First of anything about the product itself:
The shoulder stand comes with several essays and a cloth bag, which is very convenient for transportation. The various attachments will make sure that you can install different cameras at different heights. In an essay, a quick release plate is what is also very convenient. Through these articles, the tripod is also adaptable to shoulder it left or right - ie also suitable for left-handers.
The quality of the stand and the essays are adequate for the price, more one must not expect as well. For the tripod is very light, which greatly increased the comfort and simplified transport.
The shoulder stand is certainly not for everyone. You have to know exactly which devices it is suitable, and how you want to use it.
For smaller camcorder in the consumer sector, it is well suited. Very good (I've used it myself) it is also for newer digital SLR cameras with movie function, such as the Nikon D90, the Canon 500D or the Canon 5D Mark II.
For larger camcorders it certainly is not appropriate because the holder is simply too small to ensure a secure grip and ergonomics well is no longer suitable.
When filming his movement you have good beherrschein despite the shoulder mount. Breathing (movement of the thorax CONFERS on the tripod) and a slight tilt to the left or right and also steps can check wear on the image. Ueubung is so popular!
