What are the characteristics of the full-frame machine? Compared with the half-frame machine.

The main difference between Quan Huafu and half-frame. Simply put, standing in the same position, shooting the scene or object in front of you at exactly the same angle, equipping the camera with exactly the same lens and adjusting it to the same focal length, the full-frame camera can get a larger field of view than APS-C or 4:3-frame camera, and there is a significant difference in imaging range between them. In layman's terms, a half frame is actually a part of the image cut in the middle of Quan Huafu.

That is to say, the actual focal length of the half-frame display is a multiple of the lens focal length, Canon is 1.6, Nikon is 1.5.
