High Speed Auto Focus Electronic Iris Aperture Diaphragms for CCTV Lens Security HD camera ATM-SU-115
The smaller the aperture, the more focused the light will be, allowing for a larger depth of field (DOF) – covered in more detail later. This is inversely proportional to the amount of light that reaches the sensor. So, when trying to achieve a bright and focused image, aperture plays an important role. However, sometimes its relationship with focus and brightness might not be desirable. This blog covers the different ways to adjust aperture, how to take advantage of its optical impact, and provides alternative options for getting bright and focused images in various conditions.
What is aperture?
The aperture of a lens is the opening through which light passes to reach the camera. Adjusting the aperture means making that opening larger or smaller with a lens diaphragm usually made up of metal blades or leafs within the lens. The number of blades within the diaphragm can vary significantly
