What’s the ‘other’ method Randy? Doesn’t it use a different type of lens? Vertical compression? I can’t quite grasp that technique.

If your referring to a vertical versus a horizontal type lens, they really do the same thing, but in a different manner. In both situations, you first have to scale the 2.35 image (vertically stretch) to reclaim the black bars.
The horizontal lens then takes that image, leaving the height alone, and horizontally stretches it back out to fill your 2.35 screen. In my opinion, these are best if your limited on depth of your room, and trying to achieve a big screen from a shorter throw distance.
The vertical design takes the same image and compresses(squeezes) it down from top/bottom until it fills your 2.35 screen. I think most people that use these types of lens, have a longer throw type projector, I don't think they would work that good from a short distance as your end result would be a smaller screen.
Hope this answers your question.

So if I understand correctly the horizontal lens is good for a constant height system while the vertical lens is good for a constant width system?

I could be wrong on all of what I said above, just my understanding. I'm sure Panamorphs website would help to understand.
A Vertical squeeze design would seem to work better for constant width setups (where both 16:9 and 2.35:1 are the same width), where as horizontal stretch would seem to be ideal for constant height setups where you want the 2.35:1 image wider than 16:9.
To me an anamorphic lens is only worth it if you go constant height. The whole point of an anamorphic lens is to recreate the cinema feel by making 2.35 movies wider than the rest.
If your limited on the width of how big your screen can be, then a vertical design might be an option?

I would go with the same setup as yours, makes more sense.

I agree. I think it is easier.
Randy, did you buy your lens direct from the manufacturer?

Yes, there was a "Power Buy" on AVSforum 6-8 months ago from Prismasonic so I took advantage of the better pricing. I think Panamorph just recently came out with a horizontal design as well, not sure of the pricing. Ok I'll check......
.....
Looks to be $695 right now, not bad...you would have to read the specs to compare to the Prismasonic...

It appears my model is currently selling for around $1100 USD, it will fluctuate depending on the Euro conversion each day.

Ack! "Timing" and I don't seem to go very well together. Maybe they will have another one of these days. It will be awhile before I am able to get the lens anyway.

I know recently Prismasonic was offering a DIY kit, where they send you all the stuff with instructions on how to put it all togethor. Not sure if that is still an option...
