so i just bit the bullet and bought a fujifilm x-t5 because i saw all these amazing photos on instagram and i am literally so hyped to start using it!! im going on a huge trip to Kyoto next month and i really want to capture everything but honestly im totally lost when it comes to the lenses. the guy at the shop mentioned prime lenses are sharper than the ones that zoom in and out but i have no idea where to even start because there are so many numbers on them like 23mm or 35mm or 50mm and i dont really get what the difference is. i mostly want to take pictures of the streets at night and maybe some close ups of food and my girlfriend when we are walking around. my budget is kinda tight now after buying the body so i can probably only spend about 500 bucks maybe 600 if i push it. i just want one lens that stays on the camera all the time and does everything well so i dont have to keep swapping them out and getting dust inside the camera which sounds scary. sorry if this is a really basic thing to ask but if you could only pick one single prime lens to use for everything on an x-t5 which one would it be?
