What does Quan Huafu mean?

There is a saying in the camera industry that "the bottom is too big to crush people." The bottom here refers to the frame, which is a special photographic term and refers to the area of the photosensitive element of the camera. Quan Huafu and half-frame refer to camera lenses with two different frames. Quan Huafu and half-frame are different in terms of frame, image quality, lens, price and body. Let's learn more about the difference between Quan Huafu and half frame. First, what is a picture?

Frame refers to the size of the photosensitive element area of SLR camera. Quan Huafu, also known as Quan Huafu, is a photographic term, which refers to the specifications of the photosensitive element with an area of 36×24mm; Half frame refers to the size of the photosensitive element, with an area of 22.7×15.5 mm. This specification is used to describe the imaging circle index of the lens and the size of the photosensitive element.

Second, the difference between Quan Huafu and half frame.

1, different frames

The exact name of the semi-graph is APS-C, and its size is much smaller than that of the full graph, and less than half of it is almost the same. Different frames have different high-sensitivity ability, that is, the ability to shoot dark areas is different. Where the light is poor, you can take a full picture and not see half of the things. In addition, it is very simple to shoot a small depth of field with blurred background in full frame, and it is more laborious to shoot in half frame.

2, the picture quality is different

The pixels are different, and the whole picture is larger than the half picture, so the picture quality is different, and the whole picture is clearer and more detailed.

3, the lens is different.

The lens is also divided into Quan Huafu lens and half-frame lens. Quan Huafu lens can be mounted on a half-frame machine, and half-frame lens cannot be mounted on a Quan Huafu machine. On a half-frame machine, the focal length of the lens should be multiplied by the coefficient of 1.5, which is called equivalent focal length, so Quan Huafu is suitable for wide-angle shooting and half-frame is suitable for telephoto shooting.

4. Different prices

In terms of price, Quan Huafu is much more expensive than half a frame. It is easy to understand that the size of the photosensitive element in Quan Huafu is larger than that of the half-frame photosensitive original, so the price is much higher.

5, the size of the fuselage

Quan Huafu's photosensitive original is relatively large, so the fuselage, volume and weight are larger than half a frame.
