Hello, Bonjour! I hope English is OK. My French is terrible and I wish to be respectful to all readers.

 

No one seems to be able to answer these questions so I turn to where I probably should've' gone first, here.

Sony support, my local installer and the product manual does not have the answer.
I need help from an actual owner of this projector (VPL-VW1100ES)

 

I intend to use this projector in a planetarium with a hemispherical mirror system. (http://paulbourke.net/dome/)
I currently have a very good setup with 1920x1080 Epson.

The Epson specs did not list the minimum focus-able throw at 1 meter, but it does.


This answers will determine if we upgrade and I (and my students) REALLY appreciate your help on this.

 

Questions:
What is the ACTUAL minimum throw distance this projector will still focus? (1 meter?)
What is the size of this minimum image?
Rear Projection option, Yes or No? (image inverted)

 

Thank you and Merci Beaucoup!

The minimum throw you can use is 1.25 times the screen width. At 1 meter throw the image width for a screen occupying one plane would be 0.8 meters. I will try this for you later to see if such a screen width will work while being in focus.

I do believe the projector has the necessary inversions to do rear projection with a mirror.

Thanks Mark,

I appreciate your help and this calculation as it brings up a mathematical way to rate this project "go or no go."

 

The first surface hemi-mirror is 0.45 m wide and the image would have to fit onto it.

Reversing your calculations then, a "focused" throw would need to be ~0.56 meters.(not the rough 1.0 meter I pulled out of the air.)

There are larger Hemi-Mirrors too?

I measured the current Epson setup and sure enough...it's at 60cm throw.

 

By the way... I'll post the results on the international planetarium list serve and this knowledge will be multiplied as I suspect other small planetariums around the world will duplicate once they are set up here and proven and each theater has thousands of visitors. So in a way you're enhancing tens of thousands of people's experience, mostly kids.

 

PS Sony got back to me, they don't know the answer, but will dig in and he did tell me that the ship date on the 1100ES have been moved back from December '13 and that April '14 (early) is the next ship date, confirming Grifo's post. I asked why the move and he said it's all the way back to the factory but didn't know what the hang up is.

I still need to check if the image will be in focus. The throw and screen width are physically possible as long as the throw is 1.25 screen width or greater. Mike G of AV Science seemed to remember reading somewhere that a throw of 5 ft minimum was needed for focus but I have not found this and need to verify whether focus will be maintained on a very small screen. Later today.

Mike is it a noticeable difference while watching a movie going from say the sony 1100 to the jvc rs45? Is it nite and day difference or is it just minor? Be honest.

I will answer this from the perspective of my 600, rather than the 1100, since I have not viewed the 1100 enough. Black levels between the 45 and the 6009 are close and would need a side by side to tell the difference. Panning motion goes to the Sony. Brightness, sharpness and resolution goes to the Sony. So in my room the 600 easily gets the nod, but then it should at the price difference. With my 9' wide 2.40 0.85 gain screen the added brightness is much appreciated.

I will tell you that at my size screen I cannot go back to a 1080p projector. Perhaps an anamorphic lens would make the difference, but I dont have one. I NEED the 4k resolution to not be distracted by pixel size on 2:35 content at 161" wide. Your mileage may vary.

If you had a higher gain screen or if the JVCs were a little brighter, eshift would solve that issue for you on a 1080p panel. But other than black level and contrast that would be a backwards move from the 1100ES.

Anamorphic lenses shouldn't degrade pixel structure or SDE. If it does you have a poor quality lens. I know both the ISCO IIIL and UH480 I have don't degrade pixel structure or SDE.

I've set up my VPL-VW1100ES with ISCO 1.25x A-lens (woo hoo! yes!) - getting a beautiful image that's 167 inches wide but only 64 inches tall (2.60:1 AR) with Aspect Ratio set equal to V Stretch. Why is this? I've of course picked the 1.24x lens option under Installation. But even without the A-lens, when I click V Stretch AR, the top and bottom of the images are cropped by a few inches. Why does this happen and how to fix it? I've played around with Picture Position stuff - but this doesn't do anything as far as cropping goes. I'm sure someone knows the answer to this - I called Sony and they were clueless - they've never even seen an anamorphic lens-smile.gif When I try to play a bluray disc, I have to change AR to like "Squeeze" or "Normal" or something else to even access disc menu since they're mostly at the bottom - but end up getting cropped when I click "V Stretch" AR.....
