I'm a complete newbie to DSLR cameras (I've never used them before), but I've decided to take the plunge and upgrade from a camcorder to a great quality camera. I know that I have a lot to learn about DSLRs, but I wanted to give it a try. I take pictures, but I will do a lot of filming for my YouTube channel, and I want a camera with good video capabilities. I have done some research on the Rebel t5i, and thought that was what I wanted because of the autofocus and the flip screen, but after reading about the Rebel t6i and the 70D, I think I might be changing my mind. Also, for whichever camera I buy, what lens should I start with? I know that I want a 50mm/f 1.8 for video, but should I get the 18-55mm or the 18-135mm for picture and video as well? Thanks!
