Hi I have a Panasonic AE4000, Oppo BD93, Integra 8.8 Receiver & a Elite screens Osprey Dual tension screens which has a 117" 2.35 screen & 94" 16x9 screen.
I am currently using zoom to fill the screen. My projector lens is 13 feet 3 inches from the screen.

I have recently acquired a Anamorphic Research AR2 lens with astigmatism correction lens and manual slide.
I dont have a separate video scaler yet. I calculated my throw ratio will be 1.8

I was wondering can I use the A-lens properly without a scaler? If so what settings should I employ to scale correctly for 2.35 and 16x9?

thanks

The Oppo BD93 can do the proper scaling - use the Zoom button on the remote (and see the Zoom topic in the manual). One of the zoom settings (first one, I think) scales 33% for use with an anamorphic lens.

So use the zoom feature with 2.35 content and the lens in place. No zoom for 1.85 content and the lens moved out...

Enjoy!

Jeff

Zoom? Ok I thought use of A-Lens negates that need. I'll read the manual on zoom.
Also does V-fit aspect setting on the Projector do the same thing?
Thanks

Most Panasonic home theater projectors offer rudimentary stretching modes in the projector. So a V-stretch mode in the AE-4000 should be fine for most movies. The 4:3 mode in most projectors is a good compensation to present 16:9 content while using the lens. The only exception is movies with specific aspect ratios (The Leopard, Patton 2.20:1) or subtitles placed in the black bar, which requires a HTPC or Oppo blu ray player to adjust to screen.

Thanks, got it working also had to tilt the lens slightly downwards, still have a couple minor geometry issue to correct.
I can definitely tell the differnce between zoom vs lens. My seating distance is approx 11.5 feet I can see a brighter and sharper image. I have noticed CA when pausing the motion to check difference between lens and zoom but don't notice it during the movie.

'Ill take some pics.

Yeah, their word, not mine... Although I can't think of a better single word to use on a remote for those functions, either. "Scale" would be technically correct, but would be a more appropriate button on a Bass-o-Matic(tm). biggrin.gif

I've recently been looking at Video processors, wondering if it's worth getting something like the DVDO Edge (now the Edge Green) since its a good price.
I would like to have at least the Aspect controls my AE4000 has including the ability to blank all 4 sides of the picture independently.
When I had the AR2 (looking into replacements) I'd zoom a little to compensate for pincushion and use the blanking controls on my PJ.
I have read the user manual for the DVDO and I can't find this feature. The AE4000 appears to have more picture control than a DVDO Edge. Unless firmware upgrades to the Edge have enabled this?
