Hi everyone:
I've been out of the loop here since 2006, so I'm hoping to use the expertise in this forum to help choose my next projector. In 2006, I utilized my 12' X 24' room to set up a kodak 333 (which is a modified infocus 777 3 chip DLP) to project onto a 133" stewart firehawk screen. The kodak 333 is a 720p, 3000+ lumen light cannon, roughly 5000:1 contrast. I had the 1.8-2.4X lens at a 20' throw distance. The picture was phenomenal, I was in awe every time I watched something, even 7 years after I purchased the system.

I've just moved to a new home which isn't quite as projector friendly. Due to a lower ceiling and the presence of ductwork, the ideal position for a projector is backing against one of the ducts which is 9' from the screen (I can still use the 133" firehawk). When you account for the approximate 2' length of the projector, that leaves about a 7' throw distance, which means with a 10' wide screen you need a lens .7X ? Is this a common setup, or is it even possible? I'm looking to spend approximately $5K on a new projector, any suggestions as to what projector would be best bang for the buck for my situation?Would the picture quality be better than my old system? If this setup isn't possible, then I'll have to settle for the 80" aquos or something similar, but I would much prefer the projector if possible. Thanks in advance for any suggestions!

You might be able to, the DPI Cine 1000 has a 0.73x lens option. I'd assume other machines that share it's lineage (Runco LS5, etc) would as well. There may be others, but you're going to be somewhat limited with that throw.

He knows. I already sent him a PM with three projectors that might work for him. smile.gif The DPI Cine 1000 LED was one of them.

The op stated "I'm looking to spend approximately $5K on a new projector" Does the DPI Cine 1000 sell for $5000?

Thanks for the responses!
What is the average lens ratio of most of the projectors that are out there? Obviously .7 is very low, I'd assume 2.4 is pretty high. What is the 'sweet spot'?

There is never a sweet spot but there are positions, basically shortest and longest throw where brightness at short and contrast at long throw can be maximized. Going halfway pretty much gives one the worst case for both.

No. I am not aware of any 1080P HT projector that has selectable lens, so that you can get a throw ratio in the 0.7 range. So rather than let him hear crickets for a response, I listed projectors that can do what he asked. It is up to the poster to determine if he wants to raise his budget or do something else.

I'd guess, most common throws fall in roughly the 1.5 to 2.2 or so range.

He could go much cheaper with the Benq w1080st... 1080p and 3d, but notas refined as a 3-chipper... I'd not call it a home theater projector, but cheap enough he might want to give it a try and may even keep it just for 3d and use a big ol' panel for 2d

Good suggestion. About 6'-7" for a 133" diagonal 16:9 image. Agree, I would not really classify this as an HT projector, but it does work.

Will the .73x lens work on an LS-1/3/5? Certainly the LS-1 with lens should come in under 5k, and if no care for 3d is a much nicer image than the benq.

Runco doesn't technically sell that lens for these projectors so you'd have to buy it through DP or another manufacturer, and swap the aesthetic chassis that's around the lens out. This lens offers no zoom so placement needs to be exact. This is probably why they dont off that lens option as VERY few people would actually want it.

Any idea on rough cost... if reasonable, might be interested in one myself... IF the quality is near that of the standard lens.

I know the short throw (1.56-1.86) lens has an MSRP of $1000 through Runco dealers. Being that this is a less complex lens it should be cheaper than that.
