As a matter of fact I strongly advocate such a thing as the budget DLP projector ""lens shift"" is a never ending source of placement confusion, and IMHO to call this 'offset reducer' "lens shift" almost constitutes a euphemism.
In the early 2000's we had plenty of DLP (and still LCD) projectors that used a true
lens shift and enabling their users to put the projectors at almost any level they desire (e.g. Sharp, Marantz etc.)
Why current DLP home theater projectors still feature a basic business application design (i.e. designed for desktop use the projector will project the image higher so that everyone in the boarding room sees the picture without the heads of your table neigbors in the way) is somewhat beyond me.
All which these 'lens shifts' accomplish is to reduce the so-called offset, so that it is possible that the bottom of the projected image (table-mounted) is on the same horizontal level as the projection lens (or the top of the projected image in a ceiling-mount scenario).
^ That's not "lens shift" in the traditional sense but "offset reduction"!
Heck, my Infocus IN76 did this out of the box and if you really had a high ceiling you could always lower the ceiling mount (while in contrast, it's rather impossible to hang the projector higher unless you remove your ceiling...).
With the BenQ HT5550 / W5700 we do finally see a return of true or real lens shift to an affordable DLP projector, but maybe BenQ should highlight that as true lens shift
so that interested consumers understand that this isn't the 'lens shift' we somehow got used to with all those recent 4K DLP projectors...
