Tripods it fits
"Maker says it fits" means the head maker or the tripod maker sells the two together or names the pairing on its own page. "Interfaces match" is our check that the tripod's published top (thread, bowl or Arca clamp) meets this head's published base; it says the parts connect, not that the maker has tested them. Rig figures are calculated from both makers' numbers.

Rig weight is the tripod's published weight plus this head's; rig load is the lower of the two published ratings. Blank where a maker does not publish the number, or where the tripod is sold with its own head on top.
