Focal length calculator from Goyo North America computes effective focal length

A Focal Length Calculator web tool allows users to calculate the most effective lens focal length for their systems, ensuring the aspect ratio of the sensor size equally pairs with the aspect ratio of the object being imaged. Using sensor size, working distance, and field of view (FOV), it computes the effective focal length (EFL) while providing the best lens option.
