Panamorph power buy..anyone? - Page 3  

post #61 of 108
Unfortunately I don't think my setup is ideal for this lens. I emailed Jason yesterday about my dilemma but I am sure he is a real busy guy so maybe Monkey Man or some other Panamorph gurus can chime in here to help me out.

My throw ratio is around 1.5...170" throw distance, 116" screen width. I think I was a little confused on how this particular model worked...ie. I was under the impression it was a constant height, but I see now...or I think I see it is for constant width.

Looking for some input to see if I can find a workaround for this lens on my system.

If this is successful and a drammatic improvement this may change my viewing habits off cable TV and back to OTA and watching movies on DVDs versus HD cable

Currently using a Sharp PG A10x that automatically shifts to stretch (1024*576) on an HD signal (what little credit these manufacturers give us - there isn't even an overide option).

So I will use MyHD card and full mode (1024*768) for OTA HD and DVDs (maybe TheaterTek as well but I have been unsuccessful reinstalling with with new keys).

This actually could end up saving me money to get a better picture.

(Cable/internet/HD movies =$145; versus DSL $50, Netflix $30 - I can't watch HD cable movies with the Panamoph anyway)

I also want the slide as don't want any "softening" for computer display and also want 4*3 for digital photos; camcorder some DVDs and other computer apps.

Bump. I am still trying to get some answers.... Please Help

The panamorph is intended to 2.35:1 material, not 4:3 or 16x9. It is most effective with a 1.65 or greater throw ratio.
post #66 of 108
My understanding is that it takes a 4:3 image and compresses it to a 16:9 and therefore helps all widescreen movies. Where does it say that it is only intended for 2.35:1? I was just wondering if there is a way to take full advantage of a 4:3 screen and use the Panamorph to improve both 4:3 DVD's and Cable TV with more pixels somehow by taking advantage of the Native Mode (4:3 image with letterbars on a WideScreen) on the X1. I currently own a 4:3 Electric Targa Draper screen and was wondering how much the picture would improve and what types of material would it improve? I was wondering if it is comparable to just getting a Native XGA projector or not if you currently own a SVGA projector like the X1.

After you read the link you will be better informed - but I certainly am only getting it to transform my 4*3 output into 16*9 - However I have an XGA projector.

So in my case I will take 1024*768 pixels in a 4*3 format and have the lens focus it into a 16*9 image with the same width. This will also minimize my light spill situation when watching wide screen material


This contrasts with what the projector will do on its own - take an HD signal and display in in 16*9 mode using same horizontal pixels (1024) but only 576 vertical. So I will get extra pixels for more picture information and also extra brightness that should compensate for light loss through the lens.

In order to do this I need a source that will output widescreen material in a full (4*3) mode - (think tall thin people) if the lens was slid out of the beam.

You should have the similar situation with an SVGA 4*3 - just the number of pixels in the equation is changing. You will get 800*600 for your DVD example - this doesn't equal horizontally what I get now with an XGA (as noted above 1024) but exceeds it in the vertical (576). I have heard that the horizontal resolution is the real discriminator of HD so the closer you can get to 1920 the better - the panamorph doesn't change horizontal and somewhere around 1300 or so is where you could consider it HD and not high resolution)

I don't know exactly how many vertical pixels you currently get with widescreen but imagine it is around the same ratio reduction I have (600x 576/768= 450)

Well I bit and sent my email to Jason. I was always hesitant to buy a liquid filled one for fear of leaks, but if this one is solid I imagine I will use it for a long time. I've seen my X1 with an anamorphic lens before and that was said to have a focus defect (I also think it was liquid, but I don't remember for sure). I was still impressed, so I think I will like what we get with this new one.
post #70 of 108
Because there are lots of us that own a Z2, I thought the following information might be beneficial for someone else who might share my concnerns.

What follows is an e-mail I sent to Jason regarding mounting the new Panamorph in front of a table-mounted Z2.

To: jason@avscience.com

Subject: Panamorph

Jason,

I tried to send the following message to Panamorph directly (Contact@visr.com) concerning the powerbuy for the low-cost Panamorph lens, but it came back as undeliverable. So maybe you can answer some of these questions for me.

I'm interested in purchasing one of these units, but my particular setup (and the "non-refundable" aspect of the offer) has me somewhat concerned. Here's my dilemma: I'm a little confused as to how the Panamorph will sit in front of a table-mounted projector, namely my Z2. I've seen a picture of the PSO-U100 with the optional slide rail (http://www.panamorph.com/Acrobat/PanamorphGuide.pdf), and from that picture I made a couple of assumptions:
1) the lens is height-adjustable via the black thumbscrews on the sides and
2) it can be tilted, with the thumbscrews being the axis of rotation

Are either of these assumptions is correct? If it is height-adjustable, what's the distance from its lowest setting to its highest? Will the new lens feature the same vertical and rotational adjustment?

The Z2 has a flip-down front cover that sticks out 1½ inches in front of the projector once the front cover is lowered. I'm wondering if this is going to be a problem while trying to set the Panamorph in front of the projector lens. Will the new lens have an attached base to allow for table mounting? If so, will it be narrow enough to sit on the cover? Conversely, if the Panamorph is sitting 1½ inches in front of the projector lens, is the width of the beam entering the Panamorph narrower than the 1½" max width requirement? From what I've read, the Panamorph needs to be as flush against the projector lens as possible.


Any assistance you can provide would be helpful, as I want to take advantage of this offer. Thanks.
James




Jason’s Response:
Sure thing.

1. Yes the lens is adjustable for height, tilt and side to side.
2. Yes.

You should be able to mount it in front of the flip down panel, and then the lens is offset a bit so it will be close enough to the lens of the projector. I don't think you'll have any problems.

Let me know.

Thanks!

Thanks James for fielding those questions to Jason.

That's great if indeed the U10 can sit on the ledge that the front cover makes. That will make mounting easier for table mounting... my Z2 actually sits on a pull out TV shelf, so that would work for me.

I think at this point my only concern with the Z2 is with a upscaling DVI DVD player. With 720P DVI connection the Z2 gives you no ability to change zoom factors... it's locked. So, you'll need to use a HTPC or external scaler if you are using DVI. Nothing's ever easy.
post #72 of 108
I'm not sure how narrow this "ledge" is. If it is a part of the projector I would have 2 concerns.

1. The lens is big.
2. The lens is heavy.

I do not think that if this flip down this is meant to be used as a shelf it should be.

I don't know exactly but this this has got to be 6"x6"x6" and a few pounds.
post #73 of 108
The cover ledge is 1.5" deep.

It certainly would be nice to know a little more information about the U10, specifically it's measurements and weight. The U100 is listed about 4"x3.75"x4". If the U10 is similar, then there is no way that the Z2 can sit on the 1.5" ledge, as it would fall forward.

I'm wonder if Jason knows how large the Z2's ledge was either before he responded. Perhaps the U10 is much smaller than the U100 and therefore can sit on the ledge?

As for the weight, the U100 is 27oz/766gms. It might be a bit heavy for the ledge.
post #74 of 108
I interpreted Jason's response - "in front of the flip down panel" - to mean that the Panamorph is not sitting on the ledge, but on the table that the projector sits on. Not "on top of the flip down panel".

But he goes on to say that "the lens is offset a bit so it will be close enough to the lens of the projector", which again seems to suggest (to me) that even though the base of the Panamorph housing is 1.5" from the projector's lens, the Panamorph lens itself is closer to the projector's lens.

I think we need some clarification on this. I'll give Jason a holler and see what he says.

James

Okay, I sent Jason another e-mail asking for clarification of the "on the ledge" vs "in front of the ledge" issue. My message and his response are as follows:


Jason,

I posted my e-mail and your reply on the "Panamorph power buy...anyone?" thread (see post #70 of this thread). I thought there might be someone else out there who had the same concerns as I did and that your response would be helpful. While your answers seemed pretty clear to me, they caused some confusion for others...which, in turn, caused confusion for me!

When you said, "you should be able to mount it in front of the flip down panel", did you mean that the Panamorph sits on the table that the projector sits on, or on top of the 1½" ledge?

When you mentioned that "the lens was offset a bit", did you mean that with the base of the Panamorph lens sitting 1½" from the projector's lens (in front of the flip down panel / on the table, not on the ledge), that the Panamorph lens itself is protruding backwards towards the projector's lens?


Sorry you have to spell it out (be as...umm...monosyllabic as you want); some of us are a little slow on the uptake...and don't want to part with $695 non-refundable dollars.

James


Jason's Response:
Sure thing. The lens mount should sit on the table in front of the panel. Then it has a slight offset from the mount which would then overhang that same panel and get the lens closer to the projector lens.

It kind of looks like the attachment.

Thanks!

Hey---- thanks for calling me slow. :p

That makes sense. Unfortunately, I have no table to mount it on, so I'll have to do some additional thinking.
post #77 of 108
Hi everyone.

I am looking at an anamorphic lens as an investment, and if it means spending a little more for durability, I will do it. On the other hand, if the design of this sight-unseen value model seems sturdy enough I will jump in.

However, I am worried about wear and tear on this plastic model. Specifically, I am referring to the rail system and the fork which holds the lens. Does anyone know if these will also be made of plastic--or will they be milled aluminum? The description seems to say that the housing of the lens itself is plastic, but makes no mention of the fork or rail (just a "simple mounting bracket"). I am a little concerned because I am envisioning years of sliding the lens in and out of the beam, and over time the rail system and any interfaces between moving parts getting stripped. Furthermore, what about the thumbscrews--do the threads interdigitate with the plastic housing (if so, the plastic "female" threads in the housing could be stripped over time), or is there a metal female insert that the thumbscrews feed into?

Any info?

The rail and fork system are aluminum.

I STRONGLY recommend (after getting mine and seeing what happens if you ignore it) that you make sure your throw ratio at least meets their required 1.65. The longer your ratio, the less warping you will see.

A few post in this thread have mentioned that the panamorph compresses the image Vertically????? I was always under the impression that the panamorph stretched the image Horizontally keeping a constant height setup? Can someone confirm which it is, and which lens does do a constant height setup? Also with the power buy panamorph being made out of plastic would there be problems with warping from heat?

Cheers,
Rob

Rob, the Panamorph compresses the image vertically keeping a constant width. The IISCO lens does what you have described - a constant height setup. Since the Panamorph only compresses light and all the heat is in the projector (bulb is the culprit) I think warping is a non-issue.

John:)
post #82 of 108
The panamorph DEFINATELY comresses the image. Read the pdf linked earlier. There is a little table with all the screen/aspect combinations. You will see that they all are constant width.

The ISCO is the lens that stretches.
post #83 of 108
Also worth noting that, as expensive as the Panamorph is, the ISCO is even more expensive.

Good LORD... see the new Panamorph powerbuy price stickied at the top of the forum. It makes me want to cry when I think of what I spent...

Seconded. I still got a good deal on mine. I'm not sure if this buy is for the same model I got. Mine is with the metal housing, I think this is a plastic housing, but for $200, I could have lived with the plastic, believe me!

Apparently not! It looks like plastic.
post #87 of 108
I just spoke with Jason. The rail is metal (didn't ask about the fork).
post #88 of 108
I gotta say the new price is certainly tempting me. It's still a lot of money, but given what others have paid and the fact that it's a fairly upgrade-proof investment...I'm considering this new lens buy.

At this new price if it doen't work out you can ebay it and make money after the power buy.
post #90 of 108

Jason just emailed me to let me know that they were processing cards. He said the first orders are being made at this moment and it should just be a matter of weeks until the lens arrives at my house!!!

All I have to say is,"the squeaky wheel gets the oil".
