Field of View (FoV): total area that can be viewed by the lens and imaged onto the camera sensor. Working distance (WD): object to lens distance where the image is at its sharpest focus. Depth of Field (DoF): maximum range where the object appears to be in acceptable focus. Sensor size : size of the camera sensor's active area. 11. Focal length is the distance between the lens and the focal point: At focal point the image is sharp and it's the place where the camera sensor is located (or camera film). The Field of View of each lens depends on the sensor size: The conversion formula is this: FOV = 2 * arctan (half_the_diagonal_of_sensor / focal_length) Blender allows Due to similarity in name and nature, depth of field (DOF) and depth of focus are commonly confused concepts. To simplify the definitions, DOF concerns the image quality of a stationary lens as an object is repositioned, whereas depth of focus concerns a stationary object and a sensor's ability to maintain focus for different sensor positions, including tilt.
Focal lengths range from the widest wide angle (28mm or lower) to super-telephoto (300mm or higher). The higher your focal length, the shallower your depth of field is going to be. The lower your focal length, the deeper your depth of field is going to be. However, it's important to know that the focal length of a lens will affect your images

What is depth of field (DOF) The simplest definition for depth of field is the area of your image that is in focus. More specifically, the distance between the nearest and the farthest object that are in focus.

Extended depth-of-focus (EDOF) is a new intraocular lens (IOL) technology in the treatment of presbyopia. In contrast to multifocal (MF) IOLs, EDOF lenses create a single elongated focal point, rather than several foci, to enhance depth of focus. In this way, EDOF IOLs aim to reduce photic phenomena, glare, and halos, which have been reported dsuklW.
