The Velbon QHD-61Q is one of two top-end ball and socket heads from Velbon, the other being the larger QHD-71Q. Like that model, it separates itself from its cheaper siblings with its magnesium-alloy construction. But at just 310g it doesn't add much to the weight of the tripod on which it's mounted. The head can support a maximum weight of 4kg, which is sufficient for most pro DSLR and lens combinations.
