Angenieux 12-120 with c-mount
chuck colburn replied to Uwe Hoferichter's topic in Lenses & Lens Accessories
There is a tool Angenieux made for adjusting their spring loaded "C" mounts on their zooms. It's called a "T" wrench. Any rental house or repair shop has a bunch of them laying around. Should be free or at the most a few bucks. -

What John says. -
Annie did you get my PM about the lens? Something was going wonky (good chance of operator error) when I was trying to send it.

Go to the site listed below and look under "Newbies" or "operating and type in video. Lots of info there. http://www.steadicamforum.com/forums/index.php?

You could shoot on 65mm film and transfer to video.

That's what I always understood it to mean.

Yes, the academy members nominate the films.

And since Eyemos are getting harder to find (use to buy them by the crate for $25.00 apiece) the 2C's make nice crash cameras too.

For those of you stateside, you can buy it from Dereck Whitehouse. Probally save on the shipping that way.

4D Cinema? What time do I get there to see it? Before it starts or after it's over? lol Looks interesting though. -

Well unless they have in house film processing it's going to take them as long to do a reg. test (if not longer) as it would you. But anyhow what you want to know is if the camera is steady and the film plane is seeing the same as the ground glass and that the lenses are properally collimated to infinity focus. And that your zoom is set up right for front and back focus so that it holds focus as you zoom. They know what to do. It won't be cheap at Arri for this type service. Mayby there is an independent service tech or rental house in your area that offers this service for less.

Hi Annie, If possible, could you post an image of that exploded view? thanks, Chuck

When doing your steady test use a cross hatch target with vertical and horizontal lines in a grid pattern. Make one pass (underexpose it one stop) and rewind the film. Then offset your target slightly on the vertical and horizontal planes for the second pass. This will let you detect weave in the gate by looking at the vertical line pairs and detect any registration problems by looking at the horizontal line pairs. Be sure not to move the camera between the two passes.

16mm C-mount lens for Beaulieu 8mm camera?
chuck colburn replied to Hampus Bystrom's topic in Super-8
Thats interesting. I probally looked at at least a hundred each and chances are many more than that over the years when I did lens repair. Since both designs are fixed focus and have to be spot on in their backfocus adjustment, perhaps the one(s) you saw were out of collimation. The Ang. 10mm takes an optical tech with an autocollimator at the MOST, ten minutes to adjust. The 5.9 a bit longer. Anyhow new, cheap and wide angle don't live in the same town let alone the same state. lol good luck, Chuck -

16mm C-mount lens for Beaulieu 8mm camera?
chuck colburn replied to Hampus Bystrom's topic in Super-8
Two nice wides that can be had in "C" mount are the 10mm f1.8 Angenieux and the 5.9 Angenieux also I believe at f1.8 The 5.9 has very good rectilinear correction for it's focale length. -
removing Beaulieu "Reglomatic" from Optivaron 6/66.
chuck colburn replied to Benjamin Coppens's topic in Super-8
Every still camera mount to "C" mount adapter I've seen or checked was assuming a standard .690" "C" mount flange focale depth. I doubt if the Leica to "C" mount adapter is otherwise. Since I would think that the manufacture would want it to work on any "C" mount beit Beaulieu, Eclair, Bell&Howell or whatever. cheers, Chuck
