I looked at a lot of compact tripods before I found this gem

Removable center column
Removable ball head that uses a common dovetail plate
Folds to about 12" and has 3 usable leg positions
The legs use a very fast and strong twist lock

The Sirui ball head is smooth and strong but ultra compact

I will warn anyone looking at the Mephoto Backpacker tripod
It does not have a removable center column and it does not have the 3rd leg position
Both of these are needed to be able to get low

The Sirui tripod will also go up to the mid 50's but I am not interested in a tall tripod from a backpack
