one. Buying impact: choose full-frame if low-light work or maximum background separation matters most, and APS-C or smaller if budget, size and reach are higher priorities.
