My best friends daughter has asked me to take video of her wedding. I don't do video (i did tell her this) but she can't afford a pro so i will be doing this for her.
My question is, what lens should i purchase to do this? I will be using my 7Dii. I would like auto focus and not sure if what i have will do this. I have a Sigma 17-50 that i think would be a good focal range but i assume i would have to manual focus. Any help on this would be greatly appreciated.
