Whoa, love the a6400! Its such a fantastic little camera, honestly one of my favorites for travel. Quick question tho before you pull the trigger... what kind of lenses are you gonna be using most? Like, are we talking tiny primes or are you planning to mount some big heavy zoom glass on there? Knowing that makes a huge difference for stability! Im always super paranoid about my gear tipping over in the wind, so I stick to the pro brands. Honestly:

• Just get any carbon fiber legs from Benro, they are legendary for a reason!
• Look at Sirui too, their build quality is basically top tier for the price.
• Vanguard is another fantastic way to go if you want something sturdy. Seriously, you cant go wrong with any of those brands, they are so much more reliable than the random stuff you see online! Let me know about the lenses tho, it really helps narrow it down.

I use Manfrotto Befree Advanced Lever 4-Section Aluminum Travel Tripod. This tripod is incredibly sturdy yet surprisingly lightweight, making it perfect for both photography and plein air painting. I've been thoroughly impressed by its performance. Setting it up is a breeze, allowing me to quickly get ready to shoot or paint without any fuss. When it's time to hit the trail, the tripod folds down into a compact size that's easy to carry along on hikes. The portability is a huge plus. Overall, this is an excellent tripod that I would highly recommend to any photographer or artist who wants a reliable, easy-to-use, and easily transportable tripod. It has exceeded my expectations and proven to be a fantastic addition to my gear.

Ok adding this to my list of things to try. Thanks for the tip!

The best choice is to get Peak Design traveling tripod.

I use the SmallRig AP-20 Carbon Fiber Tripod, a great tripod for a6400.

I use VICTIV 74” Camera Tripod, works well: https://www.bhphotovideo.com/c/search?Ntt=Camera+Lightweight+Aluminum+Compatible+Cameras&BI=8941&KBID=10361&SID=12345&DFF=d50
