The Markins Q20i is a knob-type (Quick Turn) ball head from the Q20i Series, recommended for large-format cameras and super-telephoto lenses.
The Q20i Series is our top-of-the-line series with a load capacity of 50 kg. In addition, there is the Q10i Series with a 45 kg load capacity and the Q3i Series with a 30 kg load capacity. Across all series, the exceptionally smooth movement and precise friction control that locks firmly in place are outstanding features. They are highly regarded for ease of use and exceptional stability.
It can also be used with confidence in extreme environments, including frigid climates and dusty deserts, as well as virtually any shooting location.
For your reference, load capacity standards vary among manufacturers, making it difficult to judge by numbers alone. Therefore, we have prepared a demonstration video. To clearly show that it securely holds any equipment, the demo features an incredible 9 kg test bar mounted on the standard Q10i Series.

As you can see in the video, thanks to its extraordinary load capacity, the equipment remains completely still even when you release your hands, yet it moves precisely in response to the amount of force applied. This enables safe and quick composition adjustments.
Therefore, you will not experience issues such as the equipment suddenly dropping when you loosen the knob to recompose, or a heavy lens gradually tilting downward even after being firmly tightened.
