Re: Calculating Focal Length on Camcorder

That's going to be tough.

Unless your camera has interchangeable lenses -- and I doubt that it does -- its lens will probably have a zoom ratio and a minimum and maximum focal length. You would then need to know how much you're zoomed in, and you could calculate the current lens focal length.

Your camera may have a menu setting that will display the amount of zoom. If it doesn't, you'd have to guess at it.
