Q. HI; I am still kind of new to the projector world. I purchased my projector in May 2012. The models is Panasonic PT-AE7000. My second screen is a Black Diamond Fixed Series 133" 1.4 G with aspect ratio of 2:35:1. Obviously I've done my homework. What I am curious about is anamorphic lenses. When I looked into them it made me wonder if the price justified it. Most of my Blu Ray content is in 2:35:1 and the zoom feature on the Panasonic stretches the image to fill the frame with obviously loosing resolution. I guess my question is, is it worth getting an anamorphic lens for my setup? By the way the anamorphic lenses I looked at were $2,000 -$3,000 by companies like Panamorph.
Answer
I use a Prismasonic http://www.prismasonic.com/english/description_hd5000m.shtml
Personally I think it's worth it but I've seen others argue in forums that it isn't. You don't really lose resolution by using the magnification you just lose imaging device surface area. A 2.4:1 movie is about 800 lines with the rest of the 1080p being black bars. Scaling just reorganizes those 800 lines to fill the imaging device, it's still 800 lines of information. (it becomes a simulation of 1080p) If you have plenty of lumens from your projector then try it with magnification and see how it looks. If you are marginal on lumens then every little bit helps so using the entire imaging device and an anamorphic lens would help.
Btw, the nice thing about the Prismasonic lenses is that they are adjustable. You don't have to move it out of the way for 16:9 content you just adjust the mirror positions. You can have constant image height on any aspect ratio from 4:3 to your screen aspect ratio of 2.35:1.
Edit: Btw, what are you using for scaling? With a constant image height system you're going to learn to hate the people that make Blu-Ray and DVD. The aspect ratio is all over the map, the Menu is one aspect, previews are all different aspects depending on the movie, the movie is still a different aspect. There isn't much they can do about the previews since every movie can be different but they should at least make the menu and the movie the same. You're going to want to have a one button aspect selection so you can avoid having to dig deep into menus between the top menu and the movie. I use the RS232 input of my Anthem D2 to control aspect through an IR to RS232 device from Industrologic. With RS232 commands I can instantly jump to any scaling setting. You will need to look into your device for this whether you are using the projector, the processor or an external scaler see if you can input scaling commands directly.

Are you a receptor or a projector in this world?

Do you, in life, feel that you take in more that there is to receive from the world (such as adventerous experiences, knowledge, cultures, entertainment, theory, anything enjoyed by the senses or the brain), or that you give out more (in thoughts expressed, ideas published, any sort of performance for others, gifts, charity, religious ideology, etc)?
Answer
you know, i often ask myself this and the answer is always the same, i give more, to much in fact...then when it's my turn to take a Little back there's no one in sight!
