KraGorn Active Member. Short throw means a short distance between projector and screen .. say 1-1.75 times screen width as a rough guide, long throw is the converse being 1.75+. That means the HS51 is certainly 'short', from the spec:  Short Throw Lens (100 < 3m), ie. you could fill a 100 diagonal 16:9 screen (7'+ screen width) from less than 9'. I don't know the Sony but generally I think Lens Shift works at least 1/2 height and/or 1/2 width depending on what it's capable of.
The mathematical calculation of this effect is called âthrow ratio.â Technically speaking, âThrow ratioâ is an equation that explains the distance from projector to screen compared to the screen size. For example, a standard projector might have a 1.5:1 throw ratio. So, to get a 60-inch image; the projector would have to be 7.5 feet back from the screen. Or, approximately 1.5â back for every 1â of screen. Any projector will have this ratio listed in the general specifications.
