Hi I'm trying to find out how to work out the hyperfocal diastance on a tv broadcast zoom lens the particular lens im using is a Fijinon 10x4.8 However knowing how to do that should apply to and lens The camera I'm using is a Sony 350wsp broadcast camera I've tried a dof calculator but these seem only to work out the dof for 35mm cameras, Also the fact that it's a zoom lens is confusing me , I underhand how hyperfocal works just not quite sure how to get it , any help appreciated :)
