Is canon 100D full frame

No, the Canon 100D, also known as the Canon Rebel SL1, is not a full-frame camera; it features an APS-C sensor. Full-frame cameras have a larger sensor size equivalent to 35mm film, whereas the APS-C sensor in the 100D is smaller, affecting depth of field and field of view. This makes the 100D more compact and lightweight, suitable for entry-level photographers.
