Megapixel FA lens, FA & image processing/security
*The following text is an excerpt from the "FA Dedicated Catalog." For details, please refer to the "FA Dedicated Catalog."* 1. Calculation method for determining focal length (W.D) When determining the distance from the lens tip to the subject (= W.D), it is possible to apply the sensor size of the camera being used, the focal length, and the dimensions of the subject into a formula for calculation. (Some parts omitted) 2. Calculation method for determining focal length If the dimensions of the camera and subject, as well as the distance between the lens and the subject (= W.D), are known, it is possible to derive the theoretical optimal focal length using a formula. (Some parts omitted) 3. Sensor size ● Lens selection It is necessary to select a lens that is compatible with the camera's sensor size. → A lens marked with "Compatible Sensor Size: 1/2 type" can also be used with a camera that has a smaller 1/3 type sensor. However, it is not suitable for a camera with a larger 2/3 type sensor. (Some parts omitted) 4.

basic information
1. Method for calculating focal length (W.D) The distance from the lens tip to the subject (W.D) can be calculated using the following formula. <Formula> W.D = H1 + y × f / y’ f: focal length H1: position of the first principal point y: vertical dimension of the subject y’: element size (vertical) Distance from the lens tip to the subject (W.D) = 26.77 + 120 × 25 / 6.6 = 481.32 mm 2. Method for calculating focal length By substituting the necessary values into the following formula, the theoretical optimal focal length can be derived. Based on the obtained solution, it is possible to select the lens. <Formula> f = y’ × W.D / y f: focal length W.D: distance from the lens tip to the subject H1: position of the first principal point y: vertical dimension of the subject y’: element size (vertical) 3. Element size When selecting a lens, it is essential to first choose one that is compatible with the camera's element size… (Continued omitted) *For details, please refer to the "FA Dedicated Catalog." 4.
