After 3-4 weeks of irregular use or testing I finally rather disappointed. Initially, the enthusiasm was great. With my telephoto (300 + TC20) of GH3 was hardly required. Pleasant was the much better and more comfortable handling when taking pictures. My back has thanked me. The disappointment was later relatively large, when I realized that the nodal point in China probably is different from us, you mean. In the horizontal axis, I can adjust the telephoto to the nodal point. But in the vertical axis there is no possibility. Here, the nodal point is offset by at least 1 cm from immutable axis of rotation of the stand. The mentioned in the product description Nodalpunkt thus refers only to an axis! Message to the German distributor remained unanswered to this day. To use the GH3 for multiline panoramas can be implemented at most with the smaller DX DSLR. Remain full-frame DSLR sidelined. As attractive as the price also was / is, but I would not return the money to spend for it. Then, check first to 400 and a good Really Right Stuff. The Chinese are not ready. They probably still have too much dollar signs in their eyes and there one overlooks ever one centimeter. Too Bad.
