They sure don't make them like they used to. Do you have the IIIL?

Sweet! As a former professional photographer who still collects rare lenses I am truly amazed at the workmanship ISCO put into the glass and barrel of the IIIL.

Im an amateur photographer with some really nice glass but seeing something of this size and workmanship it’s like wow.

Here is some screenshot from my ISCO IIIL lens too (it is actually the ISCO 4XL) . The projector is the RS520 on a BD source. (Camera : Canon EOS 5D Mk2 with a 50mm 1:1.4 DG HSM Sigma lens)

The final result of a projector setup must be viewed in real life and not trough the extra components like a camera and computer screen etc.







































The use of more A-lens glass between the projector lens and the projected picture on the screen needs to have some negative effect to, no optic have a 1:1 efficiency.
How ever when the quality of that A-Lens is as high as these high end ISCO lenses, the added chromatic aberration and loss of ANSI contrast etc. is not a problem at all, and the added brightness and extra resolution from the 16:9 projector converted to a 2.35:1 picture is something I rely appreciate over the Projector Zoom solution. I do have and uses the old ISCO II lens too on another HD100 (RS2) projector, and think that is doing a good job too even if it is not as good as the IIIL....

Here is some screenshot of that ISCO II too by the way

Whilst I don't have an ISCO III, I do think that my cylindrical lens is pretty close.

I miss my IIIL, its been sitting in its case for almost 8 years . Images look great! Do you have a Cineslide? If not, I'd highly recommend it, its another "must have" piece IMO.

ISCO was bought out by Schneider and rebranded under their name.

There is not much info around anymore. ISCO shuttered their website ages ago so I have amassed (hoarded) a few PDFs and images from the old ISCO site and a few from the Schneinder site (which they have even deleted) so I can safeguard them.

You can find them here: https://drive.google.com/open?id=1wt...ze8JkVMUizN47X
