1) It's always the same model of LENS? 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 lens like one in the second link on my Pathè Webo BTL DS8... So, I should remove the entire motor? It's correct? Under the motor there should be a ring with "teeth"?
3) I also already have a Beaulieu 4008 ZM2, but with "Schneider Kreuznach Optivaron 1,8/6-66mm "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 and on web) are branded "for Beaulieu 4008 ZM2" if it have the motor only on iris, only one side motor? It is not the Beaulieu 2008 that have motor only on iris?
Thank you!
