Compare Projectors – InFocus SP8602 vs. JVC DLA-RS15 6

Bottom Line in terms of image quality

Where it not for the great JVC blacks – without a dynamic iris, I’d probably pick the InFocus overall, as a much superior projector. But, in the wonderful world of dark scenes, there’s still a significant advantage to achieving great blacks without being forced to suffer the side effects of a dynamic iris. I appreciated my own RS20’s lack of a dynamic iris, frequently, when switching back and forth between it, and the InFocus SP8602 projector.

I should also mention that when I awarded the InFocus, the Best In Class – Runner-up, that was taking InFocus’es word (that I “forced out of them”) that they would improve the dynamic iris action significantly, and quickly. (I took their word because, past experience with multiple manufacturers on this type of thing, has yet to dissapoint me with a broken promise.

And the good news is that last week I was able to install (easy) the new firmware (easy to download too), with the iris action upgrade. The SP8602 still doesn’t have the best iris action around, but it is much improved and I’d say fairly typical of projectors with acceptable iris action.

JVC RS15 vs. SP8602 Projector Performance

Projector Brightness

Depending on how you mount / position, the SP8602, it can be anywhere from bright to very bright among the competition. Certainly, at its worst, it’s as bright, in best mode, as the JVC. From our own measurements: 785 lumens for the InFocus in “best” mode, at mid point zoom, lens at 0 offset. With the same settings (mid-point, 0), the RS15 clocked in at 657. In brightest mode, no contest – InFocus 1110 lumens vs. JVC’s 746 lumens.

Further, if you have the ceiling height, and can mount the InFocus at its maximum lens offset, (for a 100″ screen, the center of lens about 15″ above the top of the screen, you pick up about an extra 18% more lumens. That translates to about 930 and almost 1300 lumens. And all that is with Brilliant Color off. Turn it on and you get about an additional 35%. But, InFocus’es Brilliant Color, while pretty good, is definitely not as natural looking as with it off (which they call “Normal” – vs. “High” being on).

In other words, the InFocus, is always the brighter projector, and if you bring every factor into play, in brightest mode, it can be a full 60% brighter than the JVC!

What about sharpness

No contest. I’m not convinced that the SP8602 is as razor sharp as the older IN83, in fact I’m pretty certain it’s not. Still, it’s a pretty sharp DLP, and that makes it sharper than any LCoS projector I’ve seen, except maybe an RS35 with perfect pixel alignment.

No question that the RS15 looks softer than the InFocus – it’s not great at all, on movies, but on pure HD digital content, the InFocus adds that extra appearance of sharpness that I really find to be an improvement. I’ve always complained (slightly) that I wish my own JVC was a bit sharper, primarily for all that HDTV sports and digital Discovery-HD and similar content.
