Hi Mike. Ok, appreciate that.

My initial follow up is what is the difference between saving the zoom, etc ("Lens Memory") to achieve lens-less anamorphic and using a video processor such as the Lumagen Radiance? The Radiance can be used to get to the same end, but apparently by different means than physical zooming of the projector.

The Radiance (or any video processor) can't change the size of the projected image, it can't make the image larger or smaller. All it can do is change how the image coming into it is sent out of it. Lens memory saves both lens shift and zoom, meaning it can save different image sizes in addition to positions.

The closest you can come with just a video processor, is zoom the projector out, and you can shrink the image with the video processor, but this means you lose half of the resolution, instead of 1920x1080, you see 1440x810.

Correct, so like with the zoom method, you do not use the pixels or light output from the black bars when projecting 2.35. On top of that you lose more resolution when watching 16:9.

Though with a really bright 4K projector, maybe neither are such a big deal?

Screen size and viewing distance would still need to be taken into account. I view from one screen width.

True, though if you're OK zooming, then pixel density probably isn't an issue. And since most sources are still 1080p, you don't lose anything for 16:9 with a 4K projector.

That said I think I'd still prefer an ISCO in front of any 4K projector I get. I just haven't been that thrilled with the Lens memory on my JVC. It works fine, it's just annoying, and it's not as bright as using a lens.

I use an A-lens myself. Prismasonic HD6000 on a powered slide mounted to a custom plate that is attached to an RPMA020.

Seems like I'm jumping in the conversation at right time. Currently I'm using a 145" Acoustically Transparent screen. I use Zoom feature to stretch the screen to fit 2:35 screen. Since my screen is AT, it has a screen gain of 1 (or even .9).

With that out of the way, can someone please tell me the difference they see with/without lens on? How much of a brightness difference do you see?

Also, I'm considering to go with a curve screen. I don't care about how cool i'd look. My only reason to go for a curve screen is to get more immersive experience. Does anyone here have a large curve screen? Can you please share your experience? Or if anyone thinks that its a bad idea, please do share.
Thx.

I've got a custom size 128" 2:35 in Screen Innovations AT material that's curved. Compared to my other two 2:35 screens, the curve is a bit annoying to use with the 500ES as you have to always over zoom the image slightly to compensate for the curvature of the screen and what that does to the the bottom corners of the image. It's not drastic but a little annoying:

It depends on the projector and the setup. With my JVC RS4910, at the throw I have it, the difference is about 10% more light/brightness with the lens.

Don't get a curved screen unless you get a lens, the purpose of the curve is to cancel out the pincushion created by the lens.

If you want max brightness out of a projector, then A-lens, short throw and curved screen will get you there. I have a short throw, curved screen A-lens setup.

Yes, i also use my 500ES with a curved screen and A-Lense. No problems with the picture fitting thanks to blanking. More light, higher resolution!

So you overscan to throw the pincushion distortion caused by the A lens off screen, top and bottom, and then blank which pretty much costs you the light and extra pixels you gained in the first place.

If his setup is like mine, he has very little pincushion, due to the curved screen, so only has to overscan around 1/4" to 3/8".

The pincushion with a curved screen is indeed very very low and the blanking is a few centimeters only ( I think I am using 5 in the settings) due to a perfect throw ratio. The resolution gain is incredible and the 21:9 cinemascope stands above all for me!

That's good to hear. What is your throw ratio and what is the width of the non stretched image, i.e., for the 1.78 size screen that would lie within the anamorphic screen?

Does it mean that Sony will start shipping its replacement (american counterpart of VW520ES) sooner rather than later? VW520ES is expected to be available in October. As I understand there is no difference between 5xx and 6xx models so US availability date should be similar.

Not until after Cedia October 14th through the 18th. Not 100% sure of a ship date - yet.

Have you used 500ES on flat screen? If yes, do you find curve screen more immersive? Also, How big is your curve screen and how does it look if viewed from side seat (one beside the center seat). In my case, its my wife and I watching most of the time and therefore all that matters is the center seat and the one beside it. Currently I have 145" flat AT screen and no lens. I use zoom + memory feature to watch 2.35 and 1.69. I sit around 11 feet from screen.

How much do the A lens go for with the motor? Trying to figure out how much would it cost me if I wanted to go for Curve screen with lens. My main reason to go for curve screen is to get more immersive experience as compared to flat screen.

Thx a bunch.

Sony has released and shipped new models shortly before Cedia before. I think having a small amount of the old model in stock or having none would have no effect on the release date. I expect Sony will let dealers order the new model when US pricing is set and obviously could set such pricing whenever it wants and will ship as soon as stock becomes available. I think Sony will start accepting orders about 2 weeks before Cedia and start shipping just before Cedia. Just hunches based on race horse past performances.

The VPL-VW620ES. Read the IFA thread for the details on it. The model discussed in that thread is the VPL-VW520ES (the European etc model number) for what will be the VPL-VW620ES on this side of the pond.

Thx a bunch.

The main reason for using a curved screen with an A lens is to reduce the amount of pin cushion distortion that an A lens causes. Also the curve may increase the sharpness of the image because the A lens pretty much destroys the depth of field of the primary lens. Proper set up including set up at long throw is required to maximize performance of the screen towards these benefits and for maximizing the optical performance of the A lens.. Further, usually only two radiuses are available for ordering a curved screen. Unless you sit very close to the screen and set up for the shortest radius curve you can order, increased immersion will be minor. Sitting one seat off center will be improved with a curved screen. BUT, the cost of a cheap A lens, a motorized A lens sled, and a curved screen will easily be in excess of $5K and likely will not give you what you really are looking for. For that you need a commercial movie theater with a large tight radius curved screen which are rare and you need to sit within the curve. Washington, DC has such a theater.

Thx Mark. I think I'll just stick with Flat screen.

One more question: I currently have around 950 hours on the bulb now. I have always used it on low. When is it a good time to replace the bulb. I assume after 1000 hours, its better to run it on high?

Without a light meter reading one can not really know. If you think it is too dim for esasy non eye straining viewing, run it at high. You can tryit both ways a decide if you need to run it a high now. Probably you don't for a few hundred more hours but I am just guessing.

This is becoming a more FAQ as our units age. My bulb has over 1300 hours and still looks great on low. I did run the auto-calibration sequence at around 1000 hours and it bumped up the white level just a bit; a very minor change. That's what I'd recommend instead of switching to high. I also have a spare bulb stashed away just in case.

Broadly speaking, what is an ideal diagonal (scope) for the 600ES and at what size is quality going to begin diminish too much for the typical videophile (assuming 1080P blu-ray content)? Also, are there certain screens which have been found to work well with this projector?

Stereo: Cary Audio 306 SACD Pro | Cary Audio SLP-05 tube line level | Cary Audio SA-200.2 | Focal Diablo Utopia III
