The VW915ES offers motorized focus and zoom as well as plenty of horizontal and vertical lens shift.
Lens Shift Range: +85/-80% Vertical and +/-33% Horizontal
When projecting a 100″ diagonal 16:9 image, 80% of the image height is approximately 39 inches while 85% of its width is about 41 ½ inches. This means the bottom of the projected image can be shifted down 39” or you can shift the top of the image up 41½ inches.
While +/- 33% horizontal shift means you can shift a 100” image to the left or right about 28 inches. Just remember, like most projectors, the more horizontal shift you use, the less vertical adjustment you will have available.
Having a large amount of zoom and shift capability makes installation a breeze especially when you are trying to replace an older unit that was previously fixed mounted.
For even more flexibility, you can save multiple configurations thanks to the Lens Memory function (accessible from the menus, or the Position button on the remote control).
Sony does have two quality levels of optics. The VPL-VW915ES uses the standard lens, which is still impressive, especially when compared to the optics found on many lower-cost 4K DLP projectors (selling for 1/10th this Sony’s price).
The ARC-F (All Range Crisp Focus) lens is Sony’s premium projector lens and it is used in Sony’s more expensive models like the VW995ES and the VW5000ES. One of the reasons why the VW995ES is $15,000 more than the VW915ES is that ultra-high-quality optics are very expensive, but they do make images sharper.
The ARC-F ensures outstanding focus was excellent across the entire screen and significantly reduce chromatic aberration (color fringing). If you are projecting on to a massive screen, it is worth the premium to be able to extract every ounce of detail for the 4K SXRD panels.
Like Sony’s other 4K home theater projectors, the VPL-VW915ES doesn’t sport a lot of inputs and connectors. There are just a pair of 18Gbps HDMI 2.0b/HDCP 2.2 Compatible which allows playback of 4K@60 HDP content. This is fine since most projectors at this price point will be utilized in a full-blown home theater system. All the sources (cable box, media player, game system, etc.) will probably be connected to an AV Receiver feed video to the VW915ES via a single HDMI anyway.
