Zoom movement on Angeniuex

Luigi Castellitto · October 29, 2016

I'm sure that the experts know the answer, it's a simple question.

It's normal that in an old Angenieux lens — in my case is a type 8x8 B 8-64mm/1.9 — the small screw that lock the plastic ring where are written the numbers of zoom (it's only one screw, the rest of the parallel holes are for the zoom stick) also "control" the "smooth" of the zoom?

So: screwed tighter, harder zoom movement (up to block it, amost), screwed looser, softer zoom movement.

Thank you! :)

1) It's always the same model? When you say "Angenieux Type 8x8 B 8-64mm/1.9" is always ONE TYPE of model, which is mounted indifferently on a Beaulieu 4008 ZM2 or mounted on Pathè Webo BTL DS8?

2) If I wanted to use the same lens (one in the the second link) on my Pathè Webo BTL DS8 I should remove the entire motor? It's correct? Under the motor there should be a ring with "teeth"?

3) I already have a Beaulieu 4008 ZM2, but with Schneider Kreuznach Optivaron 1,8/6-66 mm and motors for iris and for zoom. If I want use on my Beaulieu the Angenieux lens of second link, I should use the motor that is already on the lens or one (with two motors) that I have on Schneider Kreuznach?

...BUT why these lens (on more ad) are branded "for Beaulieu 4008 ZM2" if it have the motor only on iris? It is not the Beaulieu 2008 that have it only on iris?

I don't think there is an adjustment for zoom friction on that lens, more likely you are just screwing into the barrel and causing a deformation that makes the zoom feel tighter.

The basic lens design should be the same across different cameras, same C-mount flange depth, but they won't all have exposed gears to accept iris/zoom motors. The Beaulieu motors can be removed easily enough by undoing the screws around the base.

I'm not 100% sure, but I don't see why the second link zoom shouldn't work on a 4008ZM2.

Thank you! :)

And, in your opinion, the lens of the second link works on a camera model (Pathè Webo BTL DS8) like that in the first link? Obviously, with disassembling the iris motor.

Note that the camera of the first link should have an EQUAL (maybe!) model of lens, without any motors.

It should work, yes.

Thank you, Dom!

And what you think about question 3)? Now, on my Beaulieu 4008 ZM2 I have Schneider Kreuznach Optivaron 1,8/6-66 mm with two motors for iris and for zoom.

If I want use on my Beaulieu the Angenieux lens of second link what motors should I use? If I let mounted the motor already mounted on Angenieux, I would have only command to the iris, while, if I unscrew from the Schneider the two motors and I mounted them on Angeniuex, I would have two motors, for Irises and zoom? It's correct?

I don't think that lens has the exposed gear needed to fit a zoom motor.

Besides, why would you want to use that Angenieux zoom when you already have the superior Schneider?

You're right, Dom, the Schenider is superior, it's true.

My is only a curiosity, because, I bought one like this (http://www.ebay.fr/itm/Objectif-Angenieux-zoom-type-8x8B-f-8-64mm-1-1-9-/141707020771) for my Pathè Webo DS8 BTL, and I thought it might be good to "alternate" it also on Beaulieu, with Schneider. Only with the idea that the spending for lens would take me even another use.

But, in the end, is best to keep it just on Pathè. Thank you.

Only for cultural info, sorry for pedantry, Dom and all :) : you talk about "exposed" gear, but in this model of Angénieux the gear for zoom does not install with a component that "ties" on the lens?

And iris with a ring that is installed with screws?

Maybe I'm wrong and they are different models.

With component installed:

Without component:
