So my friend got married and his photographer was garbage. The lady wasn't even around for some important moments, and crapped out early during the reception. So I took a bunch of pictures just to make sure my friend had some. I used my phone but they came out surprisingly good. Anyway, I was thinking of advertising locally to do photography, but I can't show up and take pictures with my phone.

What kind of camera / lenses do I need to buy for wedding photography?
