Thanks, that helps a little, but I was hoping that either someone a) had experience filming a tennis court, or b) knew how to calculate the Field of View. I mean, I can go to Wikipedia and look up the calculation, but what is the focal length of the gs500? The ccd is listed at 1/4.7 inches and I can convert that to mm, but the focal length is variable from 2.8 to 39 mm?? What would you use for this measurement?
Like I say, I like math as well as the next guy, but there has to be an easier way to figure out how to get 90 degree field of view!
Another question – will a 90 degree angle make it look like a fish eye?? 🙂
