Looking for a ballhead for your tripod legs? A ballhead uses a kind of ball to allow free rotation in any direction. Most photographers prefer them over pan/tilt heads.
My favorite ballhead for its rock-solid stabilty is the Burzynski head. No other ballhead comes close to its tank-quality sturdiness, capable of supporting anything by virtue of its robust and simple design. It is best suited for a medium to large tripod.
The major downside (for some uses) is that the head cannot be flipped more than 45° to the side. That’s usually not an issue when using an L-bracket, but it is a show-stopper for a vertical counter-shift with shift-lens stitching.
I currently favor the Arca Swiss Cube, but the Burzynski is far less expensive and very simple and durable in design, highly recommended. US buyers will have to find it abroad.
