Just thought I'd put my two cents in on this issue. I am a certified Steadicam operator (trained by Garrett Brown, Steadicam's inventor, long before the company was sold) as well as an owner of the Steadicam Jr. for DV cameras. Steadicam shots are all about sophisticated dolly shots impractical for dolly crews. They also save time and money on indie features because a good operator CAN get reasonable lock-offs (witness the multi minute end of long Steadicam shot lock off in the interview scene in "The Shining") while also simulating crane moves with simple cherry pickers, and generally do fun stuff like going up and down stairs smoothly. Center of gravity is the focus of Steadicam operation. Whether you are home brewing a Steadicam-like devise, or renting one at some time, the object is to keep the center of gravity of you AND your rig as close as possible to being simple downward pressure on your feet. Anytime you do moves with the rig away from your body, well, get out the Doan's Pills for the coming backaches. Operating a Steadicam or clone thereof is more like a tango with the rig as your partner. The rig stays as close as possible to your body to keep the weight over your feet. As to the Steadicam Jr., as others suggest, your arm may work for a short time, but eventually, you succumb to the weight of a PD150 or the DVX-100 (which requires EXTRA weight on the sled to balance [wireless receivers work well with velcro in this instance] the thing.) There's also a problem with panning (Steadicams LOVE to pan, tilt, boom a little, and such in the "real" world) on the Jr. because the control surface is too small - you find it too easy to disrupt the flow and create an annoying yaw, even a rocking yaw as the unit settles itself. There's also not quite enough size in the sled to inhibit yaw in the first place. That all said, when the Steadicam Jr. works (YOU do everything right) it passes for the real thing in DV. It also collapses quickly and makes a decent shoulder mount. Over time, doing a lot of shots with a Steadicam Jr. - you find the operator's muscles begin to lock from the oppressive weight of the rig, you begin to see a sine wave "pulsing" as the horizon smoothly moves up and down in correlation with the footsteps the operator is attempting to remove. Now that the patent has run out, apparently, on the Steadicam, the generics are beginning to abound. There were many "steadiclones" at the NAB show last year, even a sexy one from Sachtler, and so, I should think someone will put out a pro DV/DVCAM steadirig which features 1) the addition of MASS to the DV camera [heavy as a PD150, DVX-100, or the less professional XL1 are, they are not heavy enough to emulate the stability equation of a big film camera] 2) a vest and iso-elastic arm with spring tension appropriate to the lighter overall weight, and 3) a set of accessories for low mode, radio focus, proper docking, vehicle rigs, and the like. This, of course, assumes the camera owner has already purchased wide angle capability - standard stuff for human mounted Steadicams (but not really needed in vehicle mounts!) Dispensing with the idea of Steadicam for a minute, the independent producer can get a lot of bang for the buck by picking up a good used wheelchair. Smooth floors and wheelchairs are a great "poor man's dolly." Also useful to add visual dynamics to a show: jib arms, which can add their own stable motion, panning, tilting, and booming with smooth lock-offs. You can design shots with the boom arm in mind which can get actors walking and talking. Poor man's track dolly: skateboard wheels mounted to an angle iron so as to ride on PVC pipe. A small wood platform with such wheels, then add your boom-equipped tripod (tie it down!) and suddenly, slick images at little cost. Smaller versions of this technology can make for interesting tight interiors shooting. Finally, with the small size of the PD150 and DVX-100, practicing handheld operation is well worth the time, and perhaps investment in time and experimentation in finding what handheld rigs work best for you. Handheld is the stuff of kinetics, which can add to drama. Well, 'nuff said for now, Richard Brown
