I'm taking a multimedia production class in the fall semester and need a camera that can take both solid pictures and videos. An external mic input would be great. My budget is <$700, but I can stretch a little bit for a better system. Right now I'm almost sold on the Nikon D3300 as it offers good 1080p/60 video with an external mic input and great picture quality. I'm curious about mirrorless, but iffy about the lack of an EVF. I'm looking for any recommendations that I may have overlooked. Thanks for any and all help, I've been out of the loop for a few years now.
