BenQ W1500 Projector – Hardware Tour 3

BENQ W1500 HARDWARE TOUR  PAGE 3:  Lens throw and Lens Shift

BenQ W1500 Lens Throw

The W1500 has twice the zoom range of the lower cost W1070, one of the “extra” features you are paying more for.  The 1.6:1 zoom lens is quite a bit for a DLP projector, whereas 1.1:1 to 1.3:1 is the most common.

BenQ provides a nice chart in their User manual with the throw distances for many sized screens.  We, on the other hand, will provide you with the closest and furthest distances you can place the W1500 projector from a 100″ diagonal 16:9 screen.

From our data, though, you can easily figure out the distances for any sized screen with a simple calculation.

You can place the W1500 (measured from the front of the lens to the 100″ diagonal screen) as close as 7 feet, 8 inches.  At its furthest, the W1500 can be as far back as 12 feet 5 inches.

Now lets’ say you are thinking about a 125″ diagonal screen, multiple those numbers by 1.25 so for that 125″ diagonals screen you would have a working range of about 9 feet 8 inches to 15 feet 7 inches.  See, it’s that easy.

W1500 Lens Shift

As already mentioned, the amount of lens shift provided is minimal, but that said, if it’s got enough for your setup, that’s all you can ask for.  BenQ again provides a chart, but they mention that it may not be accurate.  It seems not to be.

The W1500’s lens shift range allows for the following.  If you are ceiling mounting the center of the lens can be placed anywhere from being almost 6 inches above  the top of the screen surface to about even with the top.

If table mounted, then it would be almost 6 inches below the bottom of the screen, up to even with the bottom of the surface.   That’s based on some quick measurements.  BenQ’s chart indicates only about 2 and 2/3 inches range, whereas we came up with a little over 5 inches.

I’d definitely recommend doing your own lens shift measurements before you mount the projector.

BTW with this little lens shift, you can’t mount the projector up high on a rear shelf, although, that wasn’t likely anyway, since the zoom lens isn’t telephoto enough to get to a rear wall in many rooms, unless you have a really super-sized screen for the room’s size.


Bottom line:  While there is some lens shift, and it should definitely allow an installation to be fine tuned easily, remember that it’s a few inches of vertical range.  By comparison, LCD projectors with lens shift like the two Panasonic projectors or the Epson 8350, 4030, and 5030UB, can be placed anywhere from over two feet below to over two feet above, the bottom, and top of your screen.
