What's the difference between aps and aps-c format?

This is the most obvious difference. Take a picture of aps-c and aps. The size of photos is different, and the pictures that can be accommodated are different. Quan Huafu can take much more than half.

2. Different lens groups can be used.

Unless you buy a special switching device, half of the lenses with special APS-C can't be used in Quan Huafu.

3. Image quality (parameter difference)

The difference of image quality is huge, depending on the parameters. Quan Huafu's cameras have different shutter speed and ISO density. There will be a lot of noise at half a width of ISO 1600, and it may be clear for Quan Huafu to drive to ISO3200.

4. Different prices

The price in Quan Huafu is more than half of this price.

5. The weight of the camera

Quan Huafu is heavier than a half frame because there are more accessories in the machine. Of course, it is also heavier because of its configuration and fuselage material.

Extended data

The imaging element of APS-C is smaller than that of Quan Huafu, so when the lens of a full-frame camera is installed in an APS-C camera, the images obtained are different. Because the imaging area obtained by the light passing through the Quan Huafu lens is larger than that of the sensor, the image obtained by the sensor will have a feeling of "the picture is cut" compared with that of the Quan Huafu sensor.

For example, a 28mm lens is used as a wide-angle lens in a full-frame camera, but when it is used in an APS-C camera, the imaging area is narrowed and becomes a standard lens. If you want to know what the focal length of Quan Huafu lens on APS-C is comparable to that of a full-frame machine, you must first know the conversion rate.

For example, if the conversion rate is 1.6 times, the 28mm wide-angle lens becomes 45mm, which is the standard lens. But this value only describes that the viewing angle is equivalent to the focal length of a full-frame lens, and the perspective relationship will not change. For example, a fisheye lens with exaggerated distortion effect will not become a wide-angle lens.
