The ease of use is disconcerting. I just took 30 seconds to find how to remove and return the center column. The rocker is fine. Manfrotto to a really well-designed system. The tightening of the central column is frank, there is no fear that it descends alone. Similarly the central column, once loosened, rotates on itself, something I did not know to buy, which is very useful.
The tripod is very stable in all positions with one caveat légé when the column is at an end, but it takes a 40D with a 70-200 F4L without flinching.
Key will be appreciated supplied to change the clamping quality (mine are very tight) of fixations feet, grease in the joints of fasteners, evidence that the material is delivered to last, the great ballast and integrate the bracket to a conveyor belt, the small cap protected the fastening thread of the patella.
Noted, I am surprised by the weight and size (folded) of the craft. On paper it is less impressive. Especially with the ball mounted on it which adds to its own weight and dimension (494RC2 for me).
Not disappointed with my purchase.
