Hi, I'm hoping someone might be able to point me in the right direction. I'm putting together a bid for a seminar shoot and I'm considering using the HPX500's. I like the chip and the lens is much more practical than my HVX200a! It's a Fujinon XA17x7.6BRM 17x 2/3". I've spent the last hour or so looking for an online guide so I can calculate what I can expect in terms of throw. The focal length is 7.6-130mm.
