Anamorphic Lenses

[NBPk402]

Another zoomer here. My projector is currently mounted slightly off center so I'm not sure if a lens would even work for me. I could use the extra brightness but I assume I'd have to get the projector mounted perfectly center to use a lens?

Ideally...yes, but with my setup I set the projector up as close as possible to perfect, and then used the lens shift to get the last little bit. If you use just a little bit of Lens shift it works out nicely, but if you want perfection you need to def have a curved screen IMO.

so using one instead of zoom...requires a curved screen?  Im interested with using a rs400....right now I have the zoom maxed out to fill my screen

With a flat screen, you need to use the long side of the throw range. That minimizes the pincushion, but in doing so, you are giving back some of the brightness that you gain by using the lens.

defeats the purpose imho

Keep in mind you do gain other benefits with an A-lens.

1.  Changing aspect movies do not hit above and below your screen.
2.  Quicker aspect ratio changes.
3.  More accurate aspect ratio changes.
4.  Still gain light output.
5.  Higher pixel density.

I agree. In my setup it also gave me another 10" of diagonal over zooming, and a brighter picture.

so just to confirm....from a 13' throw distance on my 130" screen (flat) i will have a distroted image if i just buy an A-lense?would 100% need a new curved screen?

unfortunatly as I suspected this is way out of my price range....i will stick with the zoom meathod

Yes, with that short a throw, you would need a curved screen.

Lens is not too bad...I picked up a used B-Stock one for around $1k, but for me to take my T-channel frame and make it into a curved frame would be another $1k or more.

Depends. A good lens can cost a lot more than that ( I wouldn't be happy with less than an ISCO II lens ).

I think those are out of my budget too...I will have to stick with my Panamorph UD-480 lens, as that is max I could afford at the time, which is more than I could afford now.

Now that most projectors are offering zoom/focus memory I have not touched an anamorphic lens in years and have no idea what is avail these days as well as sleds.

Lets start a list to include options, everyone's contributions are appreciated. Maybe starting a dedicated thread would be ideal but lets get this started here first and if it warrants it we can move the content to its own thread.

Hi, I am still using a JVC HD100 (RS2) with a ISCO II anamorphic lens on a 120" curved screen in my home cinema.

Have no slide for the A-lens because this ISCO II lens need the projector to have lens memory so the 16:9 picture is zoomed and shown correctly onto the screen when switching.

Uses another JVC HD1 for 16:9 instead.

Curved screen solves the pincushion effect from the A-lens, but because of the curve, the screen material start to "see" the picture side to side, and the screen should have higher gain to reduce the reflection cone so it is smaller than 180 degrees and do not reduces the contrast.

I have the Panamorph 480 motorized lens and am having trouble with the remote.  Is there a way to replace and/or purchase a new one?

Have you asked Shawn at Panamorph ? Send him an email - maybe he has replacements. shawn@panamorph.com

What about using a universal remote? I use a Harmony to move my lens in and out of place.
