The more sharp a lens is with least artifacts, the more expensive it is. And shift significantly raises the price as well. You could have a lens in a $1299 pj that does a wide shift range but it will likely be a junky lens compared to a similarly priced lens without shift.
Since lens is one thing DLP manufacturers can control to increase sharpness and contrast whole reducing artifacts, it's wise to invest in an excellent lens, especially when a weak lens with blurriness and artifacts will spoil the 4k effect. And an excellent lens with shift is a lot more expensive than one without.
Just a few thoughts...
The JVC RS420 (with lens shift) has a good lens by most standards and it has a $3,999.95 MSRP and very close price to the Vivitek. We're seeing much higher priced DLPs still with no lens shift (or just a tad of vertical i.e, 10%). I used to own the LS10000 and it still had a good lens even if not as good as JVC's, but I bet it's on par with these cheap "4K" DLPs. I suspect it's more of a DLP market base with primary users having 16x9 screens (who do a lot of gaming & TV versus mostly scope films), and/or maybe something where there is some kind of issue (or more difficulty) with the lens shift implementation as we've seen very little lens shifting for years in most DLPs. I recall Sharp made a DLP with shift and lens memories.
And do we know how "excellent" these lenses actually are in these relatively low cost "4K" DLPs? As we all know, a good lens is not cheap whether we are talking cameras, telescopes, or anything else.
However, I do think DLP technology actually allows manufacturers to get away with a lesser lens quality compared to LCD variants in order to maintain good sharpness. I think DLP has some inherent advantages here (and uniformity that matter). Heck, I saw a $750 Benq HT2050 and was impressed with its natural sharpness. It sort of shocked me to be honest. I thought for the money
, the lens was pretty good although there was more chromatic aberration with the lens than I've ever seen on the LS10000 or any JVC at $4000+.
