I'm just getting into Filmmaking/Videography, sorry for "noob" questions. I have a budget of $250 to spend on a lens, what do you recommend? Aside from Youtube Skits, whatever lens you recommend, could I ever use it professionally, like filming a commercial for a small business or church? Last question, could I use the lens you're going to recommend for Music Videos? My friends have a little "rap group" and they'd like me to shoot their first music video. Equipment I have: Canon T3i (Kit Lens 18-55) MacBook Air May get a Rode VideoMic "Go", would an on camera shotgun mic be fine for skits? Thanks!
