OK, Ruby is sitting in the box upstairs, drywall is stacked on a pile in the basement . . . and I am continuing to wait patiently (ok, not so patiently) for all of this construction to end and the building of my HT to begin.
So, I have been reading as much as I can about add-on lenses for the PJs and the Ruby specifically, but I am not sure I can discern what situation warrants the addition of a lens -- I am looking to mount the Ruby at between 12 - 15 feet for a 100" Stewart Firehawk screen. What should I look for to determine whether I should be in the market for an add-on lens? Any help for a new AVSer is appreciated. Thanks in advance.
