What does aps-c frame mean?

With the same pixel, APS-C format camera can record more detailed information and brightness because of the larger photosensitive element area, and the picture performance is better.

The full name of APS-C is Advanced Photo System Classic, and the length-width ratio of its photosensitive element is the same as that of Quan Huafu, which is 3: 2. The size of APS-C is mostly around 25. 1× 16.7mm, but the actual size of each manufacturer will be slightly different. Compared with small format sensor, APS-C format sensor has a larger area, so it can capture more light and details. This means that APS-C format camera can provide higher image quality, better dynamic range and lower noise level with the same pixel. This makes APS-C format camera perform better in shooting scenes with rich details, high contrast and low light. Moreover, due to the large area of photosensitive elements, the depth of field effect of APS-C format camera is also shallower, which can achieve better background blur effect. These advantages make APS-C format camera a widely used choice in many photography fields.
