Hello, I'm justin and I'm 15 years of age. I have recently been inspired to start mostly videography but some photography. I am looking for equipment such as (CAMERA, MIC, TRIPOD) now my budget would be 2000$ for all of this. I will be doing cinematic footage. I will mostly be taking videos rather than photos. Also I have a question on lenses. I have no idea what 15-300 mm means. I don't know what any of that means. Could someone explain. That's the reason I am not asking for a lens because I would love to understand what it means first
