Just an iPhone? Very nice quality!Lots of factors, I'd imagine. First, how much money you have to spend. If you make a good living, then a fancy camera isn't a big expense. If you're a student without much spending money, then it's going to be a big sacrifice.
Also, it depends on what your goals are. If you're a filmmaker, then great equipment is going to be helpful to set up shots that work better in-camera, and you'll want to use different lenses and filters for effects, etc.
For me, I've been at this for 3 years with just my iPhone, and though I'd like a better camera, my needs are really basic, camera-wise.
I also spent a couple of thousand Euro, but that's okay, because filming is my biggest hobby and I do other projects apart from YouTube that generate income. I think it's always important to remember that in the end not the camera makes the good video but you.
Between lights, camera, final cut pro etc...it adds up. Sometimes I feel like i'm spending too much, other times, I feel like not enough.
Some people started their channel with an iPhone and a dream...I started mine with lights, camera etc...yet Always find that I need to buy this and that...
