<human>:  What is the difference between a full frame camera and an APS-C camera?
<bot>: The main difference between a full frame camera and an APS-C camera is the size of their sensors. A full frame sensor is approximately 35mm by 24mm in size, while an APS-C sensor is much smaller, usually around 22.5mm by 15mm. Because of the larger sensor size, full frame cameras typically have a more shallow depth of field, allowing photographers more creative flexibility when shooting. Additionally, full frame cameras tend to have better image quality and higher ISO performance than APS-C cameras.
