Just a heads up for anyone considering the new (2015) Gitzo traveller series 1 tripods; the new panning base diameter is 35mm compared to the Markins 50mm. I imagine Gitzo is likely trying to lead people to buy their new/matching 82TQD ball head (no friction control and not Arca compliant, but possibly still decent (?), haven't seen a review yet) which looks to close up even more compactly.
Anyways, I had no luck searching the web for this exact combo before purchasing and thought I'd share in case someone here was considering them. Apologies for the off topic thread (though it's quite light and suits the a7rII)
