This remains fixed at the telephoto, with more than 1.7 kg no longer interfere with the 24 extra grams in freehand operation also. The plate itself is made of metal and can be seen from the original series, as of Cullmann -not even with the stands only the magnesite Row- is included. It fits exactly nothing jammed, unstable or has game. Even tightening without tools by means of a thumbscrew, the wing is retractable. These points are very important, especially in the heavy telephoto for me, especially since I do not have a balancing arm and am too lazy to build balancing weights.
To this end, a note: cheaper replicas (available for 6-7 euros) are usually made of plastic, have only a simple instead of the wing screw and video pin no. These are therefore useful in my eyes only for indoor applications with smaller lenses.
Conclusion: I am satisfied, especially as the extra cost compared to cheaper replicas designed but relatively moderate. For a savings of three or four Euros in my opinion, the risk is not worth.
