so i finally got my first real camera it is a sony a6100 and i am so stoked to use it for my sisters wedding in portland next month!! but right now i only have the flat kit lens it came with and people keep telling me i need a prime lens if i want that blurry background look for portraits. i have no idea what im doing honestly lol. so i was thinking maybe a 35mm or a 50mm because those seem to be the ones everyone talks about on youtube but then i saw a 16mm one and got super confused. my logic was that a bigger number means it sees more of the room? but then i read somewhere it actually zooms in more which is the opposite of what i thought. i have about 400 dollars saved up and i really want something that makes people look good but also lets me take some cool shots of the coast while im out there. is a 50mm too much zoom for indoors? i dont want to have to stand in the hallway just to get my friends in the frame haha. sorry if this is such a basic question i just dont want to waste my money on the wrong thing since i spent so much on the camera itself... what do you guys think is the best first one to get?
