I have had a Panamorph FV200 for about 8 months and here are my feelings. My Projector is an LG181d which is bright. I have 3 rows of seating. The screen is 139" wide Dalite Highpower. The projector is mounted in a bar 26' from the screen and slightly above the rear row. The back 2 rows are each on risers. The first thing I noticed when I installed the lens was the brightness increase. The image was bright before but I got a bigger boost than I expected. Some may say it is too bright but I love it. The only time it is an issue is when going from really dark to bright. It takes a second to adjust. My image has about 1/4 inch barrel distortion which is invisible when slightly zoomed on the border. I have the projector mounted in the bar with the lens. I cant get to it unless I remove a cover so I leave it in place and scale for 16x9, which looks great. The image is slightly softer with the lens but overall I like it better. The biggest improvement seems to be standard dvd. I don't know why but the lens helps dvd images greatly. I like having no light spillover also. If I didn't have a lens Iknowing what I know now i would be one again.

Welcome to the lens club. That was the first observation I noted as well. Getting rid of the vertical over spill is a definite advantage of the lens.

The biggest advantage of a lens for me is that it allows you to use all of the display resolution, so with DVD, you may be finding that zooming enlarges the pixels by 33% and looks more blocky, whereas an A lens keeps all the vertical res so the pixel height remains smaller and the image more pleasing.

I first used a lens with a 720 res pj, and the increased resolution was what I found to be a big advantage as I was only watching DVD back then. Zooming worked OK but the image looked blocky and course compared to with the lens. My lenses were a horizontal stretch models - I started with a borrowed H200 lens which softened the image a lot and wasn't really doing anything positive with the image but I could see the potential, so then I bought an H1000 which I could return for a full refund if I didn't like it . That was a huge improvement over the H200 and zooming, so I kept it. I then bought an ISCO II from the avs classifieds just to see what it was like, and found that was a further improvement, so I kept the ISCO and sold the H1000. I later tried it with a JVC HD100 to see if it was up to being used with a 1080 pj and it was, so I still have it. Since then I can't see myself not using a scope screen or giving up the lens until something like native scope pjs come along.

Look out for second user lenses that come up for sale in the classifieds here and on ebay. Prismasonic sell both prism and cylindrical lenses from new with a return policy: http://www.prismasonic.com/english/index.shtml

If your pj does not support the vertical stretch, you can either use an HTPC or an external scaler.
