I bought a Nikon D3100 a couple years ago and have been shooting with the kit 18-55mm kit lense ever since. I'm a college student and really just a hobby photographer so I'm not looking to spend a ton of money. I know good lenses are expensive but I'm probably looking to buy used. I shoot a lot of landscapes but I also like shooting up close details. I'm also starting to shoot more portraits as well. I'm also going to Costa Rica in a couple months so I will be taking some wildlife shots as well. What lenses do you think it would be most beneficial for me to have? I'm thinking a telephoto, but I also like the idea of a wide angle and 50mm prime. Ideally, I will eventually buy all three but I'm going to have to bu them one at a time. any recommendations?
