I had before buying the 30's a longer Sirui K20X in operation and find both heads really very good. Now I had promised me from buying the 30-head that does not nachrutscht when I fix a position. Unfortunately, that makes the same. I am very much in the hectic everyday photo go and must quickly adjust the head, the behavior of the head is disappointing as selbt slight deviations in determining my needs are problematic. Something can the 30-head still better: The camera lens unit does not rotate on the head, if I take the stand in the hand and the whole construction hinstelle elsewhere. After all ... (No, actually one should indeed a camera lens unit does not carry the tripod, in practice, but it looks different when you for example. Quickly change the location in very hectic situations and must be ready to fire.)
If you want to go to the portrait mode, one has with this and the 20-head the same problems: Both must show the recess at the head in the direction in which you tip the camera to portrait mode, must also the screw on the camera plate in the opposite direction show, otherwise the camera can not be in the 90 ° angle bend.
CONCLUSION: Beautiful head with good adjustment. Complicated practical obstacles you have to take into account: In portrait orientation, the recess at the head must point in the direction of tilt of the camera, while the screw of the camera plate must face the other way. For intensive practical photography with tripod a real no-go.
