A:AnswerIf there is a way to do vertical phone videos with it, I haven't figured out yet. I believe you can do just horizontal. Perhaps someone else has figured that out, but I haven't. Love the adapter (for horizontal capture) and the tripod though.
A:AnswerNo, an A7iii with any decent lens is beyond this tripods capacity of 3.3lbs.

My video shows why this is not a good fit for that size of camera/lens.
For a 1500$+ camera set you should really consider a decent set of legs and head so you dont damage your equipment and lose thousands.
Something similar to this leg set (https://youtu.be/Z7kWYrTGvnU) or the smaller version (Benro TMA37AL)
A:AnswerYes it comes with the cell phone attachment. Love this tripod. because each leg adjusts on it's own, it makes it easier to keep it straight on uneven ground.
A:AnswerIt doesn't come with a blue tooth remote. However, I can use my phone as a blue tooth remote with my camera (Sony Cypershot). It's a nice sturdy tripod with metal legs that are extendable. The top parts are plastic. It comes with a carrying case and a cell phone attachment. It's a good entry tripod. I took this the first night it arrived.
A:AnswerThe Ttripod can support devices up to 3 lbs, so you could mount an iPad. However, you would need to buy a separate tablet mount as the included one is only big enough for a smartphone.
