+ Very fast and flexible adjustment of the camera position.
+ About the Friction can well adjust the smoothness of the ball on the weight of the camera.
+ My camera is held firmly and without shaking. My maximum load consists of a Nikon D90 + a not very lightweight 24mm PC-E Nikkor what the head is more than enough. I've also made a "laser pointer" test, along with my Manfrotto 190XPROB vibrates nothing.
+ The quick release mechanism is well protected, so that the camera can not fall out accidentally.
+ The head made a very stable and lasting impression that will last a lifetime at it.
+ Built-in panorama function: You can rotate the camera precisely 360 ° without releasing the ball head and thus to adjust the inclination. If you have a tripod with fold-down center column (about Manfrotto XPROB), you can shoot even vertical panoramas.
o Strangely enough, one has when you put the camera for vertical shooting to the side, a little over 90 °. But well, that does not bother me really.
o The movements are not running "smooth as silk", for occasional DSLR video recordings of the head may be nothing, but I have not bought it.
- The only improvement that would occur to me, would be a built-in level on the camera plate, at least for the horizontal alignment would certainly fit well off.
Otherwise, this head is perfect and fits perfectly on my requirements "demanding amateur" more spherical head I do not need.
