Frage von PeteH:
Hi Folks,
I would have been a recent owner of an ABC Handyman Steadyam with monitor and use these with a Canon 7D. Perhaps you have the decisive evidence. My camera weighs 1371g complete. In the user manual is that the trim weight should have approximately 30% of camera weight. In the 1371g would thus about 411g. In another article, I'll leave that trimming weight should be about as heavy as the camera. Therefore, first question:
1. Offices of major terms and conditions as it is this 30%? Since the joint of the monitor holder is pretty synonymous Swallowed and the monitor does not function anymore (unfortunately) for me. Do I want to leave him and of course a need for new counterweight.
2. Am I right in assuming that the surface of the counterweight as small as possible should be only? For the monitor with fabric sun shield takes, and even a relatively large area. Or is the surface is perfectly true no preference, the main counterweight?
To meet the 30% trim weight, I had s.Anfang the monitor, replaced by a small wood plate. From the surface, only a little larger than the Monito and thus a counterweight of 452g was reached. The system was quote at least balanced in the state apparently. But I had with unpleasant side oscillations to fight. Now I've helped out once with a small steel weight which weighs 296g and which I simply glued to the Trimmstab. I feel already to have less lateral oscillations, however, I ask myself the question:
3. I think the best focus on universal joint? I Align the trim weight to the top, middle or rather prefer the bottom s.Trimmstab? I know that the cause of course all a matter of practice, but perhaps someone has important tips for me when using a (Canon 7D or 5D) SLR camera and the best positioning and choice of trim weights.
ABC leads naturally trim weights and fortifications in the range of accessories, if I knew how much the cost and where can I refer, of course I would buy more as synonymous, unless you mean, I can manage myself synonymous.

The Camera-weight must be by a combination of position and Height repeal of the counterweight below the Handyman joint. Sure, you will say, stupid would I have guessed. It should be necessary only in extreme cases, to use a greater or lesser weight as the other variable can change the position as fast and flexible (see red Picture below). Especially the Handyman can easily offset by the lower tubes than the traditional cane steadies. If the relative vertical 7D built by Optics somewhat top-heavy, must in any case below also show a counterweight rather forward. Sample images with the Canon XL, which are very very top heavy:

for this position enough. Short, many wobbler: Gegegewicht too high. If you really need a different weight, it tinker yourself, from aluminum tubes, with the crumpled paper and as coins and fill with endcaps shut you (cost-digit euro area).
Antwort von musicmze:
All physics is the fifth class, predict with more.
The Steadicam is simply a vertical lever.
You have a top weight (which is exactly known) and then the distances above and below the Kardangelenkts (where you choose below the distance a little longer than the above). So you can then trim the weight and experiment can work out in about it.
L1 = L2 x m1 x m2. when this formula is true in some, the masses above and below the equilibrium and the turning point are stable.
That with the 30% is total nonsense.
I have used synonymous with me for several hours and calculates the weight and then moved, etc. .. Just try. Gibts enough youtube videos

s.jetzt I see the Picture.
NEN above you can leverage on the joint of perhaps 4-6cm (center cam) and down 30-40cm loose Now you ausrechen you just about the proportion that the Trimmegewicht may perhaps be one tenth of the camera .....
