http://www.youtube.com/watch?v=ivvcW-t50sI&feature=youtube_gdata_player I seen this as the most inexpensive way to get a 2.35 look Oz This real or a gimmick if not fake how on the heck you do it.

The guy is using a camera (as in capture) wide angle lens, not an anamorphic projection lens. Yes what he has done works, but it is still the zoom method, not the method used by the rest of us in this thread.

I love my Constant Image Height system!

These types of anamorphic lenses are not only corrected for CA (ie there is NONE!), they are also corrected for geometry issues like grid distortion. What sets them apart form any other type of anamorphic adapter is the continuously adjustable astigmatism correction which allow the user to focus the vertical and horizontal lines at the same time at any distance.

A prisms based anamorphic adapter may have additional correction elements (usually cylindrical) but the optics are fixed and non adjustable. Therefore what you get is really dependent on the installation and where both the throw ratio and the throw distance come into play.

Hope that helps.
Thanks

So basically can it be done? I live in a area that has no stores like this to buy from. I am not big on ordering online only for the reason, that i dont want to end up getting the wrong thing only to have to send it back. I am completely new to doing the whole home theater thing. I am also wondering if this method would get rid of letter box top and bottom black bars or if this is only for 16.9 ratio movies to stretch the image to a 2.35? Howmuch would a lens like the one your talking about set me back 1000+ ? Im a waiter so this be out of my range if so.

This Method he has done would work fine for me but , to you does it look just like a 58 mm lens wide angle to you or is there more to it than that. I am also curious to know how he attached it. I am also curious if it would get rid of the black bars in letter box? I mean i dont want a 2.35 ratio with black bars . Thanks for all the info you have given me so far.

cpt: This is Off topic. This thread is for posting photos of your complete 2.35 lens setups.

If you can't afford an A-lens there are ways to do it for free. But here isn't the place to ask. If you'll start a new thread on, how-to's, feasibility, the expansion lens, whatever, we'll all appreciate it. And you'll get more help and input that way. Thanks, Scott

this is my DIY anamorphic lens, prisms were a panatar lens for 35mm projection fits this case the metal, leaving as light and simple. I must say that it fulfills its job perfectly. the use in my optoma HD70 and now with the HD20. high brightness and contrast.
sorry for my English use google translator.

My JVC X95 with Cineslide and Schneider M lens is housed in a projection booth in the foyer of my home theatre. The booth has a drum extractor fan expelling the hot air to the outside, this also makes it completely sound proof from the auditorium.

Here's my setup -- JVC RS20 projector with a Prismasonic HD-5000R lens (private-labelled for AVS!). I've been very happy with the results...
