I am not being rude to either you or Gitzo.
When you give them money and they hand you a product it may be the last time you see each other. The things they supply are so well made that you would be hard pressed to break them in a lifetime. Their best bet for repeat business is to keep designing unique camera supports - you may never woear out the last thing you bought but you might be so pleased with it that you'll come back with more money.
Thus the studio three-way head you see in the top image. The
GHF 3W.
Under a kilo weight. Supports 13 Kg.
Arca/Swiss plate included.
Three way fluid damped.
Foldable levers.
Horizontal/vertical option when tilted.
Locking lever to keep camera on head even when you lose yours.
Rotatable levelling bubble.
The price is serious folding money but if you want a rock-solid head for your rock-solid Gitzo tripod here it is.
I can't have one because I haven't finished my Gitzo Studex 5 and large format head yet. It's been holding studio cameras since 1990 and I still haven't chewed it up. I am starting to think it won't break, but I will.
