Hey out there,

Just curious how many of you are using the Angenieux 15-40 and/or 28-76? Just curious if anybody feels strongly about the lens weight shift while focusing? I once did a shot - day one on a job with the Panavision 19-90, where when the lens focused from a middle distance to a close or very close distance, the shift in the elements caused the rig to pitch and roll. It was a very obvious situation and we nevet used the lens on the rig again for that reason. I have done two shows now with these ANG zooms and have begun to wonder if a nagging inability to keep the rig in good balance might be due to this or if I am just finally loosing my marbles. Any thoughts, experiences?

thanks for responding before I actually do lose my marbles.

I have never noticed it, but that doesn't mean it doesn't do it. Why don't you balance the rig on a stand and play with the remote yourself to see how much if any it affects the sled?

I have a lot of time flying the Angenieux compact zooms on jobs and for Angenieux demoes; they pride themselves and their lenses as being Steadicam friendly.

The Panavision zoom is old technology and not really made for Steadi but even so you should be able to manage the slight shift with a light touch.

a heavier bottom, aka faster drop time will minimize the effects...
