The shorter the throw, the brighter the image, the lower the contrast. Conversely, the longer the throw, the dimmer the image, the greater the contrast. In the HDR era, and assuming you would have a Projector with an adjustable iris, I would be inclined to go short throw, to maximize brightness, and potentially close the iris to regain contrast (depending of course on screen size and gain).

This is a tougher question. If you'll eventually have a JVC Projector, their Dynamic Tone Mapping will make a dramatic improvement with HDR content. The Lumagen would improve it further, but DTM covers quite a bit of the gap. In this case, an argument could be made to get the DCR Lens first, as that 38% bump in brightness can't be achieved any other way. As above, your screen size and gain would influence this decision.

With regard to an external video processor, you might want to wait for release and review of the MadVR Envy, which reportedly may exceed the performance of the Lumagen, with regard to HDR performance. Many of us are following this closely, looking for confirmation of initial reports, more thorough analysis when the product ships, etc.

With those questions keep in mind that I am not the type that upgrades high end electronics all the time as I have to generally save for these large purchases hence why I haven’t upgraded the VW1100es yet. The next two upgrades I’m planning for video are the Lens and Lumagen and those will be spread out over a few years most likely. A new PJ will be saved until last after all the DTS-X Pro layout speakers have been installed along with the Altitude32 48 channel upgrade. So planning on sticking with the Sony PJ for quite a while unless a high output laser PJ becomes available for under $5-7k as I’d rather wait and make the upgrade when can afford to spend $15k+ on a quality unit.
If the majority of what you watch is movies, and since perhaps 70-80% or more of this content is scope aspect ratio, then you would likely want a scope screen (assuming your room isn't 'width limited'). But I'm not clear on what you're referring to with regard to 'stretching'. If you're watching 16:9 content on a 2.35:1 or similar screen, there's no way to fill it without either distorting the aspect ratio, or cropping the image. 'Stretch' seems to suggest the aspect ratio change, where people would appear short and fat, for example. Some people might find this acceptable, but many, including myself, would not. Cropping it would chop off 10% of the image top/bottom, which may or may not be problematic.

The DCR Lens and a Projector with appropriate Anamorophic Modes would give you excellent display of scope content, and can also accurately display 16:9 content with the push of a button. There is some loss of pixels and brightness for 16:9 content with the DCR in place, as opposed to zooming in and out for scope vs 16:9, but most of us find this a very acceptable trade-off.

As for what projector, and when, this is a never-ending conundrum. There's always something better around the corner, but at some point, if there is an available product which meets my needs and desires, then that would end the delay for me. That's how I ended up with the NX7 and DCR Lens, and am pretty pleased with it. Nobody knows what future products will bring, but I can see being pretty satisfied with this for a number of years.

Right, basic projector functions. But being that I have a 1.5 gain screen and the Lens will add brightness shouldn’t they offset each other up until a certain distance?

So, maybe just move my current Sony VW1100es back to the optional better aesthetic location to try out its brightness from there and if it’s satisfactory all the merry it will be when the Lens is added. Does that sound about right as far as trying to determine my most optimal setup?

I’ll check that out!

Cropping it would chop off 10% of the image top/bottom, which may or may not be problematic.


The non linear stretch is basically a way of using the Radiance Pro to use a percentage of each, the vertical and horizontal stretching which will end up cropping just a tiny amount off the the horizontal final image so that my scope screen will always be utilized no matter the native aspect. Push of a button will just change the setting if aspect is needed. I think that is how it works. It’s a very clever way of stretching standard HD to fit scope. My room is 18’ wide so I maxed out my vertical screen size proportional to my rows of seating which ended up producing a 13’-4” WIDE length 2.35 scope screen.

I’m not a purist but do not care for the stretched looking image by any means! They look horrible but when I saw this other method of achieving a stretched image in a different way I wouldn’t have known it was being altered unless it wasn’t being presented in a side by side comparison so really like the idea of implementing it. If it doesnt work out then can always go back to regular viewing, no problem.


The DCR Lens and a Projector with appropriate Anamorophic Modes would give you excellent display of scope content, and can also accurately display 16:9 content with the push of a button.

Yes the never ending tech is a problem I have chose not to chase. That’s why I still have my Sony. I purchased it as soon as it was released and that was based on its brightness plus lens quality. It puts out a bright crisp image so no need to upgrade until can get brighter along with JVC level contrast levels at a much cheaper price point than the Sony was. All the other longer term upgrades like lenses and Lumagen are money better spent in my opinion. They will increase the performance of my existing system until the rest of my audio upgrades catch up.


Thanks a bunch!

Mine (RS4500) was calibrated by Craig Rounds with the A-Lens in place.
Definitely want the calibration done with the lens in place. Kris Deering was able to close down the iris, get me the foot lamberts I wanted and better contrast too, due to the increased brightness with the lens in place.

Sure - everything in life is a compromise. The trick is finding one that ticks the most number of boxes that are important to you. But yes, the screen and DCR will compensate to some degree the light lost from moving the projector back. Calculations will help, but real-world measurements would be even better.

Sounds like a reasonable approach. You'll also need to take into consideration throw distance as far as filling your scope screen, with your current, as well as a future, projector. There's also the minimum throw distance of the DCR lens (1.4x screen width) which needs to be considered.

Your 1.5 gain screen might have a minimum throw distance to avoid hotspotting, along with the DCR lens having it's 1.4 minimum throw. Keep those in mind when picking a mounting distance.

FWIW, right now I'm enjoying the JVC NX-7 w/ DTM and the Paladin DCR. Also, I'm not sure I would want to introduce another peripheral in the chain (Lumagen Pro, MadVr Pro), because realistically, the next latest and greatest is always on the horizon, but need to consider it's incremental ROI value. Would I have purchased this combo prior to C-19, I'm uncertain.

I am not knocking those who can afford it, but for me this is currently the best combo, I've experienced in my HT projector existence (~23 yrs). Of course this is dependent on other factors, i.e Media source, Screen, etc. Just my $0.02, and quick thoughts, YMMV of course.

Peace and blessings,

Azeke

Is there no way to show 16:9 content on a 16:9 screen, using the whole 17:9 panel (with the DCR anamorphic lens on)? Can the Lumagen help with scaling to achieve this ?

16:9 content is not going to be displayed using the entire panel without some of the picture being cropped top and bottom on a 16:9 screen. They are different aspect ratios. Unless you are okay with small black bars on the sides. But why discuss 16:9 screens on the DCR lens thread ? Are you going to use two separate screens ( scope and 16:9 ) like I am?

Very interesting - appreciate the link. I watched it, and found another. I wasn't aware of this capability, and do like the idea that you can select how much cropping to do vs how much stretching, where it stretches, etc.

I'd have to play with it myself to draw any firm conclusions, but this approach is better than others I've seen. I can still see the impact of the stretching, but again it is better than I might have expected. No way for me to know if this is something I would use, but that's pretty neat to have that option available. I wonder if the MadVR Envy will be able to do this.

There is, but not with the DCR. The Paladin DCR is designed to use the entire 17:9 projector resolution specifically for the 2.4:1 movie format. To use 4096 x 2160 for 16:9 content would require a specialized anamorphic lens and an additional scaling mode just for that additional ~ 6% increase in pixels.

Because JVC projectors have Panamorph mounting holes integrated you can either mount to the shelf or mount to the projector. I think mount to the projector (ie under the projector in this case since the feet are down) would be easiest since there are only two holes and it helps to line everything up. You will see a diagram in the instructions for how to invert the DCR lens in its bracket.

Problem installing DCR Lens

Hi Folks, working with dealer to install the DCR lens on an NX7. The problem we're seeing is that the lens seems to zoom the picture out and make it so much smaller that we can't make it fit. Ie, it's squeezing the picture size down. We have tried the Anamorphic C and D and it is not widening the image. The throw is about 15'7"

Just to check, the dealer also installed a Panamorph UH480 he had on the truck, and when it place it does indeed stretch the 2.4:1 video to fit the screen. Any suggestions? (We have updated to latest firmware)

The DCR is a vertical compression lens so it works by changing the image height rather than the width to fit a 2.4:1 screen. It is not designed to widen the image like the old lens models. In the instructions you will find the steps for the lens setup. It's important to follow each of those steps before going to the next step. You can certainly request your dealer to contact Panamorph for assistance.

Thanks Shawn. He's verifying the steps, and will give a call in a bit most likely. Appreciate the fast response!
Edit: looks like I didn't do enough research on the throw ratio (which lands at just over 1.16) - so user error.

Hopefully, you have enough room to move back to meet the DCR minimum throw of 1.4. I just barely made it @ 1.4.1.

Peace and blessings,

Technically it's not a problem. Personally, I'm not a fan of NLS, I think it's better to watch with black bars than to distort some parts of the image and cut off some other parts. But I guess it's a matter of taste, so if there's enough demand, it will be pretty easy to implement.

Understood, and thanks.

My initial reaction was much the same as yours, and I don't know that I would use it, if available. I was just curious, and appreciate your reply.

What happens if you don’t quite make it. Example, DCR is too close at 1.30 throw ?

Even @ 1.41.1 I have spillage onto the velvet sides of the screen. I would think you would need to either, move your projector back further or get a smaller screen. I thought of moving my projector back, but it works at its current position, so I thought why bother. Hope this helps. Perhaps Shawn or others can provide better information. Be safe and be well.

Peace and blessings,

Azeke

You will have more barrel distortion on the screen. That may or may not bother you. In the past I did not like anamorphic lenses because I felt the distortion outweighed the benefits. It bugged me. At 1.41:1 throw distance in my theater - and I have what I consider a short throw in my setup, the distortion is limited to the sides of the screen ( in the masking ) and is minimal IMO. With the DCR lens, the benefits now far outweighed any distortion. 1.40:1 is pretty short throw wise. A JVC RS4500 or RS3000 for instance doesn't quite have a 1.30 throw even in 17:9 mode using the full panel.

http://pro.jvc.com/pro/lens_calc/HTML/jvc_REF.html

And you probably don't want to design a theater with that short a throw. A future projector you might want might not have that short a throw. Don't lock yourself in.

Re: port glass - looks like https://hometheatreglass.com fixed their order form issues, I ordered an 11” x 11” 6mm pane of OptiClear, we will see how that goes.
