Todd has a business and wants to start doing video blogging, or "vlogging." What equipment does he need? He'll be starting from his desk but he wants to know what camera to get. Leo says it depends on what Todd is going to be doing. Todd wants to have a set with a background screen. Leo says that in Todd's case, a camcorder with an external microphone jack is a good option. DSLRs do this. Point and shoots would help keep within his $500 price range and the video quality is really good. Even a smartphone like an iPhone or Samsung Galaxy S5 would do the trick as well, and he can use a microphone to improve his audio.
Leo recommends looking at DPReview.com. They have spec sheets and an external mic jack is one of the options to check.
