So I finally pulled the trigger and ordered a Sony a7R VI because I saw a bunch of videos saying the image quality is insane for video. Total newbie here, I basically just used my phone for everything up until now. Im moving to Seattle next month for a new job and I really wanna start making high quality vlogs and some short documentary pieces about the local hiking spots. Honestly I feel like a fish out of water looking at all the gear sites.

My budget is kinda tight since the camera practically emptied my savings account but I dont want the footage to look shaky or dark. Ive been reading about gimbals and different kinds of mics but the options are just overwhelming. Like some people say you need a cage but I dont even know what I would bolt onto it besides a light? Then there are the memory cards, do I really need the expensive ones or will the cheap ones just ruin my footage if I try to shoot in those big fancy resolutions? I dont even know if I have the right lenses for video versus photography, I just got the kit lens that came with the body.

Everything seems so complicated and I keep worrying that I bought way too much camera for my skill level. I feel like such an idiot asking this but what are the absolute must-have things I need to actually go outside and film something without it looking like a total mess? If you had to start over with just the basics to keep things manageable and not super heavy while hiking, what would you get first?
