Title: Panamorph Paladin DCR Lens
Post by: AVSCraig on March 20, 2018, 01:20:31 PM
I'm going to document my experiments with the fairly new Panamorph Paladin DCR Lens, with my JVC RS4500 projector and Lumagen Radiance Pro. video processor in this thread ( and anyone else that owns one - feel free to chime in ).

The lens and the U bracket -

So I had 4 people over for a Paladin DCR demonstration today. We watched the first couple of chapters of GOTG2, Star Trek and some of Passengers ( all on 4K Blu-ray ). Everyone preferred the picture with the lens in place. Not only was the picture brighter over all, the extra 2.5 million pixels get the picture more detail and one person thought more depth at times. The opening of Star Trek in particular showed more detail and nuances in the picture. Anyway, it's fun to get other people in to give opinions. Fun day !

In my setup I get 28% more lux with the lens than without, using a light meter and a 100IRE SDR test pattern.

Correction - going from 3840 zooming to 4096 using the full panel with the lens, it's slightly more than a 38% lumen increase, as measured with my Sper Scientific light meter !

No, you would only use a curved screen with a horizontal expansion lens and a throw ratio under 2.0.

I re - measured lumens tonight, using the Chromapure 100IRE test pattern and my Sper Scientific 840020C Lux  Light Meter. No lens, zoomed onto my 2.35:1 screen, mid laser - 288 lux. With lens, Lumagen scaling to 4096 x 2160, mid laser - 400 lux. That's about 38% more lumens !

Interesting reading Craig... My last attempt with an anamorphic lens, a ISCO III 1.33x, made me finally decide on overshooting being the more preferred method. The chromatic aberration, light bleed / reduced contrast, reduced sharpness and only what I was able to measure out as an 18% increase in light output made that conclusion quite clear to me. I do get, however, some installs simply needs a lens to get a sufficient throw, and 18% is indeed a nice boost too, so I completely understand that others might come to another conclusion than me... :)

However, this vertical compression lens seems to be producing quite a significant boost, 30-40% is kinda amazing and in these HDR times more important than ever. I mean, are you not seeing any of the "normal" artefacts introduced by this additional optical element mentioned above? Is the overall sharpness seemingly better?

Your observations had me a bit intrigued, might even want to order one and test it out for myself.... ;)

There is no loss in sharpness that I can see. It looks just as sharp but the higher pixel density makes the small details easier to see - also the boost in brightness helps too. I also don't see any reduction in contrast. All the negatives you mentioned about A lenses are the exact reasons I haven't used one in at least 10 years. I experienced all those negatives, which in my mind offset the positives. Then some clever person sent me this lens to try. I'm lucky wine shops don't send me expensive wine to try - I'd be in big trouble ! Anyway, all I can say is this lens is unlike any that I've used.  The brightness boost with 4K HDR is so easy to see on a movie like Guardian of the Galaxy 2, there isn't any comparison. Remember though, the Paladin DCR is specifically for 4096 projectors. That's where you'll get the full 38% brightness increase. A Paladin lens with a 3840 projector will only see about 30% increase.
These particular vertical compression lenses totally flipped my opinion about A lenses 180 degrees. I'm just finishing up a mount to integrate this lens with my projector closet front panel. I'll post some photos tomorrow !

Oh ya, my independent panel of observers that were here for the " lens / no lens " test, begged me to keep the lens. They even offered to pay $ 10.00 every time they watch a movie here to help pay for it ! They could see the difference, and they aren't even home theater nuts !

Title: Re: Panamorph Paladin DCR Lens
Post by: AVSCraig on March 31, 2018, 03:01:35 PM
With 47 foot lamberts, I could probably either close the iris a bit, or run a custom gamma curve that's not as bright but better for mid tones. I haven't even explored the HDR tone mapping in the Lumagen yet - that's next.

Post by: AVSCraig on March 31, 2018, 03:20:05 PM
As far as sharpness, the first thing I looked at was titles / graphics in " Passengers ", which is super sharp overall ( 4K Blu-ray ). All the graphics / titles / writing looked just as sharp as with no lens. Same with GOTG2.

What are you doing for your second screen? Are you swinging the Paladin out of the way and then using lens memory to resize for your 16:9 screen or are you using the Lumagen to resize the image?

It's not really gray - that's Rosco Velour Black paint. It just looks gray - it's hard to photograph. To photograph anything it has to be overexposed, which just makes it appear gray.

Since we would like for more people to try out this new lens so that they can see the benefits, we have set up a so that people can buy the lens, try it out for two weeks and return. You would pay a restocking fee of 10%. This applies to any of Panamorph's lens, not just the DCR. If anyone would like to try out a Panamorph lens, give us a call.

People have asked whether the Paladin lens are plastic or glass. Here's what Shawn Kelly had to say -


Um, just to be perfectly clear (did I say that?) Panamorph lenses are made from high end optical projection glass to higher than typical industry Mil-Spec standards with optimized AR coatings. It is true that they are hybrids of cylindrical and prism technologies which makes them expensive to produce, but they are certainly made completely from glass which is why when we say we've sold tons of lenses its quite literal.

You might call Shawn at Panamorph and ask, since the Paladin lenses are designed to work with flat screens.

Setup Procedure for a Panamorph DCR Lens with a Lumagen Radiance Pro

      The Radiance Pro and Panamorph DCR lens can be used together for any projector that has a native 4096x2160 (4k) output resolution.  A projector with a fixed anamorphic lens such as the DCR will project an image that fills a 2.40 screen aspect ratio. When using the DCR lens to fill a 2.40 screen, the lens provides up to 38% more light output for anamorphic sources verses no lens in place.  Use the following procedure to configure the Radiance Pro for a system that includes a 4096x2160 projector with a Panamorph DCR lens and a 2.40 aspect ratio screen.

1.    Set the output aspect ratio by pressing: MENU, Output, Styles, [Style], Aspect Ratio, OK, Single output aspect, OK, 240, OK Note “Style 0” is used for all sources at factory defaults, but this can be changed.
2.    Set the output resolution to 4096x2160. Press MENU → Output Setup→ Ok. This will display the Input Conditions and Output Selections .Press “OK” again to display the Video Output Select Menu. Highlight the ‘2D’ or ‘3D’ row and press “Ok” to edit. Next highlight the input that you want to edit. Scroll over to mode under video output selection and use the up or down keys to select 4096x2160, 24 or 60Hz. While in this mode, you can press the number “4” button which then selects ‘All’. This allows you to apply the 4096x2160 output resolution to all of your inputs at once.
3.    Set the projector to its default 16:9 mode.
4.    Set all the video sources to widescreen 16:9 output.
5.    Press the appropriate input aspect ratio button on the Lumagen remote that matches the aspect of the video source. Note that for a 2.40 source press the two button sequence of 2.35 and then ALT to select input aspect as 2.40.
6.    To horizontally stretch a 16:9 image to fill the 2.40 screen, press “16:9” and then “NLS.”
7.    Display a 2.39 movie .Use your projector zoom to get the source to just fit the width of the screen. You may have some small over scan top and bottom after doing this. If you wish, use the Radiance output “Shrink” to reduce the top and bottom to have the desired over scan: MENU, Output, Styles, [Style], Mask/Shrink, Shrink. Start with a half percent value and slowly move up
8.    Make sure to do a Save (MENU, up-arrow, OK, OK, OK) after any changes or they will be lost going to Stand-by, or if wall-power is removed.

Thanks!!!

... and I do this *after* installing the lens, right?

The Paladin DCR is a great A lens for my Z1 - I only need to get my head around the adjustment process... But Shawn Kelly is very helpful here!

Yes, but have to make sure projector is first set up with the screen, so that everything is lined up correctly. Then add the lens.

I sure did so. But I noticed some issues with the white alignment grid in the Z1 menu, where blue and red needs to match the white lines' position. Here, the lens adds some mismatch. But Shawn told me where to start to get rid of those issues...

Is there the perfect hight and tilt angle for the Paladin DCR, that minimizes barrel distortion AND preserves the perfect grid allignment?
I've been experimenting a lot with both but couldn't find the perfect solution yet... Anyone?

Did you use the installation guide?

Sure I did. Thoroughly.
But I either get better geometry OR better panel alignment. Not both. So I was wondering...

What is your throw ratio ? Are you at minimum throw distance like I am ?

With 1.82:1 I should be fine, I guess...

Ceiling mounted ? Make sure the " Panamorph " is facing down ( there is a right side up and an upside down ). 
You may need to try raising / lowering the lens, and I'd try mounting it as close to the projector lens as possible. I settled on a perfectly straight bottom of the picture, and a little barrel distortion on the sides. I'm at minimum throw. You'll need to play with it a bit .

Don't get me wrong, I'm pretty happy with the result that I've found after like two full days of "playing" with adjusting the lens position. And I have almost no barrel distortion now.
And I found that keeping the hight of the Paladin as centered to the projector's beam output (not the lens itself) as possible and as little tilt (in relation to the center of the beam itself) as possible is a good start.
But there might be other ideas in this group so I asked...

A little trick that you can use for DCR lens setup. Slide a piece of copy paper between the projector lens and the DCR lens. That way, you can look into the DCR lens and see exactly where the projector image is hitting on the DCR lens and adjust the DCR lens so that the image is centered on the back glass. Then adjust horizontal angle so that image is centered. Then it is a simple matter of adjusting vertical angle of the lens. I would then go back and check with paper that you are still centered and adjust if needed.

Of course you do not do any of this until after the image without DCR lens is squared up with the screen properly.

That sounds like a pretty good idea, thanks! I'll give it a try first thing tonight!
