What is Biscuit Head?

The biscuit head refers to a type of SLR lens that is very short (that is, very thin). Because it looks like a biscuit, it got the nickname biscuit head. In order to pursue the ultimate compact size, this type of lens does not hesitate to sacrifice the size ratio of the maximum aperture and even the image quality of the lens. The maximum aperture of the biscuit head is generally only F2.4-2.8. Advantages of the biscuit head: 1. Small, allowing the entire lens to be easily put into a pocket. 2. Fast, the focusing speed is unmatched by zoom heads. 3. The "fast" large-aperture aperture makes the shutter speed much faster and has better ability to capture the moment. 4. The viewing angle is fixed. Once you are familiar with it, you can shoot blindly (without looking at the viewfinder) or carry it with you. You can complete shooting preparations as soon as you take out the camera. It can freeze wonderful moments without attracting attention. A camera that does not require a viewfinder is a powerful tool for humanistic photography. The works of some masters are masterpieces of this type of camera.
