Video and mobile go hand in hand. 90% of consumers watch videos on their mobile. From Q3 of 2013, mobile video views have grown more than 233 percent. YouTube reports mobile video consumption rises 100% every year. Since people like to watch videos on the go, and the number of smartphone users is growing, your video audience keeps getting bigger and bigger.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
