Just got me a Gitzo GT2540 tripod. Now looking for a ballhead. I currently have a Canon EOS 5D Mark II with 24-70 f2.8 Lens and a RRS B5D2-L L-PLATE. In very near future another lens will be added, likely to be a canon 70-200 f2.8 is usm or a EF 70-300 f/4-5.6L IS USM. Searching for a long time now for a proper ballhead. Somehow I cannot choose between Markins q10 or Arca Swiss Z1. The Z1 is quite heavy and considering its size would it be a good option for a series 2 tripod? Or is there a valid reason to opt for the Q10 instead? Since I do have a RRS L-plate I’ll opt for a B2 LR II: 60mm clamp anyhow.
