Starry sky above Daming Lake, EOS 6D + 16-35 f2.8 16mm, iso640, f2.8, 5s, a star trail made of 300 images. I gently loosened the knob to slowly rotate the camera for an accurate composition in the viewfinder, without needing to reserve a space for camera drooping. Despite the low temperature, the Gitzo GH3382QD ball head rotated and locked rather smoothly. on a freezing January 23 rd, and the weather app on my cellphone read a temperature of -15☌. I arrived at the bank of Daming Lake after 4 a.m. It better facilitates my use of a head if the angle scale is on the head body or on both the upper and lower parts. However, I often set up the tripod at places such as the edge of a cliff, making it impossible to rotate the tripod with the mark to check the scale. What’s strange is that almost all the heads I’ve seen feature a scale on the base and the rotating head body only has one position mark. The head provides a horizontal rotation lock knob and horizontal scale to ensure a precise angle of rotation when mounting tabs. The vertical axis guarantees the direction of rotation is parallel with the horizon when mounting tabs.
There is a horizontal bubble next to the quick release plate and a horizontal line on the ball that matches the line surrounding the small “window” on the head body, which serves to ensure a perfectly vertical strut. This head can fit most Arca-Swiss quick release plates, which is good news for those who prefer L-type quick-release plate tabs. I once borrowed a friend’s ball head and was confused by the three knobs, each of a similar size. The two knobs are clearly marked to avoid confusion. This head is creatively designed to integrate the damping control into the thick lock knob so there are only two lock knobs on the head, giving it a very compact structure. WS2 has an extremely low coefficient of friction, so when the head is rotated, the locking mechanism provides smooth damping and locks the head effortlessly to prevent it from drooping to the maximum extent. By contrast, traditional ball heads always use PTFE, the material used as a non-stick coating for cooking pans. This material is the smoothest material known to the world. The biggest highlight of this head is the use of a tungsten disulfide (WS2) coating on its surface.
As a flagship model of this series, the Gitzo GH3382QD has a ball diameter of up to 49.4mm, but only weights 0.77kg because of its hollow metal ball. The Gitzo GH3382QD ball head is the latest model of Gitzo’s center ball heads. The cold front finally gave me a chance to try it out. I received the Gitzo GH3382QD ball head several days ago, but have been unable to use it due to the smog. Meanwhile, the cold wave swept away the haze that had plagued the North China Plain, bringing with it sunny days. A severe cold front hit Ji’nan at the beginning of 2016, resulting in snowfall and a drop in temperature down to -17☌.
