WebIf this is the case, then lens selection becomes much easier. For example, assume that an FOV of 175mm needs to be achieved with a 500mm WD on an IMX250 sensor (2/3”, 5 MP). Using Equation 3, a 25mm lens is the best choice. In general, when lens calculators are used online, they are using some form of Equation 3 to generate their answer.
