The tripod is absolutely suitable for video, 2 drops of oil and the "Anfangsruckler" are gone. Stability in itself is also acceptable - at ausfgefahrenem telescope wirds already shaky - here are night shots to use only self-timer otherwise (but only minimally) the objects are blurred in the distance. The weight of a D5100 with 18-105er keeps the Quick Adapter easily - here I did not fear that the day passed.
