UH 380 and HT5000

post #1 of 17
Thread Starter 
Last night, I finished the installation of the new Sim2 HT5000. When I had the pj placed and aligned and focused on the screen (13' wide) I then placed the Panamorph in front and the focus went out. No matter what I tried, the image wouldn't focus. I had the Panamorph mounted previously with the Sim2 300E without any problems so I feel confident that the UH 380 is fine. I was wondering if the large lens on the HT5000 would be the problem as it is larger that the intial lens on the Panamorph. What options do I have for a lens?

BTW, the throw distance is 31'

Thanks

Can you refocus the HT5000? It might be worth PMing Shawn Kelly to see what he thinks if that doesn't fix it..

Mitch what lens are you using with the 5000. Are you near the extreme end of the large image zoom ?
Just for test purpose can you zoom the Sim as small as possible to see if you are able to get a clean focus on the screen even though the image will not fill the screen, This will confirm if its an aperture issue.

Just a note for everyone, the 5000 does not have a reset lens like the Sim 1 chip DLPs.

I am using the L4 lens. I am at a throw ratio of around 3.3 and I am in the middle of the zoom range. I will try zooming in and out to see if that makes it better. I also called Sim2 and was told it is probably a throw distance issue with the Panamorph lens. I am testing an Isco lens tomorrow.

What is the designation of the standard lens ?

I know this probably may not help, but i had to talk to Sim last week, one of the subjects being scoping the 5k. I ended up speaking to thier senior tech guy in UK. He said that ISCO were the only lenses they recommend and that they had tested them with all thier PJs and had no issues outside throw considerations.
If you have time could you give us your opinion of the 5k in the hi-end pj forum?

Sim2 here in the UK only seem to use ISCO III lenses at their demos, and they're the best I ever see at any trade shows I attend.

Anything on the CCA ?

I dont know if i replied last time, but i forgot to ask. Did i not give you the marketing dudes number? I know hes posted on here. My building work is nearing completion so im in a similar state to you, in that I need some answers before pulling the trigger.

Sorry, you may have given it to me already I need to check.

I'm confused as to the size of your screen. Is it 13' wide in 2.35 aspect or 1.78 aspect? Your lens is appropriate for throw ratios of 2.56-4.16 according to the manual for the HT5000. For a screen width of 13' (in 1.78 AR) this gives distances of 33 to 54 feet, so I'm assuming your screen is 13' wide in 2.35 AR. If that is so, it is 9.3' wide in 1.78AR. If you are 31' away with your pj, you are using it at a throw ratio of 3.3, well within its range.
If this lens worked with your HT300 at the same throw distance, I see no reason it won't work with the HT5000. The only reason I can think of is the lens isn't close enough to the pj resulting in the image as it enters/exits the UH380 exceeds the size afforded by the UH380. Have you perchance increased the gap between lens and pj in mounting the HT5000? This is the only thing I can think of that could cause this to happen. At your throw of 3.3 you should have no problem with image size through the UH380 unless you have an excessive gap between lens and pj.
I hope Shawn Kelly sees this thread and jumps in here.

Mitch, the reason for the focus challenge is the throw distance. The UH380 is corrected for astigmatism in a range at a much shorter distance. Sim2 has been showing the HT5000/UH380 combo with fantastic results and we certainly want you to achieve the same. Consequently, we are currently developing optional astigmatic lens prescriptions for longer and shorter throw distances. This will come in the form of a kit for you to easily modify the lens yourself. Estimated time is about six weeks and pricing has not yet been determined, but I guarantee this will do the trick.

So I guess I will wait for the kit.

I would love to give a writup about the 5000 but I haven't had a chance to calibrate it much (except the basics, done by myself and I'm no ISF expert by any stretch). Once I have it properly calibrated, I will report.

I talked to SIM today and they said that all of the color coordinate adjustments should be able to be accessed.

Cool. I know there is also a software update due next week or week after.

Last night I installed the replacement lens in the UH 380 for the long throw and what a difference. Finally the image is focused! Now to get the color right....

Thank you Shawn, you are a stand up guy.

What would be considered a long throw distance?
