For the weight of the bridge camera, the ball screw is obviously not designed, the camera may not securely fixed. However, you can help yourself: if you have fixed the locking screw, hold it there - that's enough for verwackelfreie recordings. This criticism refers only incidentally to the ball head - legs are unlike complains in some reviews, safely on the ground.
For Bridge cameras this tripod is only a compromise, for D-SLRs (of course) totally unsuitable - but its strengths unfolds the tripod for compact cameras - my kids are happy about it anyway.
