With a current typical street price over $3000 (for the NTU), the F100NTU isn't for those with weak budgets. It is, however, a 3200 lumen LCD projector, and that's enough horsepower for bright conference rooms, training rooms, etc., and has plenty of power for large multi-purpose rooms, hotel ballrooms, and small auditoriums, with sufficient lighting control to keep ambient light to "moderate".
The F100 series projectors are a bit too large to be considered portable (and too heavy at almost 14 pounds), unlike the similarly bright, but smaller Epson Powerlite 1815 projector recently reviewed.
On the other hand, the F100's have some extra features that give them a big advantage over the Epson's for fixed installations, notably, full lens shift, and an automatic filter system, that drastically cuts down on maintenance, and the associated labor costs of frequently cleaning filters. Panasonic calls their system ARF - Automatic Rolling Filter. I works like it sounds. I'll discuss this in greater detail below.
