I just got my hands on the Fujifilm X-H2S and honestly Im so excited to start using it but I am totally overwhelmed. I saved up for like a year to get this because I heard it was amazing for fast stuff like sports and birds but now I realized I dont actually have a lens that zooms in at all!! I just have the little flat one it came with. Sorry if this is a total noob question but what should I actually buy if I want to see things far away? I’m going on a trip to San Diego in about three weeks and I really want to take photos of my kids playing soccer and maybe some seals at the beach but I have no idea what the numbers on the lenses even mean.

Here is what I am looking for:

• budget is around 900 dollars maybe a bit more if its really worth it
• needs to be good for sports but also just walking around
• not too heavy because I’m gonna be carrying it all day at the zoo
• easy to use for someone who doesnt know what f-stop means yet lol

Is there like one lens that does everything or do I need to buy a bunch of them? I saw one that said 18-120 and another that said 70-300 and I am just so confused about which one would be better for a beginner like me...
