Double panamorph?

334 Views 5 Replies 3 Participants Last post by  jdaniels
Hi all,

I was noticing some of the 16:9 projector owners were using a panamorph or similar to stretch to Scope (2.35:1) screen size. The stretch from 16:9 to 2.35:1 is apparently similar to 4:3 to 16:9.

Could D-ILA owners put 2 panamorph or ISCO lenses in sequence to achieve 2.35:1 , or would this introduce too much distortion given that there is already some barrelling with one anamorph?

Could one combine a vertical compression lense with a horizontal stretch lense to cancel the barreling artifact or would they be additive artifacts rather than canceling?

Ive tried this but the aperture is not large enough on ether lens.

If your projector had a really long throw lens this may work.

There are also Panamorph lenses that go all the way from 4:3 to 2.35:1. No cancelling of the effects that way, though. Alan sold me his, but I won't be able to try it for a week or two on my SX21. I'm not sure if I'll keep it, but figured it would be fun to play around with. It does require a long throw from what I understand, though.

Thanks guys,

My projector is the G1500M with the fixed 1.5 throw. Do you know if this is too short to use the 2.35:1, and for that matter can the 4:3 to 16:9 panamorph be used at this throw effectively?


1.5 is a short throw.

There is the Jumbo Panamorph also. I wonder if that placed in front of the panamorph would be a possible winner.

Do you currently have a panamorph?

No, I just bought the projector and don't have it yet. The throw is OK for my theater (same as CRT) but it sounds like the anamorphic lenses may be an issue.

I am looking at the install as somewhat temporary with new technology in the 1080p range looking good within the fairly short future. With this in mind, I suppose it might make more sense to stick with a regular lense that can be in turn used to bump 16:9 to 2.35:1 in the future.


I tried to PM you back but your mail was full. I'll try again later.
