I just got my hands on a Sony FX3 and I am so incredibly excited but honestly I am also totally lost. I saved up for months working at the cafe to finally buy this thing because I see all these amazing travel videos on YouTube and I wanted that same look. The camera body alone was basically my entire savings lol. I have this big trip coming up to Iceland in like three weeks and I really want to capture those massive mountains and the waterfalls but I realized I dont actually have a lens yet. I thought it just came with one but it didnt.

So I started looking online and everyone is talking about wide angle lenses for that cinematic feel but I am so confused by the numbers. Like what does 16mm or 24mm actually do? Is a lower number better for seeing more of the view? I want that look where the scenery feels huge and epic like in a movie. Someone mentioned a G Master thing but those are way too expensive for me right now. I have maybe $900 left in my budget for one good lens that can do it all for this trip. I am really worried I am gonna buy the wrong thing and get to Iceland and realize I can only see like a tiny sliver of the landscape because I picked the wrong number.

Is there a specific lens that is easy for a beginner like me to use? I keep hearing about f-stops too and I dont really get if that matters for video as much as photos. I just want something that makes the footage look professional without me having to be a genius to figure it out. Also do I need a zoom lens or a prime one? I dont even know the difference really. I saw some brands like Sigma and Tamron that are cheaper than Sony but I dont know if they work the same or if they will break the camera. If anyone has a recommendation for a lens that would work for wide shots on an FX3 that wont break the bank totally please let me know. I just want my Iceland videos to look halfway decent since I spent so much on the camera...
