Tbh I’m gonna have to disagree with going the mini tripod route for this specific phone because the S21 Ultra is a total beast and honestly way too heavy for those basic plastic joints if youre trying to do long exposure or use the telephoto lens properly without it shaking like crazy. You realy need something with a higher payload capacity and a legit ball head to keep it steady or the micro-jitters will ruin your 100x zoom shots. * Sirui 3T-35K - This one is basically the gold standard for high-end mobile setups since it’s all aluminum and the stability is miles ahead of the ulanzi or joby stuff plus it can actually hold the weight without drooping over time.
* Benro MeFOTO Backpacker S - If you want a real travel tripod that actually extends to eye level this is the way to go because it handles the weight of the Ultra effortlessly and the build quality is just way more premium. Idk I just feel like if you’re spending that much on a phone you shouldn't cheap out on the legs or youre gonna end up with blurry shots whenever the wind blows lol just my two cents.
