What's the difference between APS-C format and Quan Huafu?

Aps-c format and Quan Huafu, first of all, the sensor size, Quan Huafu is larger, so the picture quality is better, the high sense is better, and the effect is better in low light.

2. Control differences

Playing SLR, it's manual, and it's late Therefore, when the price in Quan Huafu is higher, manual control will be better, faster and more accurate.

3, the size of the field of vision difference

The size of the non-full-width photosensitive element is less than half that of Quan Huafu.

This difference is already great.

With the same lens

Non-Quan Huafu should be multiplied by the conversion factor 1.6 or 1.5.

Therefore, many theories about 135 camera are not applicable to non-Quan Huafu digital cameras.

The field of vision is obviously reduced.

4, the difference of resolution

If the pixels of the non-full-width and Quan Huafu are the same, the area of the non-Quan Huafu photosensitive element is small and the density is too high.

So there is diffraction when using a small aperture.

The picture quality will plummet.

And high density makes the lens a bottleneck.

Therefore, it is impossible to provide finer picture quality.

Therefore, non-Quan Huafu images are blurred and have low contrast and high sensitivity imaging with more noise.

5, the difference between dark corners

Dark corners are not easy to appear in the non-full width under large aperture, but they may appear in Quan Huafu. The main reason is that the lens, the larger the field of view, the greater the focusing effect of the lens, resulting in weak peripheral light and dark angle. However, the bright area in the center of the whole frame is small and concentrated, and the dark corner is difficult to appear relative to the whole frame.

There is also a P box for beginners. P mode is called panoramic mode, which blocks the upper and lower sides of the whole picture one by one, so that the aspect ratio of the picture is 3: 1. It will be easier for beginners to operate.
