This is a forum for people who like to project Constant Image Height movies. As far as I can see there's no requirement for them to be cameramen or otherwise involved in the film industry, or to have lugged Mac Pros around on their back...

Quote:Mind you, a cheap manual sled arrangement using draw runners would work just fine. You don't get it. Using a sled with a vertical compression lens results in constant width, not constant height. That is why the manufacturer...

Quote:We have been arguing over the lower end pieces in the Panamorph lineup, which I have acknowledged time and again have some compromises in comparison to our high end lens systems. So it's the "crispest and brightest on the planet"...

An un-corrected system that exhibits "only" a 1 pixel(!) color smear, and that has astigmatism built-in cannot possibly be as good as a color corrected system with astigmatism control. Color correction in any system, particularly a...

Quote:The FVX200, when used within its specified throw range and distance, should actually be the crispest and brightest anamorphic lens on the planet regardless of price point, mostly due to the fact that there are only two elements...

Throw ratio is Throw/16x9_Width or Throw * .5625/H Based on a 100" diagonal 2.35:1 screen ... 2.35 Screen 39.2 = height 92.0 = width 100.0 = diagonal (we knew that already!) 16x9 Screen (based on height) 69.6 = 16x9 width So divide...

Two questions first: 1. Do you mean "How do I calculate Throw RATIO"? 2. Is your 2.35 screen 100" WIDE or DIAGONAL?

Quote:I figured as much. I did buy the astigmatism correction add-on, but I haven't found it has helped as much as I would have thought, especially at this throw. There are two main focal planes you need to consider when using prism...

Quote:Is this normal with all prism lenses, or do I just need to ante up and get a better lens? "Yes", and "Yes". Prism lenses of the HTB caliber have no astigmatism correction. So you can get the image sort of focused in the center,...

Quote:I seem to remember that there is a significant difference in the lumens depending on which projector lens I use. Would the longer throw t3 lens allow more light or less light than the medium throw t2? Aren't longer throw lenses...
