i am so confused right now and honestly about to just give up and use my phone for my italy trip. i have this nikon dx camera (d3500 maybe?) and it came with two lenses but switching them while walking around rome sounds like a total nightmare. i just want one zoom lens that can do close up stuff and far away stuff so i dont have to mess with it. there are so many numbers on these websites and it makes my head spin and i dont want to buy the wrong thing.

• budget is $500 or less
• i need it in two weeks
• has to be easy to use

sorry if this is a dumb question but what is the one lens i should buy so i dont have to carry a bag of gear...
