IS lenses for Shoulder Mount?

[Amuse-WS]

I've been doing as much research as possible for my potential purchase of a 70-200 f/4 IS or 70-200 F/2.8 (non IS).

As far as what I could gather, the IS seems to help boat loads when going hand held - and I've seen clips to support this. But, handheld is quite different than shoulder mounted rig setups - which, if my camera was not mounted on a tripod, it'd be mounted on a redrock shoulder rig that was balanced.

So my question is, with the camera mounted on a shoulder, using a non-IS zoom lens (considering, I wouldn't be at the end of the zoom most times) - say I were more than adequate shoulder-mounted camera operator, would I still be getting some good quality (non jittery/jello) footage with a non IS 70-200 f2.8 non-IS? Or is the IS that essential, even when using a shoulder rig?

Thanks, and I apologize for my bad grammar, not enough sleep...

Reasons to get the f/4 IS instead of the 2.8:
1. You never know when you'll need four stops of IS.
2. The f/4 IS is the sharpest of all four Canon 70-200 lenses.
3. It's smaller and lighter.

Reasons to get the 2.8:
1. You're a pro who needs to shoot indoors.
2. You can't sleep at night without knowing you're getting the creamiest bokeh.

I don't know if your shoulder rig would stop the jitters while using a 70-200 non-IS zoom but I highly doubt it.

bummer - I was really hoping I could save $700 and get some other equipment by not going IS, with a more stabilized shoulder mount setup.

Thanks for the input.

I don't understand. The 2.8 non-IS runs around $1300, the 4 IS, @ $1200. Where's the $700 difference? 2.8 IS?

Try them out in the store or rent them to be sure.

it's a weird budget scenario

But as you said, I may as well rent both IS and non IS. I'll probably upload a video comparison as well.

The soulder mount should help the non IS set up on the wide end but when you're on the far end of the lens then you'll have trouble. I tried it this weekend with the redrock shoulder rig and a 100-300 non IS lens
