Large Fresnel Lens

[SAShruby]

I'm looking to put fresnel on my 8x20. I found so far one source...

1000mm Fresnel

A little downsize is that focus point is 1000mm from camera back.
Did anyone tried it? Any experience?

Check with Tracy Storer at http://mammothcamera.com/ or through this forum. He set me up with a fresnel for my 12x20.
