If I focus the upper left to be razor sharp, the lower right will still be in focus but not razor sharp. It's still OK, certainly not dull or blurry, but it's not exactly the same sharpness sharp as the upper left. If I was to compare, I'd say upper left is 100% sharp and lower right is 85% or something like that. Something I can live with and probably a drawback of a projector in this price range? Not sure. Anyway, if they're supposed to match, though, like 100% sharpness in all four corners, I might RMA, but then that might be being petty, I don't know.
Side note: I'm using max zoom and adjusted the focus as best as I could.
Yes, you've got the focusing issue. When you say max zoom do you mean the picture is at its largest? That is the way to see the issue at its worst. Good luck. I'd probably return via warranty it to Optoma and use RMA so they switch it out with a new (and, hopefully, fixed) lens.
I'm kind of in the same boat, although mine does seem to have a tiny, hair-sized position with the focus knob where the problem can't be seen. I just wonder what will happen if heat causes changes. My PJ is a little more difficult to access for touch-ups.
I hope others chime in here.
P.S.: Like Mitgsx I think this is a great budget PJ. Contrast, Blacks, Color, Sharpness and really good 3D.
