Yes, this year, every projector in this mid-priced class offers lens shift! All of them have at least a 1.5:1 zoom ratio as well. In other words every projector we reviewed in this price range had at least good placement flexibility. The most signficant difference between “Greatest” and “Good” placement flexibility is that most of the “good” ones may not work rear shelf mounted, if your room is moderately deep, or your screen relatively small for the room size. those with 2:1 zooms normally can be shelf mounted in all but very unusual (read very deep) rooms, even these “greatest” projectors won’t be rear shelf mountable (with a 100″ diagonal screen) in rooms deeper than about 22 feet.
All projectors in this class have lens shift as well! This year every projector without lens shift, sells for under $2000. Last year, we had some projectors without lens shift, in all three price classes. What has changed? Primarily the DLP projector manufacturers have been getting tired of losing sales to the LCD camp, because of placement flexibility.
Ceiling Height Issues: These projectors are less likely to work in your home theater if your ceiling height is low, or if ceiling height is average, but screen size is rather large. This is due to a lack of lens shift, combined with a signficant amount of fixed lens offset, that requires them to be mounted well above the top of your screen. All of these must be mounted at least 7.5 inches (measured from the center of the lens) and up to 16.5 inches above the top of the screen.
