Took this to the holiday meeting of the Ohio Camera Collecting Society. Everybody agrees it is cool
The Makiflex Automatic (because it has an auto-iris mechanism in the lens).
I have the Plaubel 180mm Auto Schneider Xenar, and the Plaubel 240mm Auto Xenar. Other lenses that were notable, and available in Auto, were the 150mm F2.8 Xenotar, the 360mm Schneider Tele-Xenar, and the Schneider 240mm Tele-Arton.
I now have received thirteen Lisco, Fidelity, Graphic, and Fotac 2.25"x3.25" Film Holders, to go with my new Plaubel Makiflex 2.25"x3.25" Film Back. Enough to do twenty-six shots without stopping. And also, I just received 100 sheets of 2.25"x3.25" Aristo.Edu 400 Ei film, from Freestyle Photo.
This has taken awhile to get together, but now I am ready for Spring shooting, with all this new stuff. I can process twelve sheets at a time, in a Honeywell Nikor 2.25"x3.25" film rack, which neatly fits into a two-reel Honeywell Nikor film tank.
