Telescoping lens with the FS-100

Anyone using a Sony FS-100 with the stock 18-200mm lens on a Steadicam-like stabilizer knows how the telescoping or extruding elements of this lens immediately affects the pitch balance of your rig, once you zoom in for a tight shot.

Have you seen or heard of a solution for this?

If not, has anyone at least experienced this particular issue first hand?

If you have, then it's not just my imagination. Other people beside myself probably had the same experience.

Here's the good news: I solved the problem:


Go ahead and build one for yourself. It works like a charm.

If you have any questions, feel free to ask.

Brilliant! Is the slot for the weight milled, or are those holes?

Re: Telescoping lens with the FS-100

It's milled. I had it made at a machine shop.

Hopefully the pictures will give you a better idea.

I have no doubt that you can greatly improve on this design, as it was originally built for an entirely different purpose.

Please post pictures of it when you do.

I'd love to see your improvements.
