What is a crop sensor (APS-C)?

A crop sensor (APS-C) is a camera sensor that is smaller than a full frame sensor — typically around 22mm × 15mm on Canon bodies and 23.5mm × 15.6mm on Sony, Nikon, and Fujifilm bodies.
The name “crop” comes from the fact that it captures a cropped portion of what a full frame sensor would see using the same lens.

The Crop Factor

Because the sensor is smaller, it doesn’t capture the full image circle projected by the lens. This creates a magnification effect called the crop factor:

Where APS-C actually wins?

People talk about full frame like it’s always better — but APS-C has real advantages:

If your budget is under 40,000–50,000 EGP, an APS-C camera with a good lens will almost always give you better results than stretching to a budget full frame body with a kit lens. The sensor format matters far less than the glass in front of it and the light you put on your subject.
