Key differences between DSLR full frame cameras and half frame cameras? What are the advantages over half-frame?

A, full-frame camera and half-frame camera differences:

1, the size of the sensor is different: full-frame sensor size of 36 * 24mm, half-frame camera sensor size of 22.7 * 15.5mm.

2, the size of the camera body is different: due to the size of the sensor is different, in general, the full-frame camera than the half-frame camera is bigger.

3, suitable for shooting different things:Full-frame cameras are suitable for shooting large buildings and landscapes due to the larger picture, while half-frame is suitable for shooting portraits, pets and other small objects.

4, ISO performance:Full-frame can provide better image quality performance at high ISO compared to half-frame. A half-frame camera like the D5500 has a 24-megapixel image sensor, the same as the full-frame D750.

However, because of the larger area per pixel on the D750, they are more sensitive to light. Accordingly, the same low-light performance is better on full-frame.

2. Advantages of full-frame over half-frame

1. The image quality of a full-frame camera is clearer and grander than half-frame.

2, full-frame cameras have stronger color expression than half-frame.

3, full-frame cameras have better high-sensitivity image quality than half-frame.
