I always travel with a tripod

Gitzo GT-0531 Mountaineer 6X Carbon Fiber tripod
I always try and have a tripod with me at all times.  Finding a sturdy tripod was pretty easy to do.  However, once you start to fly and carry your tripod through airports worldwide you quickly will look for something much lighter.
Carbon fiber has high tensile strength, low weight, and low thermal expansion make it a perfect solution to make tripods strong durable and lightweight.  So a few years ago I researched and tried a few tripods before buying my Gitzo GT-0531 Mountaineer 6X Carbon Fiber tripod. 
Weighing only 1.6 lbs, 20.9” tall folded, extends to a height of 51.6″ and can go as low as 10.6” with legs spread.

When looking for a tripod the smaller it is folded and then combined with a really tall height when expanded will make a tripod cost more.  The carbon fiber cuts the weight by 1/3 as compared to a similar tripod made of metal.

Manfrotto 492 Micro Ball Head
This tripod doesn’t come with a head.  I liked ball heads and needed again something small yet strong.  I bought the Manfrotto 492 Micro Ball Head.
This combination fits in a small carry on bag and keeps my camera steady when I need it.
