    I have the same math. The only thing I'm having trouble figuring out is how the powers interact (ie, what power glass would shorten the distance of movement required to focus)

    Just got a hook up with an optician that works locally and has some tinkering toys at his house. Hopefully I'll gain more info there.

    HD should be up soon but here it is.

    I'm using plano-convex lens mounted to the front element of my anamorphic. On the rails, I've mounted a plano-concave lens (pretty ghetto set up, but works enough for proof of concept). Moving the rail mounted lens further away gives me closer focus, in fact, pretty fucking close. Sharp as can be too. All I need to do now is figure out the power of the lenses, buy larger elements, and house them. Baby steps.

    Wide angle seems multi element, as does the macro element, unfortunately too strong. I threw an old 10+ diopter in and the focus throw seems about right. Terrible blur due to the single element, I assume. I've got some Surplus Shed glass coming in, so I'd rather hold off and play with that until I splurge for a +10 achromat. Anything vintage that is achromatic with that kind of power?

    Scored a Vivitar .43 Wide Angle and a 20+ Tessar diopter today at a small camera shop. Tinkering soon. Very interested.

    Well since we're hammering away at this, I'll chime in.

    I'm all for the democratization of technology. I saw these (FM whosawhatzit) and immediately started pouring over patents and the such, shortly finding that Iscos are afocal blocks with a variable diopter in the front. So here we have to individuals capitalizing on this "revelation." God Bless America. I, on the other hand, and planning on finding a cheaper solution with some "surplus" (surplusshed.com) and some shoddy test builds. Lucky for me, I have a friend that currently has a satellite (imaging, of course) in orbit and he's more than happy to hash out some details. Once I have some concrete findings, I'm sharing it with the world wide web. Every creative can benefit from this.
     
    Preach on @tonydtv!

    Give that a go. Teleks are no longer made but have varying negative powers.

    I can still get infinity focus.

    I only paid $150 for the B&L so cutting it wasn't an issue.

    Quick test of a flat Camera Raw treatment and 4K upscale. Holds up pretty well, contrasts back down and resaturates well. This is only 2k due to the monitor.

    Finally got this beast up and mounted. I can focus through within about 7-10ft of the range I set on the anamorphic with only the prime, flares a decent amount, and is sharp as a tack. Squeeze ratio actually came out to about 1.8 in post. Pretty pleased with a 3.2:1 ratio.
