Took out my new CineVista last night and fired up the 8350 for a rough test (aka balancing the lens on foam blocks and projecting on the unfinished screenwall). The picture looks huge - there's definitely a fun immersion factor with scope.
No vignetting with the full zoom I need. At a 2.5x height throw ratio, the pincushion is pretty atrocious - no surprise there - although with video content and proper masking I can see how even this level of distortion effectively disappears in a real-world viewing context. There is noticeable CA fringing at the far edges (no electronic correction on the 8350), although the middle half is laudably sharp. Fine for movies and FPS games, not so much for web browsing and test patterns.
I'm glad I decided to go with a curved screen, which will hopefully go some way towards correcting the worst of the pincushion.
I don't think the CV will satisfy demanding users, but for what it is - an entry level product for folks like me just getting started with this level of imaging and either unable or unwilling to zoom, I think it's a very nice option to have.
